The Rockford CBC was conducted on Saturday, December 17. 35 field observers participated in 15-18 parties, with 11 more at feeders. There were 73 species recorded, which is about 5 over the 10 year average and 25,412 total individuals. I have not yet posted to the Audubon CBC site because they have not completed their work to upgrade the site with the new data entry program. Keith McMullen described the problems he had yesterday on IBET.
Highlights of the Rockford count were, of course, 8 Red Crossbills, 3 White-winged Crossbills, a record number of Pine Siskins, and 1 Evening Grosbeak! We also had a few more species of waterfowl than average, such as Mute Swan (3), Ring-necked Duck, Gadwall, Ruddy Duck and Am. Coot, a Ross’ Goose. 6 Sandhill Cranes at Nygren Wetland Preserve were a new species to the count (count week previously). The moderate late fall temperatures kept some of the still water open, accounting for the waterfowl, plus a light snowfall overnight Friday and into Saturday morning moved some of the field birds toward the roadside and feeders. Good numbers of Horned Larks were counted, plus 444 Lapland Longspurs (345 in one flock) and a handful of Snow Buntings. Single Rusty and Brewer’s Blackbirds were highlights.
Lowlights were ZERO Ring-necked Pheasants!! Last year the count recorded 27, which was a low number, but ZERO? Habitat loss is almost certainly the primary blame for the plummeting decline of this species around here. Fence lines and hedgerows are disappearing rapidly for expanded agriculture planting, and CRP grassland contracts are expiring and not being renewed. So, the predators have a larger advantage on taking the remaining birds. Other misses were Golden-crowned Kinglet, Carolina Wren (last winter was tough on them) Field, Fox and Savannah Sparrows, and Red-winged Blackbird.
No Eurasian Collared-doves were recorded (still not seen on a Rockford CBC) although there is a flock of them in Ogle County just S of the Winnebago County line, but not near NW Winnebago County, where the count circle lies. Kishwaukee CBC ought to get them this year. No unusual owls or gulls were seen.
In contrast to 2010-11, the crop of fruits on Hackberry Trees was much reduced, so Cedar Waxwing and American Robin numbers were substantially lower than last year, but E. Bluebirds set a new count high with 38.
