This roost started forming 3 days ago. Since yesterday, MANY MORE have shown up. I'm one-by-one counting 250 in one of the trees in my backyard, but my neighbor easily has over 1000 of them in hers. I don't know how long they are staying yet. There's lots of nectar sources nearby. There's a small grove of trees they are roosting in, but not one particular kind. They seem to be fairly shielded from the wind. The wind has been blowing, but not hard. Been chilly in the mornings (high 50s, low 60s F) and hot in the afternoons (above 85°) with high humidity.
I've been watching them all day. In the morning I can walk right up to them and they won't fly away. I'm guessing they're cold. In the afternoon they are very active flying everywhere, and at 6:30 they start filling the trees, huddling together in large groups.
