A parliament of crows this morning

I figured there were about 75 crows outside our back door, in three trees, engaged in pretty spirited conversation. Call-and-response-fashion one would call Cawcawcaw; and the others would not-quite-in-unison respond Caw caw caw caw. Cacaphony indeed.

It lasted nearly fifteen minutes.

I looked around for a sign of what they were going on about -- a cat or a raven or a hawk -- but saw nothing.

I have always preferred the term parliament to the more popular "murder" for a group of crows. But a friend has suggested "caucus" is better still. He may be right.
