Not sure what the baby birds are. We have a row of 14 Leyland Cypress that we planted in October of 2004 when we purchased the property.
This year they have been full of nest. A few weeks ago Jimmy took Mason to see the baby birds. So a week ago when they were at the house Mason wanted to go see the baby birds. Papa (Jimmy) had to explain the baby birds were already gone.
But then Saturday afternoon we found yet another nest with more babies. They will probably be gone before Mason comes back this coming weekend.
