Description

This bird showed up in my neighborhood in early January, and I've been stalking it ever since. It spends a lot of time on the very top of one of the taller neighborhood trees, and I wouldn't have given it a second glance were it not being divebombed by a pair of crows one afternoon. Twice now I've seen this bird dining on a mouse or small bird such as a sparrow, and whenever it flies near any of the other neighborhood trees, every bird in the tree scatters.

The missile-like trajectory of its flight, its size (smaller than a crow, bigger than a kestrel), its diet, and its banded tail lead me to believe it might be a merlin, but if anyone else could back me up on that, it would be much appreciated.
