[cobirds] Barr Lake CBC results

We held our Barr Lake CBC on Jan 2nd. It was a cold, foggy morning with limited visibility, but at least it wasn't snowing during the count! All things considered, we had a great day and were able to see plenty of birds despite the challenging weather (we couldn't even see Barr Lake for most of the count!). 
  • We had 23 participants divided among 9 groups.
  • We tallied 33,914 individual birds of 69 species. We average about 70 species so it was great to be right about at the average, despite the weather conditions.
  • About 75% of those individuals were Cackling or Canada Geese, or European Starlings, again pretty typical for this count circle.
  • We had one new species for the count circle, a Golden-crowned Sparrow!
  • We had an all-time high of 476 American Robin, more than the first 20 years of this count circle combined (1981-2000).
  • Raptors were low across the board, particularly Great Horned Owls with just one seen, tied for lowest (1991). This was likely driven by the low visibility than anything else.
  • We saw 72 Bald Eagles, considering the limited visibility this was higher than expected!
Thanks to all who participated in this count, we hope to see you again next year and we're always welcome to new participants as well!

Cheers,
