The Lesser Kestrel is, as the name implies, a smaller and more delicate bird than the Common Kestrel, and it is entirely sympatric in its breeding range with it; they compete to a limited extent. Thus, the possibility that there is some form of adaptive advantage to the similar coloration deserves study. Considering that the Lesser Kestrel would in fact have an advantage if some would-be predators confuse it with the larger species and consequently avoid it, it might be a case of Müllerian mimicry. (See reference re: Mullerian mimicry) (Wikipedia)
This species breeds from the Mediterranean across southern central Asia to China and Mongolia. It is a summer migrant, wintering in Africa and Pakistan and sometimes even to India and Iraq. It is rare north of its breeding range, and declining in its European range. The scientific name of this bird commemorates the German naturalist Johann Andreas Naumann. (Wikipedia)
I heard these birds before I saw them because the young one was crying for food. They live in the church tower of a tiny town I visited on my recent trip to Spain.
