Asian Woolly-necked Stork
Ciconia episcopus
The woolly-necked stork is a medium-sized stork at 75–92 cm tall. The iris is deep crimson or wine-red. The stork is glistening black overall with a black "skull cap", a downy white neck which gives it its name. The lower belly and under-tail coverts are white, standing out from the rest of the dark coloured plumage. Feathers on the fore-neck are iridescent with a coppery-purple tinge. These feathers are elongated and can be erected during displays. The tail is deeply forked and is white, usually covered by the black long under tail coverts.

Black Stork
Ciconia nigra
The black stork is a large bird, measuring between 95 and 100 cm (37 and 39 in) in length with a 145-to-155 cm (57-to-61 in) wingspan, and weighing around 3 kg (6.6 lb). Standing as tall as 102 cm (40 in), it has long red legs, a long neck and a long, straight, pointed red beak. It bears some resemblance to Abdim's stork (C. abdimii), which can be distinguished by its much smaller build, predominantly green bill, legs and feet, and white rump and lower back. The plumage is black with a purplish green sheen, except for the white lower breast, belly, armpits, axillaries and undertail coverts.
