There's lots of early-morning traffic coming in and out of a Blue Bird nesting box as one parent brings in food for the young while the other parent blasts out with a fecal sac for disposal.

Canon 5 D Mark III with the 500L f4 lens with 1.4 Extender II on tripod @ 1/1000, f5.6, ISO 400, +1 1/3 exposure compensation. Cropped in for composition purposes.

Cheers,

Mike
