Marathon CBC summary

On Sunday, December 20 about twenty five birders fanned out over the Marathon - Pic River - Heron Bay area during a very productive and enjoyable Christmas Bird Count. This was the 33rd year Marathon has participated in this international Citizen Science project since 1958.

The limited snow cover enabled bird-counting parties to access the bush without snowshoes or skis. On a trek to Sturdee Cove, Nick Escott and Brian Moore crossed paths with a Barred Owl (a count first) and a Townsend's Solitaire, a Rocky Mountain species which rarely strays into Ontario in the winter. On Hawk’s Ridge, Kyle and Christine Drake were rewarded with a Black-backed Woodpecker.

Thanks to the efforts of backyard feeder watchers, White-breasted Nuthatch, Northern Cardinal, Fox Sparrow and Eastern Towhee were tallied.

Some of the numbers
  • 38 species seen on count day (average 25.1, highest was 40 species in 2001)
  • total individuals: 1139 (average 1035)
  • high counts: Mourning Dove (33) (prev high 27 in 2007); Blue Jay (9) (prev high 5 in 2005)
  • Two new species for Count Day: Ring-necked Duck (1) and Barred Owl (1)
  • Townsend's Solitaire - 2nd ever for count (first in 1988)
  • Eastern Towhee (a single bird for the 6th year)
  • Fox Sparrow - 2nd ever for count (first in 2007)
  • Chipping Sparrow - new species for count week
