Song Sparrow finally gone. It sat untouched for 20 days.
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.
As I’m about to head out for a conference this week, spring and summer monitoring comes to a close. I’ll begin August 2017 the 9th consecutive year of (mostly) daily monitoring for window casualties at the Noble Research Center on the campus of Oklahoma State University in Stillwater, Oklahoma, USA.
It’s been a busy spring.
Beginning Mar 1st, here’s what has turned up at the Noble Research Center.
- Indigo Bunting – 5
- Painted Bunting – 5
- Ruby-throated Hummingbird – 3
- Lincoln’s Sparrow – 2
- Mourning Dove – 2
- Nashville Warbler – 2
- Orange-crowned Warbler – 2
- Baltimore Oriole – 1
- Chipping Sparrow – 1
- Eastern Meadowlark – 1
- House Wren – 1
- Northern Parula – 1
- Tennessee Warbler – 1
- Yellow-billed Cuckoo – 1
That’s 28 individuals of 14 species, and damn, that is disheartening.
On the plus side, my commitment to checking almost every day has put me in position to save a few birds by getting them safely away from the building and taking them someplace secure to rest and recuperate for a bit. I can’t guarantee that all 6 of these survived the ordeal, but they seemed to be in good shape when I last saw them:
- Northern Cardinal
- Common Yellowthroat
- Mourning Dove
- Song Sparrow
- Yellow Warbler
- Carolina Wren
No casualties yet, but I’m up to the 3rd trapped bird of the new year: a Song Sparrow in the northwest alcove. This one was stunned – or exhausted – but before I could get any closer than about 3m it flew away strongly – good sign!
This bird was likely riding a wave of migration that really lit up the radar last night (as linked from Paul Hurtado’s birding page). Check out the big blue blobs in Oklahoma from a little after 11 pm last night:
Keep your eye on that slug of rain and storms (the green, yellow, and red) in the OK Panhandle, though.
Now check out the line of rain and storms that moved in overnight and set up shop on the Kansas border. This is from a bit before 6:00 am, and nobody moving north through our state kept on moving through that! This is a classic setup for a “fallout” of birds. More storms today followed by strong north winds tomorrow will likely keep some staging migrants around for a few more days.
This one, evidently collided and cat-scavenged, presented an identification challenge. The remaining feathers strongly suggested Melospiza sparrow, but it was really the pattern on the undertail coverts and other contour feathers that provided the necessary clues as to which one. Ultimately, the black centers in a dark brown band on a lighter feather are congruent with Song Sparrow, but not Lincoln’s.
