It was a wader watch cum identification workshop conducted by Adesh shivkar with Mr KB singh and others.

What are the tips for wader identification ?
Divide waders by thier size
Category 1 - Stints
Category 2 - smaller plovers
Category 3 - Sandpipers and redshanks and green shanks
Category 4 - whimbrel , curlew and godwits

In category 3 size generally anything with red legs is a redshank with dark legs with big beak would be a greenshank. Common sandpiper is plain brown with always waging its tail while walking.
In category 4 - with curved beak would be curlew and similar smaller would be a whimbrel. Others would be godwit.

Brown headed gulls have a white dot on the black at the tip of its wing which is visible while in flight.
