Recently, several listeners have written to us wondering about the large flocks of crows they see darkening the skies over the Bay Area at sunset each night. The crows are like clockwork, swarming to the same locations night after night, often hundreds of them at a time. What's going on? We get answers and along the way explore why we're seeing more crows in the Bay Area in recent years and if they are having a negative impact on other bird species.
