Three species of swallow were present at John Heinz National Wildlife Refuge while I was there. The most common were Tree Swallows followed by Northern Rough-winged Swallows and Barn Swallows. The Barn Swallows were the most cooperative to photograph, perching on the boardwalk and not taking flight until I was about 10 feet away.

Tree Swallows were a little trickier to digiscope because they usually perched on their boxes or in trees, staying further away from me. They seemed much flightier than the Barn Swallow.

Northern Rough-winged Swallows really seem to enjoy perching on smaller vegetation on the lake, but I digiscoped this one in a tree. Rough-winged Swallows are perhaps not as strikingly colored as other swallows but they are still beautiful in a very earthy way.
