Wow, I have never seen a crow take a bird that large. But in California I have seen a dozen ravens stand over a chimney as Vauxs Swifts came in to roost, and each raven would take a turn flying over the entrance and grab one of the swifts as they began to enter the chimney. This was a large colony of nearly 15,000 and about 10 swifts would enter each second. The swifts were so habitual and had so little suitable roosts available that they were never deterred, even though the clever Ravens made easy pickings from them each night.
