It didn’t take Mama II long to give us a pretty powder blue egg. Even though the north wind is blowing and it’s cool, she produced the first egg of her first clutch just three days after completing her nest. Bluebirds can lay an egg every day if the weather is good and the stars are aligned, but it’s not unusual for them to skip a day or two if the weather is cool.

Bluebird eggs are about the size of a nickel. A clutch consists of 4-7 eggs, though I’ve never had more than five in my nest box. Once the female’s clutch is complete she will begin incubation. This allows the eggs to hatch at roughly the same time. Bluebirds tend to lay larger clutches earlier in the season and northern bluebirds lay larger clutches

than southern birds. But the southern birds lay more clutches due to the longer season, so I guess nature has its peculiar way to see that these beautiful little birds persist.
Once the egg laying process begins, this young pair has a sizeable investment in this brood. I should be able to sit out on the patio and watch them and take photos without them spooking. Just in the past few days has Daddy II evidenced he is making the connection that I am the source of the mealworm, not some mysterious iron object. My old male could be a quarter-mile away, see me in the back yard and he would immediately come to see if he could mooch a meal. Hopefully, this pair will bond with me as solidly as our original Mama and Daddy that we enjoyed for five years.
