Eastern Bluebird Juvenile Behavior

Since the second brood nestlings fledged (June 13th and 14th), I have been lucky enough to see two of the new fledglings in the trees around the yard.  The safest place for fledglings is high limbs, away from the ground and with sheltering canopy overhead.  The family often leaves the nesting area after the nestlings fledge and it's rare to see them at all in the days that follow.  
The male fledgling above happened to catch my eye while he was exploring the lichen in a tree near the patio.  His behavior, plus the rich color of his plumage and his yellow gape, helped distinguish him from his older male sibling.

A few days before fledging occurred, I captured some fun video of the first brood juveniles interacting as they came to the nestbox to feed.  The three juveniles readily cooperated in feeding with the adult male's encouragement.  The male encouraged their assistance with wing-waving, soft whistles and chattering which were also behavioral exchanges observed in the mated pair prior to the female's disappearance (last seen June 8th).  

Though they are serious about caring for their younger siblings, juveniles will be juveniles, and their interactions can be amusing.  Watch what happens when these two female juveniles land in the guard at the same time.


Below, a female juvenile feeds the nestlings, then carefully removes a fecal sac.



Next:  Watch bluebird behaviors as the whole family gathers at the nestbox to care for the nestlings!

For the Love of It...

...the sage sees heaven reflected in Nature as in a mirror, and he pursues this Art, not for the sake of gold or silver, but for the love of the knowledge which it reveals.
Sendivogius (1750)

"There is a vitality, a life force, an energy, a quickening that is translated through you into action; and because there is only one of you in all time, this expression is unique. If you block it, it will never exist through any other medium and it will be lost. The world will not have it. You must keep that channel open. It is not for you to determine how good it is, nor how valuable. Nor how it compares with other expressions. It is for you to keep it yours, clearly and directly." ----the great dancer, Martha Graham
