May: Migrants and Bluebirds

International Migratory Bird Day is May 11, the first of two migratory-bird days this year, in order to include both the northern and southern hemispheres in the event. The second is Oct. 5. One of this year's featured species is the American Kestel, a beautiful small raptor that is native to Southern California, including the Channel Islands. Though they are here all year, the population swells in winter as Kestrels migrate in from colder areas. Their primary diet is large insects, though they will take the occasional lizard or rodent, which is congruent with the theme of Migratory Bird Day, “Protect insects; protect birds.”
