Summary and Trend Analysis by Gene Hunn, CBC Compiler

The basic statistics are the ratio of the 2009 total to the average of the years 1973-2008, the “modern period” of the count

EXAMPLE: 2.56x is 2.56 times the long term average
EXAMPLE: 0.25x is just 25% of the long-term average

Trends evident:

Notably high counts include Brant (159, 3.24x 1973-2008 average), consistent with long-term upward trend; Ring-necked Duck were up (685, 3.14x 1973-2008 average), consistent with long-term upward trend; Bufflehead were up (1057, new maximum, 2.05x 1973-2008 average), consistent with long-term upward trend; Surf Scoters were at a new high, but the long-term trend is flat. By contrast, White-winged Scoters ( 2, 0.03x) and Black Scoters (12, 0.10x) were way down; As were Ruddy Ducks (2, 0.34x), continuing long-term downward trends.

Ring-necked Pheasants and California Quail have disappeared, with no pheasants reported and quail count week only (at Magnuson Park where a few hang on).

Bald Eagles continue their dramatic recovery (102, 4.91x) as do Peregrine Falcons (8, 3.26x).

On the down side are Western Grebes (1000, 0.69x, but up from last year) and American Coots (1565, 0.27x); Bonaparte’s Gulls have crashed during the 2000s, with none this year, several hundred were counted on average during the 1980s and 1990s.

Anna’s Hummingbirds continue record-setting numbers, triple last year’s record total (337, 6.37x); Barred Owls (6, 6.37x) and Western Scrub-Jays (15, 14.57x) consolidate their relatively recent invasions; American Crows continue to expand their hold on the urban environment (18,180, 26.25x).

Black-capped Chickadees (1739, 1.93x), Red-breasted Nuthatches (109, 2.04x), and Brown Creepers (62, 2.06x) were all up this year, continuing long-term trends; Yellow-rumped (168, 4.19x) and Townsends (40, 2.63x) Warblers were up; Lincoln’s Sparrows (18, 2.26x) were up this year, as were Fox (154, 1.48x), White-crowned (34, 1.38x), and Golden-crowned (153, 1.73x) Sparrows, while Dark-eyed Juncos achieved a new maximum (1098, 1.61x).

Brewer’s Blackbirds continued to be elusive (1, 0.04x), having crashed since the 1980s; Our state bird, the American Goldfinch (622, 2.72x), is on the rise, while Evening Grosbeaks have all but vanished (0) since the 1990s.
