We had the nets set pretty quickly and the majority of the team settled down in the hide for a long vigil as dawn broke and the tide rose. Once again luck was on our side and we made a good catch comprising 126 Redshank, 8 Dunlin & a single Curlew.
It was a good opportunity to look at ageing the Redshank something generally done by the state of the tertials. Juveniles (age code 3 born this year) generally have very worn tertials with the weaker white 'teeth' worn away so the edge resembles a bread knife blade -see below.
Very occasionally these can be so badly worn that very little white is visible at all. This can cause confusion making the bird look similar to an adult although other plumage / bare part characteristics can be used to determining the correct age. Juvenile Redshanks generally have paler legs than adults and are a yellowish orange.
