Where is it found? Preferring vertical cliffs, in canyons or on the coast, black swift nests on damp rocks behind waterfalls and near streams.

When was the first black swift nest discovered?

It wasn’t until 1901, when A. G. Vrooman, an egg collector, found the first nest of a Black Swift on a sea cliff near Santa Cruz, California. But his discovery was cast aside as a storm-petrel nest, until 1914 when Vrooman showed William Dawson, an ornithologist, the nest and he deemed Vrooman’s sighting credible.

Where do black swifts come from?

The African Swift or African Black Swift, Apus barbatus, is a small bird in the swift family. It breeds in Africa discontinuously from Liberia, Cameroon, Democratic Republic of the Congo (formerly Zaire), Uganda and Kenya south to South Africa, and on Madagascar.

Why is it difficult to study the black swift?

Black swift has been difficult to study due to its remote nests and long-distance foraging. The first black swift nest was not documented until 1901 in California. Black swift lays a single egg and builds its cup-shaped nests out of mud and plants, often adding material to reuse over the years.

Why are so many British Swifts being lost?

More than half of British Swifts have been lost since 1995, but the reasons underpinning this decline are unclear. BTO scientists are involved in research aiming to address these knowledge gaps, including tracking work using the latest technology.

Why are Swifts so hard to study?

Because they never land on the ground, and are so fast and so totally aerial, Swifts are very hard to study. There’s still an awful lot that we don’t know about them, making them a real Mystery Bird.

How did the swifts get into the family’s house?

The family in the Los Angeles suburb came home from dinner to find their house had been invaded by an enormous flock of chimney swifts. And the birds, who pass by the region on their annual migration, swarmed around the house and made their way in down the chimney.

Are the swift parrots in danger of extinction?

“Irrespective of where swift parrots nest on mainland Tasmania, the threat of being eaten by sugar gliders is real and is driving the species on an extinction spiral.”. Scientists estimate the bird could be extinct within 16 years.

How are Swifts and swallows related?

These avian aerialists—swifts and swallows—may look similar and exploit the same niche, but they’re not related at all. They only resemble each other because of convergent evolution, which means they’ve developed some of the same physical traits to adapt to their shared environment. So how does the enterprising birder tell them apart?

Why are swift parrots endangered in Australia?

During dry years, when the eucalypts’ flowering is poor, Swift Parrots are forced to travel far and wide to find sufficient food, and may congregate into large flocks at sites where it is available. The Critically Endangered Swift Parrot is a migratory bird too – one of only a handful of migratory parrots in Australia.

Is there a swift parrot monitoring program in Australia?

A Swift Parrot monitoring program is undertaken annually by the Australian National University between October and January. An observation of foraging Swift Parrots or a potential nesting site is valuable information. Please report all observations of this species to the Threatened Species Section.

How will logging affect the swift parrot?

Logging has already had severe impacts on habitat availability in recent decades and there is evidence that up to 23% of swift parrot breeding habitat has been logged just in the Southern Forests region of Tasmania over the last 20 years.

Why is the swift parrot population decreasing?

The major cause of the decline of swift parrots is the loss of Blue Gums in their Tasmanian breeding areas due to land clearance, and the loss in area and quality of Box Ironbark Forests and woodlands on the mainland. Most of these winter flowering eucalypt

What does the reclassification of swift parrots mean for the species?

“The reclassification is a major milestone for swift parrots and highlights the importance of finding a solution to the extreme effects of sugar glider predation, and of protecting their habitat,” Dr Stojanovic said. “It confirms that the severe predation on swift parrots by sugar gliders is critical to whether their population survives.

What kind of bird is a swift parrot?

The Swift Parrot (White 1790) is a small fast-flying, nectarivorous parrot which occurs in eucalypt forests in south eastern Australia. Bright green in colour, the Swift Parrot has patches of red on the throat, chin, face and forehead which are bordered by yellow.
