The Wahkiakum Christmas Bird Count circle straddles the Columbia River, including Cathlamet, Puget Island, Elochoman Valley, and parts of the Skamokawa Valleys in Wahkiakum County, Washington; and Westport, Brownsmead, and Knappa in Clatsop County, Oregon. The Julia Butler Hansen National Wildlife Refuge and most of the Lewis and Clark Refuge are also within the circle.
For the 23rd annual Wahkiakum CBC on December 29, 2020, 19 volunteers counted 60,501 individual birds representing 109 species (there were two additional count week species). This is close to average - pretty good, considering that we had half a dozen fewer participants than usual.
The most abundant species this year was Cackling Goose at 19,750, followed by Greater Scaup (14,531), European Starling (4235), and American Coot (3297). Unusual species include the first White-tailed Kite on the count since 2012.
When I started the Wahkiakum count in 1998 White-tailed Kites had been expanding their range northward and were regular here through the early and mid 2000's, with the population peaking at 11 for the count circle in 2006. Their population in Washington plummeted after the heavy snow of 2008-9, and our numbers for the Wahkiakum count dropped to 4, then 2, then 1 for 2011 and 2012 before they were gone. The present individual can still be found along North Welcome Slough Road, Puget Island, where many birders have gone to view it. Puget Island also had three Turkey Vultures on this year's count - this is the fourth year in a row Turkey Vultures have wintered on Puget Island, after no previous Wahkiakum CBC records.
New high counts were set this year for eight species (for each I have this year's numbers, followed by the previous high count in parentheses):
- Mourning Dove 66 (64)
- Northern Flicker 67 (64)
- Black Phoebe 12 (11)
- Horned Lark 58 (44)
- White-crowned Sparrow 139 (97)
- White-throated Sparrow 9 (6)
- Western Meadowlark 65 (41)
- Brown-headed Cowbird 22 (13)
Notable among these are the large number of "Streaked" Horned Larks. Since this subspecies was listed as threatened under the Endangered Species Act in October 2013, the Army Corps of Engineers has been managing their dredge spoil islands to maintain habitat for the larks, and it appears to be helping them.
Also notable is the increasing number of Black Phoebes, which have been expanding their range northward and have been breeding successfully in Wahkiakum and Clatsop counties in recent years.
