On April 28, 2022, I was photographing a mixed flock of swallows at Trustom Pond National Wildlife Refuge in South Kingstown, Rhode Island, when I noticed a bird that superficially resembled a Barn Swallow (Hirundo rustica) but appeared to have a cinnamon rump patch that would not be expected on a Barn Swallow. I took several photos of this bird in flight before it left. I viewed the bird only through a camera, so I was not able to study the details of its appearance until later in the day, when I reviewed the photos on my computer. This bird was associated with several Barn Swallows within a larger mixed flock of swallows, which included Tree Swallows, Northern Rough-winged Swallows, and a Bank Swallow.
