Purple Heron
Ardea purpurea
The purple heron is a large bird, 78–97 cm (31–38 in) in length with a standing height from 70 to 94 cm (28 to 37 in) and a 120–152 cm (47–60 in) wingspan. However, it is slender for its size, weighing only 0.5 to 1.35 kg (1.1 to 3.0 lb). It is somewhat smaller than the grey heron, from which it can be distinguished by its darker reddish-brown plumage, and, in adults, its darker grey back. Adults have the forehead and the crown of the head black, with a dark stripe down the back of the neck that terminates in a slender, dangling crest.

Yellow-crowned Night Heron
Nyctanassa violacea
Voice: The most common call of the yellow-crowned night heron is a loud, sharp and quick squawk that the bird gives shortly after taking off or uses as an alarm call or an aggression call. The young beg for food with a soft chu-chu-chu call that becomes louder as the chicks grow older and more demanding. A different range of vocalizations plays an important part in courtship and pair formation.
