Babies at day five

I checked the nest this afternoon to determine the status of the unhatched eggs. To my surprise, one was missing. I removed the other and cracked it to examine the contents. There was no embryo, just yolk. I wonder if the other one wasn’t the same way and the parents removed it. Sorry, no pic of the egg autopsy.

The babies grow noticeably every day. The parents started feeding them  mealworms today. Daddy divided up about 20 among the family this morning and I’ll put some more out in a little while and sit out on the patio for awhile and watch the feeding. Last year Daddy would gather up several at one time when he took them to the young.

This pic is not good quality, but shows Daddy removing a fecal sac. Normally when the adults exit the nest box, they stick their head out and make sure the coast is clear before they fly.  This gives me time to adjust shutter speed and focus, but, I guess if you have a mouth full of feces you are in a hurry. Twice today I missed Daddy removing a fecal sac.  Cavity nesting birds like chickadees, titmice and bluebirds have a unique tactic to prevent nest fouling. The baby’s feces is enclosed in a thick, white, gelatinous membrane which is removed by the parents. Feeding stimulates evacuation.

  1. Hi Lindell, Your pictures are wonderful! I am so impressed with the parenting of the Bluebirds. Have a super nice day and thanks for sharing the information and pictures of the babies!

    Bluebirds really are devoted parents. Their life revolves around taking care of their babies. They are also devoted to each other. Other than when they are off hunting for food for babies, I never see one bird without the other being nearby.
