I found a trapped Grasshopper Sparrow at the main North entrance to the NRC today, and then a second dead bird at the southeastern alcove. The trapped bird took quite a bit of effort to eventually guide away from the building, but the time was worth it if I was able to keep it from ending up like its comrade.
I shooed a Lincoln’s Sparrow from a corner at the southwestern alcove this morning. Again, it was in front of an untreated window pane. Of course, I don’t know where it might have been before I found it; I can only report where it is when I do.
Flight calls abounded last night as I walked the dog at least thrice. Those calls – little tsips! and tseeps! sounded to me like sparrows flowing from the north after three straight days of strong winds blowing from the south. A quick check of Paul Hurtado’s Nexrad radar birds page confirmed a big push in Midwest and the Plains:
Sadly, with that push came two casualties at the Noble Research Center: a Lincoln’s Sparrow (AHY-U with fat = 2) at the southwest alcove and a Common Yellowthroat (AHY-M with fat = 2) at the northwest alcove. (Apologies for the shaky portrait on the Yellowthroat – it looked clear on my phone.)
Although casualties continue to pile up in the west alcoves where I’ve treated several windows with ABC Bird Tape, it has so far appeared to be the untreated panes in those alcoves that are claiming the casualties.
Today I found a stunned Lincoln’s Sparrow on the south portico (no photo).
The bird couldn’t fly well, but it could fly. I decided to give it the “perch test” to determine if I should consider it to be a casualty or simply a trapped bird. Once able to catch it, I walked the bird south toward Edmond Low Library and found it a dense and secluded place to perch and rest where it might feel protected – or at least better protected than out in the open of the portico. I was pleased to see that the bird grasped a branch strongly and seemed to perch well. This one had me on the fence a bit, but I ultimately logged it as trapped. Though stunned, it seemed otherwise healthy with fat score = 2.
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.
