A Young Red-tailed Hawk’s Saving Grace

For two years, long-time Hawks Aloft friend and volunteer Larry Rimer monitored a Red-tailed Hawk nest site on the western edge of Rio Rancho, butting up to the escarpment near a network of large, high voltage power lines. When the nest revealed just two nestlings this year—as opposed to three the previous year—Larry paid closer attention to the site, visiting it at least weekly to “marvel at their beauty and study their behaviors,” as he put it.

On one recent auspicious Friday morning, Larry decided to check on the nest for the last time before heading out on a week-long research trip. The chicks “were close to fledging and [I] was hoping to see them fly,” he explained. Yet, when he arrived, only one of the chicks was in the nest. He lingered, observing the remaining nestling, realizing that it was not yet ready to fly, and worrying over what had happened to the missing chick. Maybe it had been predated by a Great Horned Owl?  Larry kept his vigil for more than two hours before deciding to head home. “Just then [I] noticed out of the corner of my eye something fluttering down at the base of one of the huge poles,” he explained. There, mired in the tar applied to the wooden electrical poles to keep them from rotting, was the other young Red-tailed Hawk, his feet and chest stuck in the now hardened tar. The previous day there had been a storm, and Larry’s best guess is that the gusts had knocked the bird from his nest and into harm’s way. “I couldn’t believe my luck in being in the right place, looking in the right direction, at the right time to find him,” Larry said.

Larry called Hawks Aloft where he was advised to take the bird directly to Petroglyph Animal Hospital. Larry worked patiently under the watchful gaze of the adult Red-tails until the youngster was free. He then transported it Petroglyph, where Dr. Kariana Jones treated the bird for dehydration, and gave him an initial cleaning. Later in the day, the bird was taken to a Hawks Aloft rehabilitator, Jim Battaglia, who, along with Larry, Steve Elkins, Tony Giancola, Gail Garber, and Dean Balmer continued cleaning the bird with mineral oil, Dawn dish detergent, and Goo-Be-Gone.

After being thoroughly cleansed of tar, the young hawk recuperated overnight. The following morning Larry, along with his wife Kim, Steve Elkins, Tony Giancola, and others, took the bird back to his nest site and released him. He lingered on the ground before climbing a nearby fence pole, all the while calling for his parents. After a time, the parents showed up with a huge rabbit for breakfast and the young hawk called out joyously. He flew nearly 30 feet to a nearby post, and at that time, Larry left the family to their privacy.

“I’ve had such a strong bond with this raptor, I’ve watched him grown from an egg to an almost flight ready hawk … It just couldn’t have turned out any better, with so many things falling into place to allow him to survive and be released back to his home nest,” Larry said of the experience. “It gives me hope for future rescues. I am one very lucky guy to have experienced this and [I] wouldn’t trade it for the world.”

Raptor Vocalizations

We’ve all seen and heard it. In commercials for an all-American truck, in movies about the wild, wild West. All too often producers depict a soaring bird, frequently an eagle or even a vulture, and tracked over the shot is the call of a Red-tailed Hawk.

Raptors are thought of as strong and tenacious animals, but that doesn’t always mean they have the vocalizations to match—the ubiquitous cries of the Red-tailed Hawk being the exception. Most raptors in fact have a weaker, high-pitched call. For example, here is a common vocalization of the fierce Bald Eagle:

You may think that, if the Bald Eagle doesn’t have a sharp, robust cry, then surely the Golden Eagle does. However, you may not find this to be true either. Take a listen:

Most of the studies done on bird vocalizations emphasize, unsurprisingly, songbirds. Oscine birds (a subset of Passeriformes) include the Brown Thrasher, Hermit Thrushes, and Starlings who illustrate great range with their complex voice boxes. These birds often emit sounds ranging from buzzes and clicks to trilling and warbling.

Birds of prey’s calls don’t tend toward the musicality displayed by songbirds, but are still interesting, varied, and quite often beautiful. Take for example this lovely, common call from the Red-shouldered Hawk:

Frequently film makers will even use a shot of circling Turkey Vultures paired with the cry of a Red-tailed Hawk. However, Turkey Vultures are largely silent birds, and vocalize primarily when very agitated and then it sounds a great deal more like a hiss, even a roar, then a cry.

Surely no one expects a Hollywood movie to truly reflect reality, and the objective of truth in advertising is often overlooked. A quick review of raptor vocalizations illustrates these points in a simple, often funny way. The next time you hear the cry of a Red-tailed Hawk emitting from a television or movie screen, take a moment to quietly fact-check the content of what you’re seeing, or better yet, head outside to find the authentic music of raptors and songbirds across New Mexico.

If You Find a Baby Bird

Robin Fledgling 6-12

A Robin fledgling discovered by Hawks Aloft Executive Director, Gail Garber

As spring progresses and the promise of summer takes shape in the form of longer, warmer days, a flurry of activity is taking place overhead. Birds are breeding and nesting, and soon, all the effort of courtship and nest building will come to fruition as a new generation hatches. For outdoor enthusiasts and bird lovers—especially those who have taken the time to provide a habitat for local birds in their yards—it is not uncommon to find a young bird, seemingly helpless and marooned. Yet, weak and clumsy as they may seem, it is a rare occasion when these youngsters need our help.

Frequently, young birds found on the ground are recent fledglings. This means they are just testing out their flight skills and it is not uncommon for them to end up grounded. If the bird appears to be mostly fully feathered, usually with short tail feathers, able to hop around and take short flights, it is likely a fledgling. If there is no looming danger to the young bird, leave it alone. Fledglings, while taking their first flights and gaining independence, are still in the care of their parents who are likely nearby. Keep pets inside and allow the bird to find its own way home. If this is an impossibility, perch the bird in a shrub or the boughs of a low tree.

Young Ferruginous Hawks

Occasionally a nestling may fall from, or be pushed from the nest before it is ready to fledge. If the bird is naked, or with very few feathers, it is safe to assume it is a nestling. If uninjured, take some time to try to spot the nest. If possible, simply place the nestling back in its home. The pervasive myth that if a young bird is handled by a human its parents will notice the scent and abandon the young is just that—a myth. If the nest can’t be located, you may engineer a small, makeshift nest from something like a berry basket or another small container with a few channels for drainage in the bottom. Line the container with soft materials and then secure it to a tree as near as possible to where the bird was found.

There are some exceptions to these general rules, however. If you find a bird, any bird, that has been injured by a cat, call a local wildlife rehabilitator. Almost always, a bird that has been attacked by a cat will need antibiotics. At Hawks Aloft we have a 24-hour raptor rescue hotline for birds of prey, and Wildlife Rescue, Inc. is also an option for birds and other animals that need rehabilitation. In addition, if the young bird is quite evidently injured (i.e. bleeding, wings drooped unevenly) or if you are absolutely certain that the bird’s mother is dead, secure the youngster in a warm, dry, and dark space and contact a wildlife rehabilitator immediately.

The impulse to help the animals we love is strong, but sometimes that care and concern isn’t in the best interest of those we seek to help. Often, the best thing we can do for the young birds we discover grounded is to resist the urge to intervene. If you have any doubts or questions about the appropriate course of action if you’ve found a baby bird, don’t hesitate to contact Hawks Aloft or a another local wildlife rehabilitator.

Differentiating Western and Eastern Bluebirds

After fielding a number of inquiries about how to differentiate between Western Bluebirds and Eastern Bluebirds, Gail asked me to use my space in this month’s online to detail how to distinguish these two closely related species from one another. Both species of bluebirds can now be found in the middle Rio Grande bosque year-round, but this was not always the case. During the early 1980’s Middle Rio Grande Biological Survey (Hink and Ohmart 1984), Eastern Bluebird was considered to be an uncommon winter visitor to the bosque and Western Bluebird was considered a rare visitor to the bosque between October and March. By the time we started our Middle Rio Grande Songbird Study in 2004, both species were regularly present in the bosque in at least small numbers during the winter. We began encountering Eastern Bluebirds breeding in the bosque in small numbers during summer 2004. By 2009, Eastern Bluebird had become a relatively common bosque breeder in areas with mature cottonwoods and/or large cottonwood snags. We did not begin detecting Western Bluebirds breeding in the bosque until 2011. But, Western Bluebirds have also become relatively common bosque breeders over the past two or three years, and may now be a more common bosque breeder than Eastern Bluebirds.

Male bluebirds are easier to identify to species than females. Males of both species have dark blue backs, wings and heads, with orange breasts. But, male Western Bluebirds have blue throats, while the male Eastern Bluebirds have orange throats. The orange on Western Bluebirds continues from the breast onto the scapulars (but NOT onto the sides of the neck) and down the back. In some individuals, nearly the entire back can be orange. In contrast, the orange on male Eastern Bluebirds continues from the breast and throat only onto the sides of the neck, with the scapulars and back remaining entirely blue. Another field mark to consider when differentiating males of these two species is belly color (this is often the quickest and easiest way to differentiate these two species). Eastern males have white bellies, while Western males have blue bellies. For those of you with particularly keen eyesight, Eastern Bluebirds (apparently) have somewhat larger bills than Western Bluebirds.

The females of these two species are more drab in coloration and more difficult to differentiate. Females of both species have bluish-gray coloration on their backs, wings and heads, as well as faded orange breasts. But, the overall patterns of coloration in females generally follows that of their male conspecifics. Female Western Bluebirds have bluish-gray throats and necks, while Female Eastern Bluebirds have white throats with orange continuing from the breasts onto the sides of the neck. Western females may have some faint orange coloration on their scapulars and backs, which the Eastern females lack. As with males, belly color can often be the easiest way to differentiate the females of these two species: Western females have grayish to bluish-gray bellies while Eastern females have bright white bellies.

When I encounter bluebirds in the field, the first things I look at are throat color and belly color. If the throat color is the same as the head color and the belly color is blue (in males) or gray to bluish-gray (in females) then I know I’m looking at Western Bluebirds. If the throat color differs from the head color and the belly is white, then I know I’m looking at Eastern Bluebirds. One final note: During winter these two species may occur in mixed flocks (and on rare occasions may be joined by Mountain Bluebirds) in the middle Rio Grande valley. This usually occurs in prime winter foraging areas with large Russian olive and/or New Mexico olive berry crops (or other vegetation supporting large berry crops). In general, however, these species seem to prefer the company of their own species.

Good luck with your bluebirding!

Get to Know Amanda Schluter, Hawks Aloft Intern

Amanda Schluter joined Hawks Aloft this January as a seasonal intern during a lull in her work season with the U.S. Forest Service. Amanda comes to Hawks Aloft with a strong background in field surveys and with lots of enthusiasm.

What’s your educational background?

I graduated in 2011 from the University of New Mexico with a BS in Biology and Biological Anthropology.

Tell us about your work history with the National Forest Service

After graduation, I worked as a biological science technician at the Cibola National Forest in the Mt. Taylor Ranger District for the summers of 2012 and 2013. My job was to conduct Mexican Spotted Owl and Northern Goshawk surveys for the majority of the field season (April through August). Because my employment was partially funding by the forestry division of the district, I also assisted them in timber sale layouts after the bird surveys were complete. I also assisted the Rangeland Management team with various surveys and recreation needs with campground and trail maintenance. This was a great way to understand the different roles of the various groups within the forest service.

For the 2014 field season, I worked in Pioneer, California on the Eldorado National Forest, located south of Lake Tahoe along Carson Pass. The majority of my work consisted of doing Northern Spotted Owl and Northern Goshawk surveys but I also was able to assist with stream bank alteration surveys and yellow-legged frog surveys.

For the 2015 field season with the Forest service, I worked in Flagstaff, Arizona in the Coconino National Forest. I was still mostly doing Mexican Spotted Owl and Northern Goshawk surveys. I also surveyed for Peregrine Falcon, narrow-headed garter snake, northern and lowland leopard frog, bats, and some sensitive plant species. I also assisted in the relocation of a prairie dog colony. This forest is unique because it has a large number of Spotted Owls which made surveying for them very fun.

How did you hear about Hawks Aloft?

I heard about Hawks Aloft from one of the volunteers, Chellye Porter. She heard about my work history and thought that I would be interesting in volunteering. She then put me into contact with Gail.

What has been your favorite experience so far at Hawks Aloft?

I have had a lot of survey experience but I had never surveyed for songbirds. I have really enjoyed that experience. I really appreciate how it makes you slow down and pay attention to your surroundings. Plus, I enjoy seeing the birds and identifying them.

I also really get a lot of enjoyment from visiting local schools for education programs. All the students have been really great and love to learn about the different raptors that we bring. Their excitement is contagious and it is great to teach someone something new.

What do you hope to learn here and how will it inform your future work?

Since the majority of my work in the past has been surveys for raptors, I really wanted to learn more about the songbird surveys and also migratory bird surveys. I also am interested in getting a different work experience beyond that. Being able to handle the birds and teach others about them is very appealing to me.

What do you enjoy doing outside of work?

Outside of work, I like to go camping and hiking a lot with my dog, Dexter. I also love crafts like knitting, crocheting and card making. Most weekends my friends and I will go to a local brewery or out to eat somewhere.

Introducing Aztec

Photograph of Aztec by David Powell

Although we’re not certain what happened to her, Aztec, the Great Horned Owl was brought to Hawks Aloft with some permanent injuries most likely caused by a collision with a car. She earned her name because she came to us from Aztec, New Mexico, in the Four Corners region, a small city near the Animas River, bordered by the ancient ruins at Aztec Ruins National Monument.

Aztec is a striking bird. One of the largest tufted owls in North America, Great Horned Owls like Aztec always attract attention. Aztec has fostered orphaned Great Horned Owlets in the past, and also has also provided Hawks Aloft educators with an opportunity to talk about raptor adaptations, owls in general, and the unique features of Great Horned Owls in particular.

Great Horned Owls are one of the most common owls in the United States. They are highly adaptable and make their homes in diverse landscapes—deserts, wetlands, grasslands, and urban environments—anywhere that there is some forested areas with semi-open spaces interspersed throughout.

This common and easily identifiable species of owl is noted for its long, earlike tufts, the white patch on its throat, its heavily barred underbelly, and distinctive hoot. Below you can listen to the typical call of a Great Horned Owl.

The tone of the Great Horned Owl’s various calls can vary by region, but the deep series of 4-5 hoots is never so different that it can’t be readily identified. However, males and females are known to perform a call-and-response duet, wherein the sex of the birds are distinguished by their variation.

Great Horned Owls, like all raptors, are carnivores. Built for secrecy and stealth, these birds can take down birds and mammals that are larger than themselves. They’re not picky eaters and have one of the most diverse diets of raptors in the United States. They’ll feed on small mammals and rodents, as well as scorpions, snakes, loons, ravens, doves, insects, fish, other invertebrate and even cats and carrion—whatever is readily available. They are one of the only birds known to prey on skunks—they have a weak sense of smell—and the Executive Director of Hawks Aloft has even observed a Great Horned Owl that managed to snag a Red-tailed Hawk. It’s Great Horned Owl’s incredible adaptability that has made them one of the most successful predators in North America. Typically, these owls spot their prey from a perch and descend for the kill. Yet, illustrating their versatility, Great Horned Owls have even been observed stalking prey on the ground too.

Owls like Aztec are sometimes migratory, although most populations show fidelity to a single site year-round, where they remain in their monogamous pair—though outside of breeding season, the male and female often roost separately.

If you’ve fallen in love with Great Horned Owls and Aztec, consider supporting her as she lives out her remaining years with Hawks Aloft. Aztec’s injuries make her permanently non-releasable, so she requires care from our staff. If you’d like to support her by providing food, housing, and veterinary care check out our Adopt-A-Raptor Program.

Through the Eyes of an Intern: Part 1

 

Education Specialist Taylor Tvede teaching students about Harlan the Red-tailed Hawk.

The first few weeks of my internship were spent assisting with education programs at local elementary schools.  Half of the programs consisted of bringing two avian ambassadors  to the school and giving a presentation regarding the bird and its history. The other half of the program was an activity to teach the students concepts about natural science. Since I have a history of work with the U.S. Forest Service, I found one activity, the fire ecology game, to be very interesting.

The fire ecology game consisted of having children act out two different scenarios that represent the very different outcomes of forest fires. In the first scenario, the children are divided into groups of mature healthy trees, immature trees, dead trees on the ground or mature unhealthy trees (these are given a bug to represent their illness). The mature trees were spaced out evenly with immature trees kneeling under them. One student is then given “the fire stick” and told to tap their classmates that are sick or dead trees. This action leaves the healthy mature trees enough room to stretch out and the immature trees enough room to grow.

The next scenario in the activity represented a forest that has had wildfires suppressed for years. Students were divided into the same groups as before with some assigned as healthy, mature trees and others as immature trees kneeling under them. Among these were still the unhealthy trees, which were again given plastic insects to distinguish them. Then, without any of the students moving an inch, the immature trees were told to stand up.  Everyone became very crowded. Then the unhealthy trees gave one or two of their bugs to a tree that was standing next to them, spreading their disease because the forest had become overcrowded. Then the student that represented fire went through and tapped all the sick and dead trees. After the fire, there were very few or no trees remaining.

The purpose of this exercise was to demonstrate that not all fire is bad for the environment. At the beginning of the exercise the students all believe that fire can only be bad. Beginning in the 1890s many of the forests in New Mexico have had fire suppression in place and have become overgrown. Prior to the suppression of fires, New Mexico forests were subject to frequent low intensity fires every few years. Because of this, forests did not become overgrown, which, in turn, kept future fires from burning out of control. With new scientific studies, this history has come to light and the Forest Service, along with other government agencies, is working to remedy past mistakes. This often requires forest-thinning projects followed by controlled burns.

Fire is such an important part of southwestern ecology. In fact, many plant species will only reproduce after a fire. The increase in plant reproduction is due to the nutrient rich soil, the increase in water availability, and newly available real estate opened up by the fire. Firefighters have noted that deer and elk will follow behind a fire and eat the burnt grass like they are attending a neighborhood barbeque. Many predators can be found in burn areas because their prey is attracted to the nutrient rich plants that are found growing there.

When a fire burns out of control in an overgrown forest, there can be devastating repercussions. Not only can people lose their homes, but, if all the trees in an area are burned, this can create many hazards. Without the trees, there can be severe flooding and mudslides. In addition, if there are no mature trees in an area, the landscape cannot be repopulated. After catastrophic fires, tree saplings are often planted in the area, but it can take decades before noticeable change is seen.

Fire ecology is a complex concept and many adults are still unaware of its importance in the balance of an ecosystem—especially that of the southwest. Teaching students about the importance of fire ecology will lead to a future generation that has a greater understanding of the ecosystem that they live in.

Why is the Crow Black? And Other Interesting Thoughts on the North American Crow

Last week during a school program at La Mesa Elementary School, we presented our Avian Ambassador, Indigo, a North American Crow. After discussing her history and talking about raptor adaptations and how a bird like Indigo differs from hawks, falcons, owls, and eagles, I asked the students if they had any questions.

A third-grader in the back of the room hoisted his hand up immediately and asked pointedly, “Why are crows black?” It is such a straightforward question, but one with a complex answer.

The answer is: no one really knows why species of corvid like the North American Crow or the Common Raven are black in coloration. The best guess that evolutionary biologists can give us is that flocking birds like crows use coloration as a quick way to identify other members of the same species.

In one story from the Sioux Nation, the crow was once white as snow. After continually thwarting the hunting efforts of the tribe’s cleverest hunters, they caught the biggest, most important of the crows and, as a punishment, intended to burn him. The crow was very sly, however, and got away, but his feathers were charred, and ever since, all crows have been black. In Lenape legend, the crow was once rainbow colored—the earth’s most beautifully feathered bird. During a long, very cold winter, the Rainbow Crow flew to the heavens to ask the Great Sky Spirit for help. He gave the crow fire to take back to the animals of the land. When Rainbow Crow returned to earth, however, he was a different bird; on the return journey the flame had scorched his feathers black and made his beautiful voice a harsh croak.

Regardless of why or how, crows and ravens are black from their bills to their legs. As extremely social birds, crows sometimes form flocks up to one million in number. Just imagine what that might look like overhead!

Besides being one of the few completely black North American birds, crows are also exceptional due to their advanced cognitive abilities. Scientists working throughout the world have proven the crow’s ability to recognize human faces—which is, incidentally, an extension of their keen ability to recognize one another. Crows are also known to have complex communication systems that include regional “dialects” and a long-reaching memory—for example, crows have been known to change their entire migration routes to avoid farms where a single crow has been killed in the past.

Since crows are well adapted to living among human beings, you’re likely to encounter them nearly anywhere—Downtown, Uptown, the foothills, near the Bosque, and beyond. Next time you observe one of these dark birds flying overhead, take a moment to appreciate their unique characteristics and intelligence.

Through the Looking Glass

I’ll never forget the morning when, as I sat studying outside in front of the large picture windows of my university’s library, a hummingbird collided violently with the large pane of glass. I watched the bird, which seemed so weightless in flight, fall heavily to the cement sidewalk. I was almost equally stunned. Several moments passed and the bird rose, shook itself, and flew off again.

This is the best case scenario for a bird involved in a collision with glass; most are not so lucky. Ornithologists at Cornell University estimate that one million birds are killed each year as a result of run-ins with glass windows. Some researchers put that number closer to one billion. According to the American Bird Conservancy, each household in the United States kills two birds every year, simply by having windows that aren’t adapted to the avian life around them. What’s worse, these fatal collisions are most likely to happen at home sites that have active feeders, since they attract more birds to begin with.

Birds aren’t cued in to the architectural elements that help us recognize windows, instead they see the reflection of the world around them or look through the window to another window on the opposite side of the house and see a gap to fly through, connecting them to more of their habitat. Frequently, during mating season, particularly territorial species may exhaust themselves bickering with their own reflections in windows, leading to exhaustion.

For bird-lovers cognizant of the risks that windows pose, there are several options that can make your home more accommodating to the wildlife around you. Research has shown that birds generally avoid flying through vertical lines four inches apart or less and horizontal lines two inches apart or less, so there are innumerable ways to break up a wide pane of glass and communicate the barrier to your backyard bird friends; surely one will appeal to you and suit the design of your home.

One simple and aesthetically pleasing DIY solution is incorporating paracord, also known as parachute cord, outside of your window. Sometimes called zen wind curtains, these heavy cords are hung several inches apart near the top of the window and weighted with knots at the bottom. The dark colored cords break up the windows sufficiently and achieve an estimated 90 to 100 percent reduction in bird glass collisions, and are pretty attractive to boot.

There also are several different varieties of adhesive tape that can be applied in patterns to windows that obscure the clarity of the window just enough to deter birds without compromising the striking New Mexican sunshine that filters through. These options include American Bird Conservancy developed Bird Tape, durable enough to last up to four years; bird-safety films that can be applied in striped patterns or as a solid coat over glass—these have added benefits of reducing heating and cooling costs and providing greater insulation in your home; and there is also adhesive dots that can be applied in a “frit pattern” that is pleasing to the eye while simultaneously protecting birds.

Other helpful and easy fixes include relocating feeders farther from troublesome windows, hanging lightweight, reflective objects (i.e., all those old CD’s that have practically become obsolete), or even attaching branches on the exterior of your home that obscure windows and slow down birds as they approach.
Glass collisions impact migratory and backyard bird populations to an undue degree, including a number of threatened species. Because collisions are just as likely to injure or kill a healthy, breeding bird as a less robust individual, their impact on bird populations is even more worrisome. Simply considering the design of your windows and the ways in which you can make them more bird-safe can provide a boon to your local bird population.

Adventures on the Armendaris

This summer the Hawks Aloft team was granted nearly unlimited access to the expansive Armendaris Ranch owned by Ted Turner. The ranch itself stretches from Truth or Consequences in the south all the way to Bosque del Apache, encompassing a whole mountain range and thousands of acres of habitat for all kinds of wildlife.

 

But we came for the bats. The Armendaris Ranch plays host to many lava tubes, and those lava tubes are the home of a massive maternity colony of Mexican free tail bats. When these bats make their nightly departure from the tubes, they put on quite a show—namely, the second largest bat flight in North America.

Braving a long, bumpy ride down many unmarked dirt roads, the staff and volunteers of Hawks Aloft finally made it to our home for the night, a patch of land near the opening of the tubes where we would be camping. As dusk settled over the landscape, the bats began their exit, and all throughout the night they continued. The impressive bat population in this area also means that there are a large number of raptors that feed on the bats, like Swainson’s Hawks.

There was plenty of life on the ground, as well, including other birds like roadrunners and quail.

Unique mammals abound throughout the vast property. We were lucky enough to see oryx, bison, fox, and bobcats.

In addition to the abundance of fauna on the Armendaris, there is a wealth of native plants including cottonwood, willow, and native grasses.  The untouched landscape provides a great habitat for threatened and endangered species, such as the bolson tortoise.

The Armendaris Ranch is a fantastic example of what it means to be effective stewards of the land, and provided us with a great example of well managed New Mexican habitat.
