Breeding season is a very busy time for Eastern bluebirds.
The adult pair, three juveniles from their first brood, and five hatchlings (hatched on May 27 and 28th) make up the bluebird family of ten that are living in and around the nestbox and mealworm feeder in my yard. Above you see the hatchlings on May 28th. Consider that the nest cup is approximately 2.5 inches across and you will get a better sense of the size of these tiny, newly hatched babies.
By this time, the fledged juveniles are feeding themselves. They have received firm warnings from both parents, beginning well before the eggs hatched, so that they no longer expect to be fed when a parent arrives with food. In fact, the juveniles are very curious about what's happening in the nest box and are watching as their parents bring food to the young in the nest.
And the foods offered to the nestlings are very particular and tender. In the first few days, the parents bring the tiniest spiders, worms and insects to the young. One wonders how they ever see and capture anything that small, especially when the feeding intervals can be as frequent as four times a minute with both parents feeding.
Above the female pauses before entering the nestbox entrance, and below she takes a break for a cool bath.
One of the juveniles considers taking a bath, below, but was too timid on this occasion to jump in. Perhaps she was a bit camera shy. I suspect she drinks and bathes frequently at other times during the day since we've been having 90 F degree temperatures, much warmer than is typical for this time of year in Tennessee.
