Perched Northern Rough-winged Swallow
Northern Rough-winged Swallows have a wide range in North America but because of their drab colors they are often overlooked by bird photographers, they are the "plain brown bird" of the swallow family.
Plain Brown Bird?? Pfflllt…
I've heard people call Willets "Plain Brown Birds". I reckon they may have never seen one looking like this Willet.
