Dear Arvind,
Thank for this list of publications. Many
Especially N 3,4, 5 and 8, witch confirmed the présence of bird pollinisation in Asia, but non in ORCHIDACEA family
Best regards,

Dear Aamal,
you not good see my question - I am interested in Asian pollinators-birds, and not African or American
there are three main families of pollinating birds : Trochilideae (humming-birds) in Americas, Nectarinideae (sunbirds) in tropical Africa and Asia, and Honey-eaters (Meliphagideae) in Australia. Sunbirds are known to pollinate orchids e.g. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2803388/
Sunbirds are considerably heavier than most hummingbirds, so they need more robust flowers and larger nectar rewards, as well as convenient perches. They mostly visit trees and shrubs in Asia, and some robust-flowered herbs like Zingiberaceae. Honeyeaters, which have spread west as far as Bali and Sulawesi, are mostly even bigger and are usually seen visiting trees.
Dear collegues,
Thank-you so much. It's great pleasure for your valuable comments.
Yours sincerely,
Marpha
