Not really a chorus; a very clear messaging system from tree to tree to tree.
They’re usually high up at some distance in our forest, but for the first time I heard one piercingly close call. Just one loud guttural repeated note; not the famous who cooks for you business.
“Too dark to see it,” said Mr UD as I grabbed my binoculars.
“I’ll try anyway,” said I, scanning nearby branches.
But it flew off, signaling with cooks for you and a whole bunch of other sounds that it was changing location.
And then — at least two other owls elsewhere in the woods answered this first one, with yet other songs.
And the whole group flew off.
