Bali starling description

The Bali starling is one of the rarest birds in the world and relatively new to science being first described in 1912 by Walter Rothschild ⁽³⁾, from whom the bird gains its specific name. This medium-large starling is almost entirely white apart from black wing- and tail-tips and the striking, bare blue skin around the eye ⁽⁴⁾. The crest is long and drooping, the bill is yellow and the legs are a greyish blue ⁽⁴⁾.

Also known as

Bali myna.

Spanish

Estornino de Rothschild, Miná de Rothschild.

Size

Length: 25 cm ⁽²⁾

Weight

85 - 90 g ⁽²⁾

Bali starling biology

The breeding season runs from October to November ⁽⁴⁾ and nests are preferentially made within woodpecker holes in the trunks of trees ⁽²⁾. Males become very aggressive at this time ⁽²⁾.

Outside the breeding season, Bali starlings could previously be found in flocks of up to 40 birds, often roosting in dense coconut trees ⁽²⁾. Adults feed on ants, termites and caterpillars but also on fruits and seeds ^{(2) (3)}.

Bali starling range

The Bali starling is endemic to the island Bali in Indonesia and previously found throughout the northwest third of the island ⁽⁴⁾.

Bali starling habitat

Inhabits monsoon forest and acacia savannah ⁽²⁾.

Bali starling status

The Bali starling is classified as Critically Endangered (CR) on the IUCN Red List ⁽¹⁾, and listed on Appendix I of CITES ⁽⁶⁾. Conservationists now in fact think that the species may be extinct in the wild, but this is yet to be formerly confirmed ⁽⁷⁾.

Bali starling threats

The Bali starling has been pushed to the brink of extinction by the illegal capture of individuals to satisfy the caged-bird trade. The rarer this beautiful species became, the higher the black market price, and the wild population has consequently been decimated ⁽⁵⁾. Habitat destruction and competition for nest sites with the black-winged starling (Sturnus melanopterus), which is spreading throughout the island, are further threats to survival ⁽²⁾.

Bali starling conservation

The Bali starling has been protected under Indonesian law since 1970 and the entire recent wild population occurred within the Bali Barat National Park ⁽⁴⁾. BirdLife International established the Bali Starling Project in 1983, with the cooperation of the Indonesian government and US and British zoos, in an attempt to save this species from extinction ⁽²⁾. Armed guards protected the population within the park and captive-bred individuals were released to bolster the wild population, but numbers nevertheless continued to decline to just 36 to 40 individuals in 1994. ⁽²⁾. The programme was dogged with problems, and in 1999 an armed gang stole almost all the 39 captive individuals in the park that were awaiting release into the wild; in the same year the wild population plummeted once again, this time to just 12 individuals ⁽⁴⁾. Despite ongoing conservation efforts the Bali starling is now believed to be Extinct in the Wild ⁽⁷⁾, and the future of Bali's national bird looks increasingly bleak.
