First egg …

IMG_4346 ldMama II worked hard  building her second nest.  She had it pretty much completed in only two days.  She brought in huge mouthfuls of nesting material.  After struggling a little with her first nest, I guess she has this nest building thing down now.

Mama spent some time in the box after breakfast this morning and I suspected she was laying an egg.  Daddy II occasionally took her a few mealworms.  Maybe appropriate that today is Mothers Day.  With a nest built and an egg in the box, we are well on our way to a second brood of bluebirds.

I’ve seen two of the fledged juveniles with the parents.  No idea if that is all that have IMG_4459 ldsurvived or the others have just not come into the yard.  Mortality is high in most species that produce a lot of babies.  That is precisely why bluebirds attempt so many nestings.  It is a stategy developed over time to keep the species going.

Daddy and one of the first brood.

Bluebird populations declined by an estimated 90% from 1920-1970 due to loss of habitat, competition for nesting cavities from introduced species like House Sparrows and starlings and use of pesticides.  Due to conservation, mainly nestboxes, Eastern Bluebird numbers have increased dramatically, but Western Bluebird populations have not.  All bluebirds still need help.  I urge folks with an interest in them to put up a nestbox or a trail of them.  Just do your homework first so you’re not erecting death traps instead of places to raise future generations of bluebirds.  To find the answer to about any bluebird question, visit

    Mama laid her second egg this morning. Daddy was in the yard with two of the juveniles from the first brood. He fed them some mealworms and then they left.
