Christmas Bird Count Results 2007

 

Fort Collins CBC

The 61st Fort Collins CBC was held Saturday, Dec 15. We tallied 91 species plus 5 others during count week. One new species was added: Trumpeter Swan. One regular species, Prairie Falcon, was noticeably absent, missed for the first time since 1971. Ironically, we had an all-time high count of 12 for this species in 2006!. New high counts were noted for Cackling Goose (4788), Virginia Rail (9), Eurasian Collared-Dove (792), Mountain Chickadee (164), Red-breasted Nuthatch (101) and American Robin (1782).

The rarest birds were:
Savannah Sparrow -1 during count week (0 previous years)
Trumpeter Swan-1 (0 previous yrs)
Northern Saw-Whet Owl-1 (2 previous yrs)
Rusty Blackbird-1 (2 prev. yrs)
Green-tailed Towhee-1 (3 prev. yrs)
Purple Finch -1 (4 prev yrs)
American Pipit -1 during count week (4 prev yrs)
Brown Thrasher -1 (5 prev yrs)
