One flew over the Cooke-coos nest

Perhaps someone out there can explain some bird behaviour for us. We've begun noticing every evening flocks of crows flying in one direction, about 30 minutes before the sun goes down. 15 minutes before the sun goes down jackdaws come flying by. Loads of them. I read once that these sorts of birds all roost in one tree, or clump of trees. Now that it is winter, I suppose this is what they are doing. It is nice to see them, right on schedule, telling us that the working day is almost over.

You may have read the post about the electricity going out. Well, what we neglected to explain is that it goes out rather regularly. At least once a week. But never when the neighbours upstairs are blasting their loud heavy metal music.
