Some More Birds of the Wallace Line, Vol.2

Most of these birds are endemic to Bali and Jawa Timur (East Java) on the Sunda side of Wallace Line. Many of these bird species face risks from capture for the cage bird trade, hunting/ targeted killing, domesticated animals and habitat destruction and fragmentation due to human activity. Their range and habitats, formerly widespread and common, are now ever contracting or becoming rare and very restricted. The H5 bird flu (avian influenza) has been spreading now for about four years and will impact millions of wild animals worldwide. It will also affect a range of these wild birds.

Bali Myna (Jalak Bali). The mascot of Bali is a critically endangered white starling with black tips to the tail and wings. It has blue facial skin, and long plumes.

Yellow-throated Hanging-Parrot. Near threatened/ Sensitive Species. Tiny short-tailed Psittacidae, green overall with a bright red rump and orange bill.

Javan Kingfisher (Cekakak or Raja Udang). Sensitive Species. Brightly coloured medium-large kingfisher with a large red bill, dark head, brown throat and chest, purple body, turquoise blue wings and tail.

Javan Banded Pitta (Paok Pancawarna). Sensitive Species. A five-coloured groundbird - brown upperparts, black mask, white throat, and yellow eyebrow and barred underparts, bright blue tail and white wing stripes. This male shows its blue bib and tail and black crown.

Crescent-chested Babbler. With a black crescent across its breast, this little Javan endemic is bright rufous above and gray below.

Javan Scimitar-Babbler. A vulnerable and threatened species, of the high tropical montane rainforest. Apparently, it has fierce-eyes yellow and short typical decurved babbler bill, a black head and white throat to mid-belly that contrast with a dark maroon body. They say every birdwatcher with a camera has a photo in them. This should have stayed there.

Javan Bulbul. Forest bulbul with a long slender bill, olive back and wings, and streaked underparts.

Ruby-throated Bulbul. Vulnerable species. Black headed with a golden-yellow body. Okay. A small crest and blood-red throat. Apparently.

Sunda Teal. Bebek cokelat or Itik benjut. Small mottled brown duck with ruby-red eyes and rounded forehead with bulge.
