Black crowned night herons

At The Ponds at the 'magic hour' last evening, black crowned night herons are lurking. 

According to the Cornell Lab of Ornithology: With a range that spans five continents, including much of North America, the Black-crowned Night-Heron is the most widespread heron in the world. It is most active at dusk and at night, feeding in the same areas that other heron species frequent during the day.
