CA/AZ: Red-tailed Hawks of Arizona

Image
We have things easy in the east. I'm no expert on western Red-tails, but while in the southwest I saw a wide range of Red-tail plumages, from light to rufous to dark. I was able to get photos of a few of the birds and figured I would post them here, from light to dark. I saw much more variation than this, but these were the only ones I photographed. Western buteo ID is something I could get into someday, particularly with future visits, but right now I just don't have the time... - NB

CA/AZ: Juncos of Arizona

Image
During my Arizona birding I spent some time studying the junco flocks. It's not something I planned on doing much of, but once I began to sort through the first flock I was hooked. I'm pretty sure my time spent on Dark-eyed Juncos cost me a life bird or two along the way. As of right now we have two species of junco in the U.S., both of which occur in Arizona: Dark-eyed (with several subspecies) and Yellow-eyed. This current taxonomic breakdown is a bit controversial among birders. To get an idea about the junco situation, if you are not already aware, check out the ID-Frontiers discussion from a few years ago, sparked by Mark Szantyr and his photos from Connecticut. In Arizona I observed Yellow-eyed Juncos plus the following forms of Dark-eyed Junco: Oregon, Pink-sided, Gray-headed, Red-backed, and "Cassiar." Cassiar Juncos are intermediate between Oregon of the west and Slate-colored of the east. I'll post images here, form-by-form. Interestingly, of the dozen...

CA/AZ: Day 9 (Feb 23) - eastern Chiricahua Mtns and Sulphur Springs Valley

Image
I woke up to 27 degree temps and ice on the car windows. Yesterday's snow levels were above 5500 feet. Willcox itself sits at 4100 ft, so it received only rain. I was worried about black ice on the roads but the puddles had apparently dried up before the temps dropped...gotta love that dry Arizona air. It was a 2-hour drive to the tiny "town" of Portal. I arrived just before sunup at Big Thicket, just outside Portal, which is known to harbor Crissal Thrashers. Chiricahua Mountains had to cross into New Mexico to get to Portal A local guide and birder named Dave Jasper lives adjacent to the Big Thicket, and his feeders sometimes attract the stealthy Crissal Thrasher into the open to feed. When I arrived the temp had only climbed one degree, and the lack of song indicated that the birds were taking some time to get active. hey, that's gotta be a good sign After only a few minutes at his feeders, what hopped out of the bushes but a CRISSAL THRASHER, followed by a second ...
