- Ground doves, known for their faithfulness to their partners until death, hatched as a result of careful diet and husbandry planning; Luzon and Mindanao bleeding heart pigeons among rare species.
Singapore, 13 February 2014 – With Valentine’s Day happening tomorrow, Jurong Bird Park is a-flutter with successful hatchings of ground dove pigeons, known for their faithfulness to their partners until death. Amongst them are Luzon and Mindanao bleeding heart pigeons, both of which can only be found in the Philippines.
After a successful two-year breeding programme, Jurong Bird Park now has ten Luzon bleeding heart pigeon progenies ready to be sent back to the Philippines this year to be released to the wild on Polillo Islands. Luzon bleeding heart pigeons are a threatened species of bird, with declining numbers in the wild due to deforestation and the illegal pet trade.
The project is Jurong Bird Park’s first off-site conservation project involving an endemic species from the Philippines in the ASEAN region. Recognising Jurong Bird Park’s expertise in conservation and breeding, two pairs of Luzon bleeding heart pigeons arrived in the park two years ago as part of an agreement signed with Avilon Zoo (Philippines) and the Department of Environment and Natural Resources (DENR) in the Philippines. These birds started breeding from October 2012 and continued through January 2014 to produce 10 progenies.
All bleeding heart pigeons and golden heart doves are part of a group of Australasian pigeons known as ground doves, known to be very faithful to their partners until death. If one dies, the other will look for another to pair up with. Upon becoming parents, both males and females will take turns to incubate the eggs. For the first few days of a chick’s life, the chick is fed crop milk produced by both genders. Once the chick is older, both parents will forage for food for the young. Ground doves are very caring, often preening each other and their chicks. They will also sun bathe together, strengthening the bond communally.
“To have 10 Luzon bleeding heart pigeon progenies available for release over a short span of two years is a remarkable achievement. This project was initiated with the aim of contributing to the recovery of this species in its natural habitat, and we look forward to developing more conservation projects for other endemic Philippine species. The success and the knowledge gained paves the way for Jurong Bird Park to engage in other similar regional conservation projects.” said Dr Cheng Wen-Haur, Chief Life Science Officer, Wildlife Reserves Singapore.
A pair of Mindanao bleeding heart pigeons arrived in the Bird Park from San Diego Zoo in September 2013, as part of an exchange programme. Although this pair was not known to be prolific breeders, they adjusted well to their new home and that a few weeks after their arrival, they laid one fertile egg, which hatched after an 18-day incubation period. Another fertile egg was laid just before Christmas last year, which also yielded a chick.
A two-pronged scientific approach involving husbandry and diet was taken towards the successful breeding of the Luzon and Mindanao bleeding heart pigeons. The Luzon bleeding heart pigeons were placed in an off-site aviary with minimal human contact, while a specialised diet with increased protein levels was provided for added nutrients during breeding season. Although the Mindanao bleeding heart pigeons were placed in a visible public enclosure, the aviary was properly landscaped, which provided the birds with a heightened sense of security necessary for breeding. Similarly, they were also given a protein-rich diet during breeding season.
In addition to the successful hatchings, Jurong Bird Park will welcome two pairs of golden heart doves from Germany for breeding and conservation purposes. Endemic to Papua New Guinea, these birds are uncommon in institutions as it is a challenge obtaining birds from New Guinea due to governmental restrictions.
Come to Jurong Bird Park this February to see the Luzon bleeding heart pigeons at the South East Asian Exhibit, and the Mindanao bleeding heart pigeons at Heliconia Walk. Two pairs of golden heart doves will be on display from April at Window on Paradise. For more information, please visit www.birdpark.com.sg
