Hello, Here are the preliminary results of the 2007 Hamilton Christmas Bird Count, held on December 26th. 2007. On a cool -4 degrees C, relatively calm but foggy morning, 85 participants set out to count birds in the field, at the lake, or at their birdfeeders. The temperature settled in for most of the day at -2 degrees C. There was a hint of hoar frost on the pines and the tall weeds, and it was tricky underfoot on some of the woodland trails. In some of the outlying areas it was too foggy to see or identify birds in flight, and on the lake, counters had difficulty determining the number of ducks that were scattered over the lake, with many too far out, and at the limits of the counters ability to identify them. The total number of birds counted was 63,046, which is below the last ten year average of 70,228. Thanks to the influx of some of the northern finches, we broke the old individual species count record of 102 set in 2004, by one, so the new individual species count record now stands at 103. It also appears that the common woodland and garden species are becoming even more common with new record counts for the following species....... Old Record New Record Mourning Dove 1,507 2,040 Black-capped Chickadee 2,109 2,223 Northern Cardinal 598 661 Red-breasted Nuthatch 81 97 American Goldfinch 1,005 1,055 Red-bellied Woodpecker 33 46 Downy Woodpecker 288 316 The number of Hoary Redpolls counted this year ( 5 ) broke the old record of ( 1 ) seen in 1993.
