Seeing bats swooping around is always a treat, but a large flock of birds that I noticed at dusk reminded me of the fruit bats that we saw near Periyar National Park, in South India, the winter before last.
They were a regular feature that nature tourists like ourselves watched; we went up to the roof of our (modest) hotel to see them, but the upscale posh hotel nearby advertised watching their evening flight.
We don't have fruit-eating bats in North America, only insect-eating ones. The fruit-eating bats are found in the tropics and semi-tropics (at least, that's what I remember).
