[cobirds] Denver CBC Results (Denver, Jefferson, Douglas, Arapahoe Counties)

A great turnout in participants this year helped us reach an initial tally of 104 species!  One count area (of 23 in the field) has not yet reported and there are a number of Feeder Watchers that will be submitting their reports in the days ahead, so the total may rise a species or two.

 

THANK YOU to everyone that brought main dishes, drink, snacks and desserts to the great potluck compilation meeting! 

 

Highlights for the day were:

 

Hermit Thrush - 1 @ Chatfield (seen on only 5 of the past 61 prior counts)

Bonaparte's Gull - 1 @ Chatfield (only the second time record on the Denver CBC)

WHITE-WINGED SCOTER - 1 McClellan Reservoir -(Seen on only 5 prior counts)

     This bird seems to have moved the prior night (day?) from South Platte Park Reservoir to McClellan Reservoir (just east of Santa Fe on County Line Road)

Lesser Goldfinch - multiple reports (seen on 11 prior counts)

Green-tailed Towhee - 1 (seen on 12 prior counts)

Say's Phoebe - 1 (seen on only 8 prior counts)

LONG_TAILED DUCK - 2 (seen on 11 prior counts, interestingly the high count was 5 back in 1980)

 

Of note was a schistacea (mountain race) Fox Sparrow seen in the Bear Creek area.  Unusual for this race to remain in Colorado in the winter.


Thankfully there was open water for lingering birds like Common Loons, Western, Horned, Eared and Pied-billed Grebes, Double-crested Cormorant, Black-crowned Night Heron, etc. that helped.  A "Count Week" (see below) Greater White-fronted Goose was nice.  Harris's and Swamp Sparrows helped bring the low sparrow totals up.


One group witnessed an amazing thing:  An adult Golden Eagle carrying off with a Red-tailed Hawk in its talons!!!  WOW!!!

 

REMEMBER - There are still three days remaining to include "Count Week" birds!  Count Week (CW) birds are birds found three days prior and post Count Day that were NOT seen on the Count Day itself.  If you believe you have seen a CW species, please let me know so that I may include it in this year's final report.

 

Thanks again to all the wonderful volunteers that helped with this year's CBC!
