Flammulated Owl Revelations

“After hearing a female Flammulated Owl on Oso Ridge in 1996 while conducting a Spotted Owl survey, I returned to look for nest sites and found three Flammulated Owl nests in the first three cavities I checked!” David Arsenault explained of one of his first encounters with the small raptor. After that, he was hooked. For eleven years in a row he banded hundreds of Flammulated Owls each season on Oso Ridge, learning about their movements and territoriality. David has transferred his interest in the petite owl to his work for the Plumas Audubon Society in Northern California, where he employs a variety of strategies to learn about the secret life of the species.

The Flammulated Owl is the second smallest owl in North America, after the Elf Owl. These dark-eyed raptors breed in montane forests in western North America before traveling to Mexico to winter. Secretive and quiet, especially when a human is detected in the area, Flammulated Owls were once thought to be rare. Improved research strategies, however, have indicated they are common, though populations are declining overall.

Since that fateful encounter 20 years ago, David has sought to study the migration patterns of these neotropical migrants with geolocators, genetics, and mark-recapture, as well as resolve questions around mate fidelity, nest site selection and distribution, the impact and use of nest boxes, and the varied effects of forest thinning on Flammulated Owl populations.

David spent a considerable amount of time in New Mexico, studying Flammulated Owls and other bird species for Hawks Aloft. Despite the fact that most of his work is in California these days, it recently took him to the Zuni Mountains in northwestern New Mexico, and he invited Hawks Aloft volunteer and photographer-extraordinaire, Larry Rimer to tag along and encounter this rarely photographed bird. “Other than the almost impassable dirt roads (even [when] dry) and the countless bug bites, it was fantastic,” Larry said about his experience, expounding on the mixed forests and the solitude of these rarely visited mountains.

From 9 a.m. to 5 p.m. every day, the research group—which included university students, as well—checked known cavities and nest boxes, while searching for other possible nesting sites. The group averaged about ten miles on foot daily. Just before nightfall, the group would head out again, setting up mist nets to capture the owls and gather data—their weight, wing size, sex, etc.—before banding and re-releasing them.

The trip was a success. “Usually in California, they manage to capture three birds in three weeks,” Larry said. “Here we managed to capture 15 owls in 4 days.” This bodes well for David’s research. “I was concerned that more cavities were being lost to fallen trees and branches each year than were being created by Woodpeckers, so I put up … nest boxes,” David explained. Noting the success of the nest boxes he put up in New Mexico, he continued the project in California, where many were taken over by flying squirrels, but are utilized by Flammulated Owls as well.

In addition to the measureable success of the nest boxes, David’s research has also illuminated the migratory habits of these secretive birds—one of the geolocators fixed to an owl in northern California tracked the bird as far south as Jalisco, Mexico. The research that David is spearheading on the Flammulated Owl isn’t just providing new insights into how they live, but providing rewarding experiences for those who work with the birds, as Larry said, “This was a once in a lifetime learning experience. [I] feel so very lucky to have been allowed to be a part of it.”

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.”

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.

Young Northern Harriers

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.

Saving the Black-necked Stilt, a U.S. International Boundary Water Commission Endeavor

Sometimes, or perhaps always, work projects do not proceed as planned. Such was the case in the lower Rio Grande near Anapra, New Mexico, where the U.S. International Boundary Water Commission (USIBWC) was performing maintenance operations to remove sediment accumulation in the river channel in front of an agricultural return drain. Operations underway the week of May 5, 2014 created a large island of sediment scooped up by heavy machinery. A surprise was in store for the crew when they returned to work on Monday, May 12. Apparently Black-necked Stilts found this barren patch of earth to their liking and set up nests over the weekend with eggs already present.

The Black-necked Stilt, a long-legged, strikingly black and white wading bird, nests on the ground. They tend to build above the water line on small islands, clumps of vegetation, or even, occasionally, floating mats of algae. Both females and males choose the site and trade off the nest construction duties; they look for places with soft substrate that can be scraped away to form the depression in which they nest. While one mate observes, the other scrapes into the dirt with breast and feet to form a depression about 2” deep. As they dig, they throw small bits of lining over their back into the nest, consisting of whatever material is closest to the nest, including grasses, shells, mud chips, pebbles, and bones.

Back at the International Boundary Water Commission construction site, field crews surveyed the area and located some eggs on a large island of sediment that was being used to dredge out the channel. Three nests with a total of nine eggs had been documented by their environmental staff. The area was flagged and avoided. They contacted Hawks Aloft for recommendations, and we urged them to try to work around the nests. With a presumed egg-laying of May 10 or 11, hatch would be expected at about May 24 or 25.

This issue was further complicated by plans to release water from Elephant Butte dam for the purpose of irrigation beginning on May 25, 2014. Because the logistics of any attempt to change the irrigation releases would have required multiple agency approvals that would affect planned crop irrigation in the surrounding valley, it seemed impossible to achieve. Once water releases occurred, it was probable that the nests would be inundated, killing the embryos or nestlings not yet mobile enough to escape the rising water.

The maintenance staff at the USIBWC established and maintained a buffer around the nesting site. The nesting stilts did not appear to be disturbed by the heavy equipment in the area but aggressively defended their nests when environmental staff came to monitor the nest sites. The big question; however, remained: Would the eggs hatch soon enough to allow the young to survive? It would be close!

On Thursday, May 22, 2014, ten Black-necked Stilt chicks were observed.  The two nests of four eggs had hatched. It was clear that there must have been an additional nest located near the project area.

No work was conducted in the area over Memorial Day weekend, and water was released on schedule from the Elephant Butte dam on Sunday the 25th.  On Tuesday the 27th, two chicks and adults were still observed near the project site in the morning, but all Black-necked Stilts had moved out of the project area by the afternoon.  Disaster averted!

We thank the USIBWC for proactively protecting these nests by mounding soil to divert water flows away from the nest sites and for establishing and maintaining buffer zones that enabled these Black-necked Stilts to produce young in 2014. We thank Rebecca Little Owl and Albert Flores, Environmental Protection Specialists, for their efforts to protect these nests and working collaboratively with Hawks Aloft to develop a mitigation plan.

Mom & Dad Know What They Are Doing

Written by Lisa Morgan, Raptor Rescue Coordinator.

On June 7, we received a call from a retirement community in Rio Rancho about FIVE Cooper’s Hawk chicks that had been blown out of a nest high in a cottonwood tree. Two chicks survived the fall. We determined that the best option was to return the chicks to the cottonwood tree where their parents could continue caring for them – even though we could never locate the nest.

With the help of PNM Resources, and their tree climbing crew, Trees, Inc., we set about making an artificial nest in the tree from whence they came.  The crew first installed a human-constructed nest consisting of a wicker basket and natural nest lining materials.

Once the nest was thoroughly secured in the tree, it was time to hoist the nestlings back up and into their new home, where their parents still waited even though it had been four days since the chicks were taken.

The two chicks settled right into their human-constructed nest, just as if they had always been there.  Dad Cooper’s Hawk even attempted to deliver food to his chicks while all this was in progress, although he was frightened off by all the commotion.

The biggest issue we contended with was  concerned citizens that continued trying to come to the aid of these chicks, disturbing their parents’ attempts to care for them.
In the end, it was a successful return once we were able to educate the neighbors about the privacy needs of the hawk family. Although it can be difficult to watch these youngsters on the ground, in nearly all cases it best to allow the families to stay together and the parents to continue caring for their youngsters.

Through the Eyes of an Intern, No. 2: What pine tree? Which clump?

And we're off!

And we’re off!

Well. So much has happened since my last post that I don’t even know where to start. I had my first real field work experience with Dave Parsons, a volunteer, and Jennifer Goyette, our very cool new biologist, three Thursdays ago, and I was planning to write about that. Then I had my first REAL field work experience a week ago, in the Gila National Forest. I spent the time with Mike Fugagli, one of our avian biologists, searching for Mexican Spotted Owl fledglings. Yes, I saw impressive adult owls and adorable baby owls. Yes, I camped in the car and didn’t shower for three days. And, yes, I got the notice to travel, packed up the car with food and camping gear, and drove six hours to a place I’d never been before within one day. I am slightly proud of myself, especially considering that this was my first long-distance solo road trip.

I loved this trip! If all field work were like this, I’d want to do it all the time. There’s something spectacular about being out on the open road: seeing everything on the side of the road from pink-flowered chollas in full bloom to huge solar panel arrays, watching birds (swallows maybe?) swoop in spectacular displays and almost hit my windshield, and feeling this delicious tension between full-throated adventure and “oh, goodness, will I ever find this mysterious campground?”. Sleeping with stars overhead and no lights around is amazing. The endless plains of grass and shrubs and rocks and hills to either side of the road; the huge sky, bright sun, and playful clouds above; they were ridiculously refreshing to me after eight months in cold cold, grey, close-set-forest of Massachusetts. Ahh, New Mexico. But I digress. I know very well that you all were expecting to read something about birds, not just my ramblings about driving on the highway (which starts to sound too much like a country song to me), so here you go:

Mike taking pictures of the first owl, the father of a nestling or two who hadn’t yet fledged (left the nest). Still, though, he looks pretty happy, so I’m guessing everything is going well with his kids!

This was the first Spotted Owl we spotted and, through some stroke of luck, I saw him before Mike. Lucky because that man is quite honestly one of the best bird identifiers and trackers I’ve ever met, and I feel so privileged to be able to work with him! Just sitting around the camp table on the first morning, drinking some cowboy coffee and watching the wildlife around us, he was able to identify at least four different bird species by either sight or call and show me two different nests right next to our campsite. Can I be like him when I grow up, please?

We visited six nest sites, five of which had owls present. Four of those had fledglings, including two with two fledglings! This is actually very important because Mexican Spotted Owls are listed as threatened by the Fish and Wildlife Service and two fledglings are much harder to raise than just one. As Mike put it, it’s kind of like raising a cottonwood tree: easy at first because it grows quickly, nearly impossible to keep it going once it has a 30-foot diameter canopy since it has to be watered at the drip line, which is where the canopy ends—sort of an exponential increase in necessary inputs to get the same output/a not-dead tree in your yard. But back to owls: finding these guys—whether the adults, the fledglings, or especially their nest—was quite challenging. The title of this blog comes from the second-to-last site we checked, when Mike said that the nest was “a clump in that pine tree” and, naturally, there were about twenty such combinations in the direction he pointed. It was always rewarding when at last feathers materialized from bark and I could actually distinguish the owl. Probably my favorite memory is when I saw my first fledgling, or, as I like to call them, puffballs. There’s really no better way to describe these absolutely adorable young owls.

Fitting that a Capricorn (mountain goat) should try to scramble up this hill. This and its brethren had a greater than 30° incline in some places and I am most definitely counting them as sufficient cardio for the next two or three weeks.

I was pretty sad that this trip was so short, despite climbing ridiculous hills and dealing with ever-present bugs and access roads that would be politely described as “extremely potholed.” But I’ll always keep the memory of this very first field work trip, and the best part is, I still have several weeks left of field work, including one next week to the Valles Caldera with Jennifer. I’ll write about that next time! Until then, happy trails.

Super Mom!

Our educational Swainson’s Hawk, Hudder is the world’s best foster mother! Every year she builds a nest and lays two infertile eggs.  And she sits patiently on them until Gail removes them about 2 months later, just KNOWING that chicks will come.  Once the eggs are gone, she wails because there are no babies.  But, some years she gets to be a foster mother, and she is the best mom ever!

This year, she fostered three Swainson’s Hawks chicks. All three came to Hawks Aloft from The Santa Fe Raptor Center.  They were found in southern New Mexico.  All were orphans, probably victims of the drought.  Nest failure has been high this year and it’s believed to be because of the drought. Prey numbers of all types are down, including grasshoppers and small mammals favored by Swainson’s Hawks.

Hud feeding chick  7-10-13

Hudder started to care for chick #1 from almost the first minute that he was placed in her flight cage.  She fed him 5 mice for his first meal.  He was hungry! She was hyper vigilant in watching over his safety and making sure he ate well.

Hud and Chick 1

Chicks # 2 and 3 came to Hudder later in July. She was just as good a foster mother with them. Chick #2 had a problem with a cloudy eye, so his human foster parents watched him closely too. Chick #3 was able to self feed from the beginning, swallowing mice whole, but Hudder tried to help feed him anyway.

Hud and Family

All three chicks became part of the family group. Now that the chicks are older, they are back in Santa Fe attending mouse school. They seem to be doing very well, even chick #2 is learning to hunt for himself. We hope they will be released this fall in southern New Mexico.

Hudder was rescued herself in 1989, making her 24 years old, our oldest educational ambassador.   We don’t know much about what happened to her before she arrived here.  Likely, she may have been hit by a car.  Her left pupil is fixed and her right wing is damaged.  But that doesn’t stop her from being a Super Mom and a great educational bird too.

Nest Monitoring at New Mexico Tech

I don’t know what we’d do at Hawks Aloft without our many wonderful volunteers.  One such volunteer is Vicky Gonzales.  Vicky has been monitoring this Cooper’s Hawk nest on the campus of New Mexico Institute of Mining and Technology in Socorro NM, south of Albuquerque. This nest produced three fledglings.  In the photo below, one is visible in the nest.

babies - new bird (4)At the time these images were taken by Vicky, two of the chicks had branched.  Also called ‘branchers’ this refers to the time period when the young have climbed out of the nest and onto nearby branches in the same tree, but are not yet flighted.NMMT nest  with two fledglings

In the image below, one of the parents stands guard.  Adults wear distinctly different plumage than juveniles.  They have a horizontal rufous barring on their breasts and dark, solid gray backs.  Eye color in Cooper’s Hawks, and all accipiters, changes over time, from blue-eyed babies whose eyes become yellow by the time they are six months old, to the dark red of older adults.  Although it is tempting to try to determine the age of an accipiter by its eye color, the rate of eye color change is variable and can’t reliably be used as an age indicator.

NMMT nest parent

The bird shown below is a visitor to the nest, and not one of the parents.  If you look closely at this bird you will notice a combination of the vertical streaking characteristic of a juvenile and also the rufous barring of the adults.  It also has a yellow eye.  Thus, we can say with confidence that this bird was hatched in 2012.  Perhaps it was one of the fledglings from that year’s nest that is still tolerated by its parents.

NMMT nest visitor

Cooper’s Hawks are found in wooded areas, from dense forests to suburban backyards.  They sometimes show up at backyard feeders, looking for an easy meal – but not sunflower seeds.  They have adapted to city life in their pursuit of Rock Pigeons and other small birds to eat.

Many thanks, Vicky, for monitoring the nest and for your wonderful images of these beautiful birds.

Hot, Dry Summer

by Trevor Fetz, Lead Avian Biologist

June brought the beginning of the summer field season for the Middle Rio Grande Songbird Study.  It was a hot, dry month in the bosque.  Bird numbers were lower than normal at most sites and across most species during June.  A particularly disturbing trend seems to be playing out with Black-headed Grosbeaks in the bosque. Up until the past few years, this was one of the more common bosque species during summer. Numbers have steadily declined over the past few years, but the bottom seems to have fallen out this year.  It is difficult to pinpoint the causes of the reduction in Black-headed Grosbeaks, but the ongoing drought conditions in New Mexico are certainly not helping.

Black Headed Grosbeak

A noteworthy detection in June was the confirmation of Virginia Rail breeding in the marsh at La Joya Game Management Area. Although we have recorded Virginia Rail at our marsh transects, we have never been certain that the species breeds there. But, on a mid-June visit I observed an adult rail and six little black fuzz-balls foraging in the mud. The adult immediately gave an alarm call and the fuzz-balls scurried into the dense cattails.

The steadily dropping water level in the marsh has led to an increase in rail detections. As the water level has dropped, the rails have been forced to come out into the open to reach the remaining pools for foraging.  Unfortunately, the marsh is likely to be completely dry within the next couple of weeks.  It looks like most of the hatch-year rails will soon be flighted. But the question is, where will they go? Suitable habitat is becoming increasingly scarce as conditions become increasingly dry throughout the middle Rio Grande.

Birds are not the only creatures to suffer from the drought. For many species, the drought causes a decline in the food supply, which can result in a corresponding increase in mortality, especially of the young.  It also can drive animals into cities in search of food.  Let us hope that the recent July rains are an indication of a good monsoon season this year.

Its a Heat Wave!

Owlet1This little fellow showed up laying in the shade on a damp lawn one day, in the back yard of Rich M., a Phoenix resident.  It’s HOT there!  Through a friend, he contacted  Chellye Porter, worried about the health of this recently fledged owlet.  So, Chellye called us.  Our thoughts ran to HEAT stress.  We suggested that the owlet might just be trying to keep cool.

 

Sure enough, every night the little fellow disappeared only to show up again in the rising heat the next day.  This went on for about 10 days and then the owlet moved on, apparently not in need of the cooling properties of shade and grass.  He has been seen roosting in a tree in the neighborhood, and occasionally returns to the cool grass.  Thanks to Chellye for sharing the story and to Rich M. for the image.  Clever owlet!
