CBCs began in New York City in 1900 and have continued ever since. On one day between December 14th and January 5th, participants go into the field and try to count all birds of all species in a 24km (15 mi.) diameter circle. The Hamilton circle, centered on Dundurn Castle, as shown below, is divided up into a large number of small areas. Hamilton's first CBC was in 1921. In Hamilton, it usually takes place on Boxing Day, Dec. 26th. Hamilton Christmas Bird Count Circle.

Whether you are a veteran of many CBCs or someone new to birding, the CBC always needs counters. The more people in the field the better a picture of Hamilton area bird life we can capture on Count Day. There is also an opportunity for people who know their birds but cannot get out into the field to assist with the CBC by recording birds seen at their feeders. To help as a Feederwatcher you must live inside the circle - click on the image to the right to see if your feeder(s) is/are in the circle.

2007 Hamilton Christmas Bird Count Summary

Count Day: December 26, 2007

On a cool - 4 degrees C, relatively calm but foggy morning, 88 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 - 2 degrees C. There was hoar frost on the pines and the tall weeds, and it was tricky underfoot on some of the woodland trails. In parts of the outlying areas, it was too foggy to see birds in flight. At the lake, counters had difficulty determining the numbers of ducks, as they were scattered over the lake, with many too far out to be counted and identified.

The total of birds counted was 64,054 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 count record now stands at 103.

It is obvious that many of the common woodland and garden species are becoming even more common, with new record counts for the following species:

SpeciesOld RecordNew Record
Mourning Dove1,5072,052
Black-capped Chickadee2,1092228
Northern Cardinal598672
Red-breasted Nuthatch8198
American Goldfinch1,0051,082
Red-bellied Woodpecker3347
Downy Woodpecker288323

The number of Hoary Redpolls counted this year ( 5 ) broke the old record of ( 1 ) set in 1993.

On the lake and inland waters we broke count records for the following:
