We finally figured out one major reason why we were getting Baltimore Orioles at the birdbath at DeKorte Park's butterfly garden. The birds had one of their amazing basket-like nests right next door, on a tree over the roadway maybe 15 yards away.
Which answers NJMC Staffer Jack Snipe's longtime question: Why is there a birdbath in the butterfly garden? (Because of the B.O. — Baltimore Oriole.)
