7–18 October 2017 – all kinds of stuff

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.

10 May 2017 – Painted Bunting and Nashville Warbler

Today I found a SY Painted Bunting at the main north entrance and a Nashville Warbler at the northwestern alcove.

19 April 2017 – Nashville Warbler

This one was twofold odd – the bird was found in an odd spot and I’ve clearly overlooked it for a few days given the state of decomposition.  The beetles, slugs, etc. were all over it.

9 October 2016 – Nashville Warbler

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.

19 September 2016 – Nashville Warbler

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.

10 October 2015 – trapped Nashville Warbler

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.

13 September 2015 – Nashville Warbler

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.
