Eastern Bluebird: Kennebunk, Maine, USA — A little unexpected action as this immature Eastern Bluebird throws out a wing for balance as it considers moving to the feeder. It remained perched for a few more moments before making the plunge. Sony Rx10iv at 600mm equivalent. Program mode with my custom birds and wildlife modifications. Processed in Polarr and Apple Photos. ISO 160 @ f4 @ 1/500th. Taken through thermal glass on the deck door.
