There are still many questions about bird migration, including how it’s affected by climate
Millions of birds make their way through the San Francisco Bay Area on the way north to their breeding grounds every spring. Many shorebirds and waterfowl have already left, and now waves of songbirds are passing through. As well-watched as birds are, there are still a lot of things scientists don’t know about migration, including precisely where different species go each summer and winter, and what exactly triggers them to get going. Since so many birds pass through here, the Bay Area is a good place to try and sort out some of the questions, and to try to tackle another: how does climate change affect birds?
The San Francisco Bay Bird Observatory, a non-profit science and conservation organization, has been monitoring birds here for 30 years. The information collected through its bird banding program, has helped reveal some of the likely effects of climate change on birds. For example, a paper released last year suggests that climate change is making some species larger.
