The species are: Tattlers resemble a common redshank (T. totanus) in shape and size, but not in color.

[2] Certain identification to species depends on details like the length of the nasal groove and scaling on the tarsus.

Birds in breeding plumage can also (with some experience) be identified by the underside pattern: the grey-tailed tattler has fine barring on throat, breast and flanks only, which appear light grey from a distance; the rest of the underside is pure white.

But when they flee from the observer or are otherwise startled or excited, both species alike give a variety of longer or shorter alarm calls.

[3] Tattlers are strongly migratory and winter in the tropics and subtropics on muddy and sandy coasts.
