One member of a Smooth-billed Ani group often sits on a high perch and watches for danger while the rest forage.
Several Smooth-billed Ani females typically lay eggs and incubate in the same nest. Late-laying females bury the eggs of early-laying females with twigs and leaves, which can create a number of layers of eggs; only the top layer eventually hatches. As many as 36 eggs may be found in a single nest.
Juvenile Smooth-billed Anis from first broods stay with their natal group and help feed the second brood. Seems that this one is " pulling guard". Enjoy!!!
