Birds cool off by opening their beaks or bills to breathe cooler air into their system. So on a hot day or evening if you see a bird panting, they are just trying to keep cool. They also will often try to sit or perch in a shady spot or wade in a stream, pond or lake. I took these photos last night at dusk here in The Villages, Florida.
