The Australian white ibis (Threskiornis molucca) is a wading bird of the ibis family, Threskiornithidae. It is widespread across much of Australia. It has a predominantly white plumage with a bare, black head, long downcurved bill, and black legs.

2025年2月18日 · Egg size is a useful metric for maternal investment, offspring quality, and contaminant studies. Yet these values and the egg shape coefficients required to estimate egg size are not available for many species, including White-faced-Ibis (Plegadis chihi).

One of the most numerous wading birds in Florida, and common elsewhere in the southeast. Highly sociable at all seasons, roosting and feeding in flocks, nesting in large colonies. When groups wade through shallows, probing with their long bills, other wading birds such as egrets may follow them to catch prey stirred up by the ibises.

monogamous White ibises breed once a year dur­ing the spring months, from March to April. Dur­ing the egg pro­duc­tion stage, which oc­curs 4 to 5 days after mat­ing, fe­male ibises lay one egg every other day, with an av­er­age clutch size rang­ing from 2 to 4 eggs. In one rare in­stance, a clutch size as large as 7 eggs was recorded.

The African sacred ibis (Threskiornis aethiopicus) is a species of ibis, a wading bird of the family Threskiornithidae. It is native to much of Africa, as well as small parts of Iraq, Iran and Kuwait. [1]

Most species lay around three eggs per season, and their incubation period is about three or four weeks. Depending on the species, the chicks begin learning how to fly when they are a month or two old.

2013年7月28日 · It’s curved bill is sensitive to touch and used to probe for food in mud and under water. The majority of the Ibis’ diet includes fish, snails, frogs and insects from the water. They occasionally prey on the eggs and young of other types of birds. The Sacred Ibis is sometimes a scavenger, found going through trash or hanging around restaurants.

2021年10月19日 · Our results provide the egg shape coefficients necessary to accurately estimate egg volume and fresh whole egg mass at laying of White-faced Ibis, which will support future studies that require those data, such as research into …

Sacred ibis breed in colonies and males will collect nesting materials while the female builds the nest. 2 – 3 eggs are laid and the male and female take turns incubating the eggs and will help raise the chicks together. Sacred ibis are a social species and they roost and forage in groups. Range Native to Sub-Saharan Africa and parts of Iraq.

The exposed skin is pinkish initially, apart from the tip of the bill which is dark gray, but turns gray within a few days of hatching. The bill is short and straight at birth and has an egg tooth that falls off between days five and nine, and develops three black rings from around day six, before turning gray by around six weeks of age.
