Thanks for looking. Your C/C and suggestions are appreciated.
An Eastern Bluebird removes a fecal sac from the nestbox to keep it dry and clean reducing exposure to pathogens and parasites while reducing cues predators use to find nests.

Interesting behaviour shot, and I appreciate your info.
The bird is a bit soft, probably motion blur because of the shutter speed.
Were you using flash as your main light, or as fill?
It looks like you missed the focus on this one, going to the perch on the left. Very nice behavior captured, if you have access to them, certainly try this a few more times, excellent subject!
