Spot-billed pelican: Small for a pelican, huge for a bird. Upto ~60 inches long and could weigh upto 6 kgs (as per wikipedia).
Also known as grey pelican, their large bill and large, expandable throat pouches is something which you will rarely miss noticing. They use this to scoop up fish from the surface of the water.
They are deceptively silent for their size though, unless at their nests with some hisses, grunts or snap their bills. If you are acquainted with other waders, you would know what I mean!
A momentary relief: Recent studies show a great deal of increase of this ‘Vulnerable species to ‘Near threatened’ status by IUCN! The estimated population of this wonder species which has been revised upwards from a low of 5,500-10,000 birds (globally) in 2002 to an estimated population to exceed 5,000 birds in India alone! Thanks to the improved protection of the species in the country.
