The mother should continue to incubate her four eggs and will hopefully be able to feed all her babies by herself when they hatch. These chicks are 3 or 4 days old. Notice all the fresh green leaves in the nest. We found six eggs in two of the nests we checked. Incubation takes 15 to 18 days.
Fresh elm leaves line the nest cup.
The males bring these leaves. In mid-May, Nest 3 was still under construction. You can see the dried grass and bark strips that make up the bulk of the nest cup.
