Is nankeen Night Heron endangered?

The nankeen night heron is a medium-sized heron. The adult male is 55 to 65 cm in length, while the female is slightly smaller, measuring 55 to 60 cm. Its weight varies from 810 g to 1014 g, and the wingspan ranges from 95 to 105 cm. Other than females being smaller in most measurements, the sexes of the nankeen night heron are alike in appearance. The nankeen night heron has a heavy black bill, which is similar in length as its head. The face is white with a cinnamon tint, and the nape and crown of breeding adults is a grey-black. During the breeding season, there are also usually two or three thin, white plumes from the crown in a downward direction to the neck. These are tipped with black when newly grown. The heron has a rich chestnut colour across the upperparts, and the colours are more intense in the breeding season. The underparts of the nankeen night heron are white, and there is a gradual blend of the chestnut colour and the white on its neck and upper breast. The back, tail, and upper wing of the bird are a rich rufous colour. The iris is of a straw yellow and can be tinged with orange during the breeding season, while the legs and feet are a creamy yellow. Their legs are relatively shorter than that of other herons, and can become bright pink during courtship and early breeding. Juvenile nankeen night herons are quite different in appearance compared to adults, with the top of their head and their nape being a black-brown colour and streaked with beige. The upper throat and chin are white, while the rest of the neck is heavily streaked with brown. The tail of juveniles is rufous-brown, the legs and feet are lime-green to olive-grey, and the bill is a dull olive-yellow colour with black on the tip. Nankeen night heron chicks are covered with dark brown down feather on their back and white on the undersides. They have cream coloured beaks with a dark grey edge, and the legs are olive. Voice Adult male nankeen night herons give a qu-arck sound when departing their roost at night, while females and juvenile nankeen night herons give a higher pitched qu-ook sound. When disturbed during roosting, the heron gives a short, deep quock. The nankeen night heron gives a hoarse, croaking quok when in flight, and a harsh croak sound while feeding in a group. The threat call of the bird is a rok sound and is used when in aggregations. Nankeen night heron chicks are described to beg with a kak-kakkak call in their first two weeks, in order to obtain the attention of their parents for feeding. They also squawk as they dispute among themselves. After leaving their nest, during the period when they are still flightless, young nankeen night herons utter a noisy high-pitched screech when alarmed.
