2004 Christmas Bird Count

The 2004 Hamilton Christmas Bird Count was again very successful, with a new overall count day record set. A grand total of 59,486 birds of 102 species were seen on Dec. 26, 2004, the highest ever species total for Count Day, beating the previous record of 101 attained in 2003.

Four other species were seen Dec. 23-25 or 27-29 but not on Dec. 26, bringing the 2004 Count Day plus Count Week total to 106, less than the 109 total in 2003 but above the previous high of 103 in 2002 and 1997. With heavy snow and freezing rain several days before the count, there is no doubt that the species record resulted from the hard work of the 103 participants. Further illustrating the need to have as many participants as possible, 25 of the species seen on Count Day were found in only one area, while another 16 species were seen in only two areas.

Weather: 3AM-6AM – Overcast, southwest winds 15 kmph, low temperature -12C. 6AM – noon – clear skies, winds west 15 kmph. Noon-3PM – winds north 20kmph, gusting to 40kmph, hard driving snow in most areas. High temperature for the day was -7C. At least six to eight inches of snow on the ground throughout the region, most of it very hard due to rain a few days before the count, led to a significant drop in CBC counter walking hours for the 2004 count. Land birds were hard to find in some areas. Valley Inn and the water to Carroll’s Point were frozen but Hamilton Harbour and Burlington Bay were mainly ice free. Creeks were flowing freely but Cootes Paradise was completely iced over. Large numbers of lake ducks seen a week earlier and later were probably well offshore due to the winds.

Activity: 103 participants; 44 Field parties; 9 Owling parties; 13 Feederwatch reports. 134.5 hours walking (daytime); 69.2 hours driving (daytime); 13.25 hours owling; 58.5 hours feederwatching; 185.5 km walked daytime; 1211 km driven daytime; 202.2 km driven owling; 2 km walked owling.

New species for the count: none

Totals for 66 species were higher than the 10-year average (1994-2003). Totals significantly higher (double or more) in 2004 than the average for the previous 10 years were: Double-crested Cormorant*, Black-crowned Night-Heron, Trumpeter Swan*, Canada Goose, Snow Goose, White-winged Scoter*, Northern Harrier, Bald Eagle*, Rough-legged Hawk, Peregrine Falcon*; Wild Turkey*, Iceland Gull*; Lesser Black-backed Gull; Common Raven*, Carolina Wren, Field Sparrow, White-crowned Sparrow* and Pine Grosbeak. Species marked with an * reached new highs for the last fifty years of the count (1954-2003), as did Hooded Merganser and Eastern Screech Owl.

Species with totals significantly lower (half or less) in 2004 than the average for the previous 10 years (1994-2004) were: American Kestrel, Northern Flicker, American Robin, European Starling, Cedar Waxwing, Brown-headed Cowbird and Common Redpoll.

Other highlights: Blue Jay and Black-capped Chickadee totals were close to their ten-year averages (1994-2003). Canada Goose numbers recovered over the 2003 total. The continuing drop in numbers of European Starlings is partly explained by a pair of Peregrine Falcons having taken up residence in one of their regular roosting areas.

Long-time Hamilton birders have noted that in the 1950-60 period American Crows were not at all common in the Hamilton area during winter. The recent drops in crow numbers may be explained by the significant replacement of corn by soy beans by farmers in the Hamilton region, and also by the much lower number of open garbage dumps.
