The 51st Black Forest CBC, held on Jan. 2, recorded 40 species and 1,635 individual birds. Average number of the 51 counts: 35 species and 1608 birds. We had 21 observers in 8 parties, plus 7 feeder-watchers. I don't detect much of a pattern of high and low counts. We found fewer than average of some ponderosa species -- 49 Mtn. Chickadees (ave. 64) and 75 Pygmy Nuthatches (ave. 89), but more Steller's Jays (57 vs. 30). The 24 Red-tailed Hawks way above the average 10, but 7 Rough-leggeds cf. 10 average.
Two invasive species dropped: Starling 94 (ave. 143); House Sparrow (2 vs. 23). Two increased: Rock Pigeon 74 vs. 25, Eur. Collared-Dove 32 vs. 6.
