Our fourth bird species in the Birdorable Bonanza is the Twenty-eight Parrot, a sub-species of the Australian Ringneck.

Twenty Eight Parrot by Stephen Barnett

The Australian Ringneck is a beautiful species of parrot native to Australia. They live in southwestern forests of coastal and subcoastal Western Australia. The Twenty-eight Parrot is named for its call! It sounds like it is shouting out 'twentee-eight' when it calls. The bird eats mostly on the ground and its diet consists of seeds, fruits, insects and flowers.

Tomorrow's bird is an endangered species that makes an epic migration from the southern tip of South America to the Arctic. Can you guess what it will be?

For 19 days we're adding a new Birdorable bird every day as part of our Birdorable Bonanza 2011. We're counting up to revealing our 350th species! Today's bird is the Cinereous Vulture.

Cinereous Vultures are huge birds of prey that range through parts of Europe and Asia. They are also known as Black Vultures (no relation to the American Black Vulture) or Monk Vultures. In their south European range, they are in trouble. Poisoning is a major problem facing these and other vulture species, but habitat loss and food scarcity are also detrimental to the survival of the species. Researchers from the Denver Zoo conducted a study which revealed that Cinereous Vultures use a huge range of territory. Birds tagged with wing markers similar to those used on California Condors were found 1200 miles from their point of origin. While the birds were tagged by scientists, follow-up data provided by keen-eyed birdwatchers helped to complete the study, which is on-going.

Tomorrow's bird is an Australian parrot that is named after a number.

For 19 days we're adding a new Birdorable bird every day as part of our Birdorable Bonanza 2011. We're counting up to revealing our 350th species! Today's bird is the Shoebill.

The Shoebill is a remarkable-looking bird with an amazingly huge shoe-shaped bill. These large birds measure up to 59 inches (150 cm) tall and their bills average 12 inches (30 cm) in length, giving it the largest bill of all bird species! The edges of this large bill are very sharp, allowing the Shoebill to cut up its food before swallowing it. They feed mainly on aquatic animals like baby crocodiles and fish. Shoebills live in parts of east Africa, with most individuals living in the Sudan, and are considered vulnerable, mainly due to habitat loss.

Tomorrow's bird is the largest 'true bird of prey' in the world. It breeds in high mountains and large forests across southern Europe and Asia. Can you guess what it will be?

Today we're starting our third Birdorable Bonanza! For the next 19 days we'll be adding a new Birdorable bird species every day, counting up to our 350th species! See our Meet the Birds page to see all Birdorable birds. The first bird to kick off Birdorable Bonanza 2011 is the Eastern Screech Owl!

The Eastern Screech Owl is a small species of nocturnal owl that lives across parts of Eastern North America. All birds have prominent ear tufts (laid back flat in the photo above) and a mottled and cryptic plumage, which comes in two distinct color morphs: red-phase (or rufous-phase) and gray-phase. Eastern Screech Owls are nocturnal and will roost in tree trunks or cavities during the day. Despite their name, their call is a descending, soft whinny.

Every day of the Bonanza we'll give you a hint for the next day's bird and you can guess what it will be. We'll start easy: tomorrow's bird lives in Africa and has a bill the shape of a shoe. Can you guess what it will be?

We don't have to add too many birds to reach another milestone on Birdorable: 350 birds! That's a lot of species. We think this milestone deserves some celebration, in the form of a Bonanza! Get ready for the 3rd Birdorable Bonanza! Later this month we'll start unveiling a new bird every day for 19 days in a row -- until our 350th bird species is added to the site. Here's a teaser below. Can you guess what birds we'll be adding?
