2011/12 REPORT
The 31st Annual Dunrobin (ON) - Breckenridge (QC) Christmas Bird Count took place on Thursday, December 29, 2011. A total of 35 field observers and 7 feeder watchers recorded 50 species and 8,430 individuals.
Weather Conditions:
A very cold day. If you were a polar bear you would have felt at home! With an overnight low of -19c the temperature dropped to -21c at dawn and a wind chill of -30c! Over the course of the day the temperature remained around -17c with a wind chill of -24c. The winds were mainly from the W for most of the day at 15 km and skies were partly cloudy.
A week earlier the Ottawa River was wide open but froze over just prior to the count. On the day of the count, a few some small creeks and storm sewer outlets were open in the Kanata North area and there were a couple of small opening on the Ottawa River. The cone crop was again poor over most of the count circle but there was still a good berry crop including Mountain Ash, Buckthorn, and Crab-apple.
Sunrise: 7:42 a.m.
Sunset: 4:27 p.m.
Species:
Despite the extreme cold and quiet start it was a fun day in the field. Like the past couple of years, not a lot of activity but definitely lots of interesting observations. Again, the few bird feeders that were full of seed had good concentrations of birds. The empty feeder syndrome continues in eastern Ontario? Not sure why!

There were no new
species found so both Boreal Owl and Northern Mockingbird are still likely
candidates for next year. A number of interesting
observations were made, including: Canada
Goose, Bald Eagle, Snowy Owl, Northern Saw-whet Owl and Brown-headed Cowbird.
New Species: No new
species and the overall total remains at 110 species.

I would like to thank the field observers and sector leaders for their great effort and my wife, Laurie, for preparing the wonderful post-count supper and to all participants who brought deserts, food and wine to celebrate the 31st anniversary!
The tentative date for the 32nd annual Dunrobin-Breckenridge CBC is Saturday, January 5, 2013, hope to see you there!
