Hi, this is Rudy Mancke from USC for NatureNotes.
Bob took some photographs that he shared with me and was interested in a dragonfly that he had seen on Bull Island, SC. And it turned out it was the four-spotted pennant.
Now a pennant, you know, is one of those sort of triangular shaped flags that you see on boats and other things. Four spots on the wings, and it always perches right at the tip of a branch as if it were a pennant. It's the only dragonfly that we've got that has all-white stigmas, those little thickened areas that support the edges of the wings.
He also had a photograph of two black-bellied whistling ducks with a group of roseate spoonbills. Wow! Those are two amazing birds in South Carolina
