Starting Their Second Brood
I think the Bluebirds are getting more comfortable with our garden now. They no longer leave us during winter. We provide roosting boxes, food and water in heated birdbaths when nothing much is around in winter and we help with guarding their nesting box during their breeding season. Since they have become our resident birds, they have started their nesting early. Last year they had two broods and this year they have already started a second brood while still feeding their chicks from the first brood.
They started the first brood in April. Once the female lays eggs, we start to monitor the nest box weekly to make sure they are fine. Four out of five eggs hatched with the 1st brood.
We stopped checking their nest box when the chicks have full feathers. If they fledge too early, out of concern for their own safety, they could become other birds food. So we don’t want to stress them with visits.
The second nest is right by our vegetable garden and the green pole is only a couple of feet from the front of the nest box. Hopefully there will be another three or more chicks from the second brood.
