There’s a New Bird in Town
The Black Tern is a rare bird in Yelapa. The tern looks like a very small gray, black and whitish gull (9 ¾ inches tip of beak to tip of tail) has a small black beak and flies in small and medium-sized flocks over Yelapa Bay.  They feed on insects and the small aquatic animals washed down the El Tuito River into the bay.  They are fairly near the shore so you can see them without binoculars. They winter near Panama and pass through our area on the way down and up the Pacific Coast to nest and raise their young as far north as the warmer southern and south eastern states in the US.
Terns seem to scoop food off the surface or very near the surface-hovering and then just breaking the surface of the water with their beak or head only. The terns have a high-pitched and continuous call.
