Juvenile yellow-crowned night heron
The yellow-crowned night heron (Nyctanassa violacea), is one of two species of night herons found in the Americas, the other one being the black-crowned night heron. It is known as the bihoreau violacé in French and the pedrete corona clara in Spanish.
Although the adults are easy to tell apart, juvenile yellow-crowned night heron can look very similar to juvenile black-crowned night heron. Yellow-crowned juveniles tend to stand straighter and have heavier bills and longer legs, and their spots and streaks are finer than those of the black-crowned.
