8/4: not a screech at all

We swam in the lake at sunset, and then some of our neighbors came down to the dock and we stayed to chat with them.  By the time we got up the hill to our house it was dark.  We heard a bird-call we've never noticed before:  it sounded like a horse whinnying.  Turns out, it's a screech-owl.  They're mentioned all the time in ancient literature, but until tonight I didn't know what one actually sounded like.
