Singapore, 21 May 2012 – Two critically endangered blue-throated macaws, three red-tailed black cockatoos and four endangered hyacinth macaws have hatched at the Jurong Bird Park’s Breeding & Research Centre (BRC). These nine breeding successes, ages ranging from three to nine months, are part of the Bird Park’s carefully managed breeding programme.
The blue-throated macaw siblings are the first ever hatchlings of this species at the Park. They hatched on 17 and 23 December last year after an incubation period of 26 days at the BRC, which is a dedicated area to ensure the welfare, breeding and promulgation of birdlife. Weighing in at 14 g and 15 g at hatching, blue-throated macaws are difficult to breed in captivity, as compatibility is an important requirement for them with regards to the environment and their breeding partner.
It took seven years of persistent research by the avicultural team at the BRC and the Avian Hospital before two fertile eggs were laid, and even more care went into ensuring that the chicks had a diet optimised for their species and their growth. When they hatched, they were fed with baby formula and were gradually introduced to a diet of various fruit such as apples, pears, papayas, and bananas, nuts such as walnuts, macadamia nuts and sunflower seeds at three months.
Although listed as Least Concern on the IUCN, the red-tailed black cockatoo is prohibited from export from Australia, making this species extremely rare in captivity. This is also the first time Jurong Bird Park has successfully bred them in captivity. The three siblings hatched in three different clutches last year, with one egg per clutch on 2 August, 9 September and 20 October.
Before fertile eggs could be laid, endoscopy was performed by the veterinarian to ensure that the breeding pair was healthy, and was ready for breeding. The BRC team also changed the nest for them by providing the birds with a log with a cavity, instead of a wooden nest box. The birds are now in the new Australian themed exhibit at Parrot Paradise, which houses seven cockatoo species endemic to Australia.
Hyacinth macaws were last bred in the Bird Park in May 2010. This breeding season, three clutches of four eggs produced four sibling chicks hatching between November 2011 and April 2012. Similarly with the red-tailed black cockatoo, endoscopy was also carried out prior to breeding. For the parents of these chicks, a veterinary check revealed that their fat intake needed to be increased to get the birds in prime breeding condition, so walnuts and macadamias were added to their diet during the breeding season.
“We are so thrilled to have a 100% success rate with the blue-throated macaw, red-tailed black cockatoo and the hyacinth macaw this breeding season. In particular, there are only about 100 – 150 blue throated macaws left in the wilds of north-central Bolivia, and we hope that they will be valuable additions to the global captive breeding population of blue-throated macaws,” noted Mr Raja Segran, General Manager, Jurong Bird Park.
