The four sparrows I found this morning might mark the deadliest evening I’ve seen in three years of searches at the Noble Research Center. I found birds on three sides of the building after a cool and rainy night. The first was a bedraggled Lincoln’s Sparrow (fat = 2) that I left in place for a check on scavenging rate. Elsewhere, I collected these three Grasshopper Sparrows. The two dry ones on the left were a few feet from each other on the south side of the building, the wet one on the right was in one of the west alcoves.
I aged all three as AHY and all were fat: 3, 3, and 2 from left to right. Interesting to see the variability in dimensions of these birds, however. Numbered 1, 2, and 3 from left to right, check it out:
1: 20.5 g, bill 10.6, wing 60, tarsus 23.2
2: 16.5 g, bill 9.2, wing 58, tarsus 21.5
3: 18.0 g, bill 10.4, wing 64, tarsus 22.8
