Australian White Ibises. The lead bird, in this single file, looks to be a juvenile. The other two have long neck feathers. Cannot find anything about these neck feathers on these birds or why they have them plus they aren't always visible. Their lacy tail feather covering is really noticeable in this shot. Hadn't seen how delicate this tail plumage was, nor the neck feathers, on these birds before.
As mentioned in previous threads, this is a large bird, around 65–75 cm (25–30 in) long. Its beak measures over 16.7 cm (6.6 in) in the male, and under in the female. Male birds are also slightly heavier weighing around 1.7–2.5 kg (3.7-5.5 lb) while the daintier female tends to weigh around 1.4–1.9 kg (3.1–4.2 lb). Both are larger than the American White Ibis generally attains 1 kg (2.2 lb) in weight.
The Australian White ibis is a wading bird but is happy to prowl on dry land for food. It is also a roosting bird which can look quite a sight due to their size.
