“We saw very few waders during our trip due the time of the year. We saw a solitary Grey-tailed Tattler (Tringa brevipes), developing breeding plumage, on the coast near our homestay. The bird is late in migration as most migration is said to happen between March–late May (HBW 2019).

This Grey-tailed Tattler is interesting in its feathers. It has retained its juvenile feathers on the rump, scapulars, middle coverts and greater coverts, which have white fringes and black sub-terminal band, fringes already worn a bit though. First summer birds do not breed in their first summer, second summer afterward they commence their breeding, so this bird is lingering around south of their breeding ground.
Amar added: So this bird is a first year bird that will not breed as yet, hence the delayed return north (lucky for us).
