The diet of the Long-wattled Umbrellabird is composed of insects, lizards, and fruit, especially palm-nuts. Long-wattled Umbrellabird female by Dušan M. The first Long-wattled Umbrellabird nest was only discovered by scientists in 2003. Male umbrellabirds show off by raising their crests, inflating and swinging their long wattles, and making loud, grunting calls and low-frequency booming sounds which can be heard up to almost a mile away.Īfter mating, the female builds a loosely-built platform nest of twigs, incubates the eggs, and broods her chicks alone.

And, since this is a large and relatively conspicuous species, some local people capture them as pets, for sale to third parties, or to eat. Intensive agricultural development is a major deforestation factor, especially for oil palm and banana plantations and livestock-farming. The biggest threat to the Long-wattled Umbrellabird is habitat loss due to development, logging, road-building, and gold mining. This long wattle is covered in short, scaly feathers, and when inflated, looks somewhat like a pine cone! During mating season, the male puts these ornaments into action.įemales and immature birds are only half the size of males, and the wattle is much smaller or absent altogether. If you’re lucky, you might be able to sex your white cockatoos if they end up breeding (though this doesn’t always happen in captivity).The all-black male sports a crest of fine, hair-like feathers that hang all the way over its bill, giving it the look of having an “umbrella.” This unusual species also has an inflatable wattle dangling from the middle of its chest. However, in other species, such as the Sulphur-crested cockatoo, adults are of the same size and only display minor differences which can’t be easily observed, especially from a distance. For example, female Salmon-crested cockatoos are sometimes larger than their male counterparts. Anecdotal evidence does suggest some differences, but these are unreliable.

In other words, it’s not possible to tell males apart from females, and anecdotal tips to identify a bird as either male or female aren’t reliable. White cockatoos do not display any reliable form of sexual dimorphism. In this article, we’ll look at which species can be sexed visually, how it can be done, and how you can sex species that don’t display differences between males and females.īroadly speaking, cockatoos are categorized into three large families: white cockatoos, black cockatoos, and cockatiels.
