I haven't seen any Northern Hawk Owls this far south, so I guess it's not too cold up there! This time of year is great for bird sightings in the Caribbean. I love watching the sea eagles and hawks and such when they find a good thermal near my house. I have seen a few birds here that are endemic to my island group, a woodpecker and an ani. We have several kinds of hummingbirds here as well. I really need to get myself a book of Caribbean birds...
