Two very young Anna’s Hummingbird chicks sit in the nest with eyes still closed, necks outstretched, and beaks open. These baby hummingbirds hatched from the eggs pictured in Hummingbird Eggs in Nest.
Notice how short the chick’s beaks are at this stage of their growth. As a size comparison, leaves from the Texas Ebony tree are about 3/8th to 5/8th of an inch (0.9 to 1.5 cm) long in the area near the nest. See the next photo for a comparison between the young chicks’ beak size and their mother’s full grown beak.
The chicks’ beaks will be longer and showing less yellow by the time they leave the nest. See this photo of the same two hummingbird chicks a few days before they fledged.
