Elusive night parrot seen in Western Australia

The elusive night parrot has been spotted in Western Australia.

Rangers in Western Australia’s remote northern salt lake country have the spotted the bird, once believed to be extinct but recently found in north-west Queensland.

Martu people’s Kanyirninpa Jukurrpa rangers and University of Queensland researchers placed five sound recorders in the Pilbara desert and an analysis of the data by the university’s Stephen Murphy and PhD student Nick Leseberg confirmed the bird’s call at two locations.

The bird was believed to be extinct but Mount Isa bird expert Rex Whitehead says the night parrot still exists in North West Queensland.

However in 2018 Bush Heritage Australia spotted and photographed a young night parrot on their Pullen Pullen reserve in western Queensland.

A study released in June found that one of the reasons why the parrot was endangered was that it has poor vision.

An international study found the bird’s critically endangered parrot’s visual system is not as well-adapted to life in the dark as would be expected for a nocturnal bird, raising concerns it might be adversely impacted by fencing in the outback.

Richard Hill’s mission to save south-west’s endangered red-tailed black cockatoo

Richard Hill shifted to Casterton 21 years ago with his family to study the region’s endangered red-tailed black cockatoo, and he’s never looked back. As a senior biodiversity officer with the Department of Environment, Land, Water and Planning (DELWP), his mission is to preserve the unique bird.

“It’s been a 21-year project looking at and understanding the cockatoo, how rare it is and what the causes of their decline are,” Mr Hill said. “My aim is to stop it from going extinct.

“This area has a really small population of about 1500 and it’s in decline. It’s quite endangered in small parts of south-west Victoria and South Australia. 

“They’re a very unique sub-species only found in this small part of south-west Victoria.”

He is part of a larger recovery team for the cockatoo. 

“There are lots of people working trying to help the cockatoo. DELWP and what I do is a small part of that,” he said. 

A major part of his work here is helping with the annual count, organised by Birdlife Australia, where willing and able volunteers head out in fleets of vehicles to track the birds and monitor their population numbers.

“The count involves up to 80 vehicles and is all done by volunteers. I’ve been doing that for 21 years,” he said.  “We try and find where the birds are and how many there are, that produces a ballpark figure – it’s not completely accurate because it’s very hard to count them in flocks. “That can happen over 20 nights but it’s the best information we have.”

He said the red-tailed black cockatoos were disappearing at high rates. 

“The bird is in decline, and now we’re trying to find out why,” he said. “The rate of decline has steepened in the last five years and we really need to work out if there’s something new we have missed. “We understand their food sources are declining and we are planting lots of trees to arrest that decline. “There might be other things affecting the birds, so we are about to launch new studies into what causes breeding success and how to help them in the wild.”

Mr Hill suspects climate change is a large contributing factor to the decline of the species.

“Climate change really is the elephant in the room for this species because it depends on the eucalyptus trees,” he said. They get seeds of a couple of species of eucalypt and their flowering appears to be linked with rainfall. Climate change may be causing them to produce less feed, we have to try and diagnose it because they are critical resources. We need to look at the ecology and find out what’s going on.”

Birds have always been Mr Hill’s passion.

“Birds are my thing, I did my masters on owls on Christmas Island and I’ve been studying birds for most of my working life,” he said.

Mr Hill and his team are looking for volunteers for the next annual count.

“The annual count takes place at the start of May and we’re always looking for people to help with that,” he said. “We’re also looking for private properties to plant more trees for the birds to feed and nest.”

Those interested are asked to contact the Birdlife coordinator on 1800 262 062.

This bird was nearly extinct. Now, its population could double thanks to an ‘epic’ breeding season

The orange-fronted parakeet is one of the rarest birds in New Zealand, but its population may have doubled after an “epic” season of mating.Staff with the nation’s Department of Conservation say they found at least 150 orange-fronted parakeets have been born this season alone. They discovered 31 new wild parakeet nests — three times the number of nests in recent years.The new births have the potential to double the current population, said Minister of Conservation Eugenie Sage in a statement. And the lovemaking could continue for several more months, as beech trees in the region continue to have one of their largest mast seasons in over 40 years.

Mast is the botanical name for nuts, seeds, buds, or fruits that are produced by trees and shrubs and eaten by wildlife.”There has been so much seed on the beech trees, the birds just keep on breeding, with some parakeet pairs onto their fifth clutch of eggs,” Sage said. “This year’s epic breeding provides a much-needed boost to the kākāriki karaka population.”Without such a large beech mast, the birds typically only have just one or two clutches of eggs.

There are currently less than 300 orange-fronted parakeets in existence

The orange-fronted parakeet was once thought to be extinct, but was rediscovered in 1993. The current population is thought to be anywhere between 100 and 300 birds, which is why this mating season is so significant.Conservation efforts in the country have helped increase the population, with organizations breeding the birds and then releasing them into the wild.The birds aren’t the only ones benefiting from the higher beech mast. The increase in seeds also means more rats, stoats and feral cats — all of which pose risks to the bird. Sage said the department’s next steps are to focus on protecting the birds from the rising number of predators.
