All right, it’s been several days so I’m comfortable listing that Lincoln’s Sparrow as trapped. It’s still in fine shape, but I watched it bump a window (gently) as it tried to evade me. There were at least two others and I think a Nashville Warbler hanging out in the trees by the main north entrance to the NRC this morning. It could be there are 4 trapped birds there, but I’m being conservative about how I catalog them because they are all flying strongly, etc.
Not so lucky were three other sparrows this morning. I found a Lincoln’s Sparrow at the southeast alcove and a Lincoln’s and Song Sparrow together at the south portico. All were in great shape with fat = 2 or 3. The Lincoln’s were both hatch-year; the Song was after hatch-year.
