The Audubon Society Field Guide to North American Birds: Western Region

397 - least auklet - noted that in June certain birds came back daily from their diving and feeding and sat on the snow in a certain pattern. [...] showed that the "snow sitters" sat on their future nest site and took possession as soon as the snow melted. Perhaps oriented by a few large boulders, they were apparently able to locate the nest site they had used the previous season.
486 - rough-winged swallow - outer primary has tiny hooklets on the outer vane [...] near the end of the shaft, visible only under a magnifying glass. Their function is unknown.
531 - sharp-tailed grouse - In one case, when a homestead was built over the lek, the grouse displayed on the farmhouse roof the following spring.
580 - skylark - [a small introduced population lives on the Saanich Peninsula; some colonists on leeward slopes of the San Juans.]
597 - Allen's hummingbird - Experiments I have conducted at my feeder show that when the air is cool the bird conserves body heat by withdrawing its feet into the patch of down that covers its belly. In warmer weather, the toes are unfolded from the downy "muff". When the air is hot the hovering bird cools itself by dangling feet and toes.
599 - wrentit - hesitate to cross open spaces of even 30-40 feet, and it is believed that the wide Columbia River effectively stops it from entering Washington, even though that side of the river offers suitable habitat.
631 - scrub jay - also eat acorns and have been described as "uphill planters," counterbalancing the tendency of acorns to bounce downhill.
650 - yellow warbler - If the female Yellow Warbler discovers a cowbird parasitizing her nest, she quickly covers the alien egg with a new foundation and lays another clutch. One nest was found to be five layers deep.
704 - northern three-toed woodpecker - When the nestlings are well grown, their presence can be detected by tapping the tree: a loud buzzing, squealing chorus answers at once.
728 - gray jay - It stores scraps of frozen meat, suet, or hide, gluing them into balls with its saliva and hiding them among the needles.
733 - Mexican chickadee - Like other chickadees, it has an ingenious arrangement of leg tendons which enables it to pull close to a branch while upside down. Vireos, warblers, and kinglets must hover above branches, and cannot reach their undersides [...]
