Any use of a slash system will confuse. We get salvaged bird specimens from the Bahamas, which has more or less equal numbers of Brits and Americans, and many of these have something like 7/5/2020 written on the tags. I then have to figure out if it was a Brit or an American that wrote the...
In the second photo, it looks like the two birds in flight in the first have joined the two Pectorals (they are the second and fourth birds from the left). They are much smaller and rather plain backed. Could be either Semipalmated or Least Sandpiper, but I can't quite see the leg color or bill size
The current default feeder bird around here (Gainesville area), especially in pines, is Chipping Sparrow; I think this is probably one. Believe it or not, House Sparrows are very local here, either at the UF dairy unit, or at selected downtown parking garages and cafes.
One of the main reasons for the journal title changes was that journals named after birds put ornithologists at a decided disadvantage when they were compared against academics from other "-ologies" that have standard journal titles. Let's say there is a search for a new faculty member at a...
The wing looks like Swainson's Hawk, with 4 four fingers, pale underwing coverts and dark remiges. The tail looks like an adult Red-tail, the head and body like a leucistic Red-tail or Krider's Red-tail. Weird.
Bartram's records of "Vultur sacra" in Florida have been assessed by many (e.g., Howell 1932, AOU 1983, Robertson and Woolfendon 1992, Greenlaw et al. 2014) and interpreted as Crested Caracara (AOU1983) or even a "mythical species (Howell). Robertson and Woolfenden note that no fossils from King...
I think Bushtit. Head feathers are molting, making the bill look bigger. Wrentit has a longer tail, more brownish tones, and it would be quite unusual to pose vertically like this - they almost always are horizontal in posture and have their tail cocked up.
