If you are experienced identifying birds by sound as well as by sight, the North American Breeding Bird Survey (BBS) can really use your help! It involves one morning of your choosing between late May and early July and a willingness to spend the previous night, if necessary, at a location that may be a several-hour drive from your home.
At eBird Northwest, we encourage everyone to watch birds and share what they see. Thanks to Birdability founder Virginia Rose and National Audubon's Birdability Map, eBirders can take direct action to help people find accessible spaces to watch birds.
The Pacific Bushtit and Interior Bushtit populations differ visually and apparently have relatively little contact, as they are largely separated by major ecological barriers to bushtit dispersal, such as the Sierra and the Cascades. Even though Bushtits are considered relatively sedentary, both populations are expanding their range, creating the possibility of increased contact, particularly in areas where the barriers to dispersal are not as significant, such as the Klamath Basin, the lower passes in the Cascades and the Columbia Gorge.
