News of a Lesser Yellowlegs down at Old Moor reserve had me popping out for the evening to get a look at my 3rd for the UK and a 2nd for Yorkshire. On-route I picked a friend up and headed off to Old Moor and then straight down to the Wath Ings hide, where we immediately picked up on the bird in question. Noticeably smaller the the nearby Redshanks but with a slender neck, longer legs, a fine and virtually straight bill, virtually now a regular vagrant to the UK shores, breeds in N.America.
