Madagascar Nightjar at day

During our trip in Madagascar, several times we heard a distinct animal call that sounds like a pingpong ball dropping, usually around the time the sun was setting. Little did we realize this was the call of the Nightjar, a nocturnal bird.

They are reasonably common in Madagascar, but it is less common to find them sleeping on the forest floor during the day, even less common to find two keeping each other warm. Check out their enormous heads and tiny beaks.
