I’ve been behind with stacks of papers to grade, and they’ve kept me from keeping up as often as I’d prefer. During the period from October 7–18, I conducted 8 surveys, skipping Oct. 8, 14, and 15. The data from these last 11 days look a bit like this:
Oct. 7: HOWR
Oct. 9: no casualties
Oct. 10: no casualties
Oct. 11: LISP
Oct. 12: TUTI
Oct. 13: no casualties
Oct. 16: OCWA, SOSP, LISP, and NAWA
Oct. 17: no casualties
Oct. 18: no casualties
Just past mid-October, and we are crushing the annual mortality count right now with 55 dead birds.
Oct. 7 – I found just the third House Wren on the project. This one ended up on a warm air outflow grate from the air conditioning unit and was quickly desiccated.
Oct. 11 – I collected this Lincoln’s Sparrow from the south portico.
Oct. 12 – This Tufted Titmouse was a surprise in the southwestern alcove.
Oct. 16 – This was not a good day for migrants. I found an Orange-crowned Warbler at the northeast alcove, a Song Sparrow at the south portico, and a Lincoln’s Sparrow at the southwestern alcove. Shortly after completing my survey, a Nashville Warbler was turned in from a collision in the southwestern alcove.
The current gap of collisions I’ve enjoyed over the past week or so was interrupted this morning by a beautiful male Nashville Warbler in the northeast alcove. He was an AHY bird with a fat score = 2 on my 3-point scale. This is the 11th Nashville Warbler I’ve found on the project.
That southwestern alcove continues to get a workout this fall, but again, the unfortunate victim was found in front of untreated glass panes.
Today it was a hatch-year (HY) Nashville Warbler; sex undetermined with fat score = 2.
When I found the bird in position on the cement as indicated in the above photo, it had already been heavily scavenged by ants. I moved the carcass to a location on the grass on the north side of this southwestern alcove (see photo, top right) to set up a removal trial.
I found this trapped Nashville Warbler today, chilly in the shade on a cool morning. It didn’t look too strong when I first approached it, but it immediately perked up and flew away when I tried to see if it could perch on a nearby oak branch.
Today I found a window-killed Nashville Warbler in the southwestern alcove. The brownish cast to the upperparts and tapered rectrices suggest a HY bird, sex undetermined. Fat = 2. I have included a radar image of last night’s flight on a rare evening that felt a lot more like October than September.
