That was our note from our reader friend Nancy who has been keeping The Squirrel Nutwork up-to-date on the Eastern Bluebird family in her yard. One day the fledglings were there and the next they weren’t.
You may have noticed in our last bluebird update that the fledglings had feathers and spots–it sure doesn’t take long to test those wings!
The bluebirds will not return to the nest once they have left, so Nancy removed the old nest material. Like many songbirds, the parents will nest again soon and raise a second brood before summer’s end.
They will collect grass again and rebuild–it seems the act of nest building is part of their whole courtship process, something squirrels don’t understand. Build a nest once and keep it repaired! That’s enough.
They would have built again right over the old nest, but that can put the eggs and nestlings too close to the hole–and the hands of hungry raccoons. If you’re keeping a box, please clean it out! Also, you might discourage House Sparrows from nesting in it.
This aggressive, non-native bird loves a good nest box. And they don’t need them, their numbers are high enough already!
Thank you to all you human readers monitoring Bluebird Boxes! It’s more than putting them up!
