Not-so-injured Western Screech-Owl
The phone rang late two nights ago. It was David B., one of our avian caretakers, who had driven right over a lump in the road, realizing at the last minute that it was an injured owl. He stopped, gathered up the bird, and was anxious to get medical care for the stunned owl. As I set about making calls to find the nearest person, he called back again. This time he reported that he didn't think there was anything wrong with this owl. Apparently when he got the owl home and was attempting to put it into a box, the owl wriggled free and led David on a merry chase throughout his house. Still, I knew that the owl would need to be examined by a wildlife rehabilitator prior to release to ensure there were no underlying problems. David and owl arrived at my home about an hour later, with the little screecher secured in a well-taped cardboard box.
All was well until about 5:30 a.m., when I gathered up little owl, huddled in the corner of his box to give life nourishing fluids. Same scenario: owl wriggles free, flies all over my house, and finally gets chased into the bathroom (where the kestrel sleeps at night). Whew! Owl seems fine to me too, but I know the drill. It's off to a rehabilitator for a better evaluation.
So, yesterday, I took little owl to the office where Kristin and Peggy are both wildlife rehabilitators (I am only an emergency back-up for the real thing - sort of like a bird EMT). Kristin drew the short straw and took Little Owl out of the carrier for evaluation. A strong sense of deja vu came over me. Sure enough, Little Owl wriggled free and was free-flying in our office, at one point perching atop the coat tree right in front of the photo of our educational screecher. Ron K. snapped this photo, and then it was off again. Did you know that a screecher can hang upside down from the ceiling tiles? Fortunately, we have large nets in our office for the precise purpose of catching injured birds.
In the case of Little Owl, the odds are excellent for release, probably within a day or two. However, it does graphically illustrate the power of an observant human. Had David not come upon Little Owl at that precise moment, the next car may have created road kill instead of saving a life! Thank you David!

Mexico, an Elder Statesman
One of the responsibilities that we have is providing the best possible care for our educational ambassadors. This includes being aware of any special care requirements for a particular species as well as the idiosyncracies of the different individuals. Such is the case with our elderly Mississippi Kite, whom we call Mexico, so named because the entire population flies south to Mexico, Central and South America for the winter. Mississippi Kites are insectivores that forage aerially for moths, grasshoppers, cicadas, flying ants and more. As the insects decline with the onset of cooler temperatures, so does the kite population. Mexico, already wearing adult plumage, arrived in 2000. This means that he is at least 11 years old now, the upper limit of a life span of a wild Mississippi Kite. He is not equipped to winter outdoors. During the fall as nighttime temperatures drop, he is only outside during mid-day, and by November he is a permanent indoor resident. However, he seems to take it all in stride and easily transitions to his indoor environment near a sunny window with several perches, a water pan, and food stump. In fact, he seems so comfortable that he spends much of the winter months courting his human companion and artfully arranging towels and stuffed toys in a nestful sort of way.

Raptors of the Rio Grande Gorge
This Golden Eagle nestling fledged prematurely. However, it still has a good chance of survival because of its large size, and because its parents will continue to provide care while it is on the ground.
Golden Eagles continue to add to existing nests for many years, eventually amassing a massive structure several feet tall and several feet wide.

There is a fissure, a crack of basalt that runs through north central New Mexico. In it lies a river, the hydrologic aorta of the state, the Rio Grande. Within this canyon nesting Golden Eagles thrive, along with Prairie Falcons, and Red-tailed Hawks. Commonly known as the Rio Grande Gorge, it contains some of the largest Golden Eagle nests that I have ever seen. Some of which attain heights nearing 10 feet, attesting to fact that Golden Eagles have been using these nest sites in the gorge for a very, very, long time.

Fall Songbird Migration - Albuquerque Bosque
MacGillivray's Warbler. Photo by Doug Brown.
Fall migration is now clearly in full swing. Large numbers of MacGillivray’s Warbler, Yellow Warbler, and Virginia’s Warbler are currently moving through the bosque. Wilson’s Warbler numbers are currently comparable to those of the three warblers mentioned above, but are small compared to the numbers that will be present in the bosque during the coming weeks. Orange-crown Warbler and Townsend’s Warbler are also moving through in relatively large numbers. Western Wood-Pewee numbers have greatly increased this week compared to earlier in the month. We undoubtedly undercount vireos in the bosque because they rarely vocalize during this time of year, but we have recorded three species so far this week. Warbling Vireos are regular right now, and we finally detected our first Plumbeous Vireos this week. Most exciting, however, is the detection of three Red-eyed Vireos over the past eight days, a species that is normally very rare in the bosque.

Songbird Migration Is On!
Migration is beginning to pick up steam in the bosque. Among warblers, Yellow Warblers are currently moving through in the largest numbers, with smaller numbers of MacGillivray’s Warblers and Virginia’s Warblers also popping up. Wilson’s Warblers are just starting to trickle into the bosque, and we have also recorded Black-throated Gray Warbler and Orange-crowned Warbler over the past week. Other migrants currently moving through include Western Tanager, Warbling Vireo, Rufous Hummingbird, Broad-tailed Hummingbird, Calliope Hummingbird, and Gray Flycatcher. Other species of note include Lark Sparrow and Chipping Sparrow, both of which are moving around in large numbers, the occasional Red-breasted Nuthatch, and increasing numbers of Bullock’s Oriole and Lazuli Bunting

Golden Eagle Nestlings
These Golden Eagle nestlings were filmed through a spotting scope by Hawks Aloft raptor biologist, Ron Kellermueller. The parents had just made a prey delivery as Ron and his son, Malcolm watched. Check out the size of this nest!
