Christmas Bird Count 2017

By Sharon Cormier-Aagaard

Results of Eastside Audubon’s December 16, 2017 Christmas Bird Count

 The EAS Count Circle

On behalf of Eastside Audubon Society's (EAS) annual Christmas Bird Count (CBC), 51 volunteers were tallying outside in our CBC circle and 4 were at home watching backyard feeders on December 16, 2017.  All CBC circles throughout North America and the world are 15 miles in diameter and have a center point.  Ours is at Beaver Lake, in the city of Sammamish, and our circle has 8 sections: Marymoor Park/Ames Lake, West Snoqualmie Valley, East Snoqualmie Valley, Lake Sammamish State Park & Issaquah, West Lake Sammamish Parks, East Lake Sammamish Trail, Sammamish Plateau, and Fall City/Preston.  Several volunteers started before dawn to look for owls; some hiked forest and city park trails; many drove from spot to spot counting birds in parks and neighborhoods. The results will be tallied and submitted to National Audubon for ongoing research on bird population trends and effects of climate change.

Our 34th CBC

This was National Audubon's 118th CBC and EAS's 34th.  Our first was in 1981 (there were no counts in 1982, 1983 and 1989).  As we know, our winter weather can often be wet, windy, and cold, but oh, what a day we had! The day's temperatures ranged from 33-46F, winds were mild at 0-4 mph, skies were cloudy to partly cloudy, some areas had morning fog, some of our ponds were partially frozen, and rivers were flowing.  It was a great day to be outside bird watching!

All the birds we counted

Overall, 96 species were tallied on “count day”, plus an additional 8 “count week” birds (species reported 3 days before or 3 days after, but not seen on Dec 16), for a grand total of 104 species for this year’s CBC.  Our highest count ever was 110 total birds in 2014 (97 count day + 13 count week).  The number of individual birds seen in 2017 was 18,696, about 2,100 birds higher than the 20-year average of 16,562. The highest individual number of birds we have ever counted was 28,674 birds in 1999!

CBC Table

8 Count Week birds

Herring Gull at Lake Sammamish on 12/13, Spotted Sandpiper at Sikes Lake on 12/13, Western Gull on 12/13 at Lake Sammamish, Western Screech Owl at Marymoor on 12/14, Peregrine Falcon at Marymoor on 12/14, Violet-green Swallow at Sikes Lake on 12/14, Northern Harrier at Sikes Lake on 12/14, Tundra Swan at Snoqualmie Valley/SE 19th Way on 12/17.

Owls are always exciting… We tallied 5 different types!

2 Barn Owls (Marymoor), 1 Western Screech-Owl (count week at Marymoor), 1 Great Horned Owl (Ames Lake area), 1 Barred Owl (Phantom Lake) and 1 Northern Saw-whet Owl (Fall City/Preston area). 

First ever species in our CBC

An unexpected winter sighting of a Violet-green Swallow at Sikes Lake on 12/13 (Count Week)

Of note in this category: A Swamp Sparrow was reported on eBird at Sikes Lake and at nearby 80th a couple times before our count week and on 12/21, two days after our count week.  As the saying goes- close, but no cigar.
