Wrentit molt

So, usually wrentits will replace all of their feathers during their first molt in the late summer of their hatch year, but the one we caught today seemed to have retained a few, something we rarely see.

Right wing, with one retained secondary (light brown compared to gray)

Left wing, with three retained secondaries
