We have a bluebird family in our backyard. The mother is at the entrance and the father is on top. The wire wrapped around is to prevent snakes from getting up the post; except the bungee cord seems to have deteriorated as it's not snug against the post any longer. We don't dare go up there and disturb the birds now. So we'll have to wait till the babies fledge.
Here's the father with an insect in his mouth for the babies. The mother always goes directly to the entrance but the father often lands on top and waits for a while. Bluebirds eat hundreds of insects; they are great in the garden. Several weeks ago the father was feeding the mother while she sat on the eggs till they hatched. We're having some glorious weather after all the rain. Thanks for reading and for all your comments.
