In depth ZSL Edge names of top 25 Birds including 15 Indian globally endangered Birds
A recent study by experts at Zoological Society of London (ZSL) and Yale University has identified 100 Evolutionary Distinct and Globally Endangered (EDGE) species worldwide shows that most of the habitats are under threat from unsustainable human activities.
Of these 15 are species from India.
Following are the names of top 25 birds are on the list on endangered species because of Human actions.
1-
Giant Ibis - (Thaumatibis gigantea)
This species is Cambodia’s national bird, and owing to its rarity and exceptional size holds near-mythical status for bird-watchers, naturalists and conservationists.
The Giant Ibis now has an extremely small, declining population, concentrated in Cambodia. It also occurs in extreme southern Laos and has been sighted in Vietnam. Already extinct in Thailand, it is thought to be on the verge of extinction in other localities within its current range. It has been classified as critically endangered based on the likelihood of continued decline, predominantly due to the effects of human disturbance and hunting.

New Caledonian Owlet-nightjar - (Aegotheles savesi)
This mysterious species, which has not been seen since 1998
It is known only from two specimens, which are held in museums in Liverpool, UK and Italy. The bird is endemic to the island of New Caledonia, which is in the South Pacific Ocean to the east of Australia.
The bird has been classified as critically endangered as its population is unlikely to number more than 50 individuals.

California condor - (Gymnogyps californianus)
Exactly how many California Condors once lived remains unknown, yet by 1981 the wild population numbered at just 21 birds.
Enormous efforts have been made to save the California condor from extinction. The first successful breeding attempt from captive-reared condor’s occuredoccurred in 2003, in Arizona. There were several breeding attempts in CA and AZ in 2001 and 2002, but not until 2003 did a chick successfully fledge from a nest cave in the wild.
Distribution –
California, Northern Arizona, Southern Utah, United States and Baja California, Mexico.

Kakapo - (Strigops habroptila)
The nocturnal Kakapo or ‘owl parrot’ (so called because of its facial disc of owl-like whiskers) is a large, stocky, New Zealand endemic. It is the heaviest of all the parrots, usually gaining between 60-100% in body weight in preparation for the breeding season.
It is now extinct throughout its natural range, and survives only on three small, intensively managed islands following a series of successful translocations.
Dedicated conservation efforts have seen the population increase slowly to 125 individuals.
Distribution - Codfish Island and Anchor Islands off the South Island of New Zealand and Little Barrier Island of the North Island

About Edge –
The EDGE of Existence programme is the only global conservation initiative to focus specifically on threatened species that represent a significant amount of unique evolutionary history.
The aim of the EDGE programme is to put these species on the map and catalyse conservation action to secure their future. Each year a number of the most poorly known and neglected EDGE species are selected for conservation attention.
The ultimate goal of the EDGE programme is to ensure that local stakeholders, governments, and in-country and international conservation organisations take ownership of these forgotten species and commit to ensuring their future survival.

Refer to earlier post on Purana Qila.
A cut in Mathura Road will take you to Bharatpur. Bharatpur has a bird sanctuary. You will get tremendous knowledge there.
It is a coincidence that you wrote about birds after knowledgeful Purana Qila !!
@Kirtivasan Ganesan
