Identification and comparison of
Lesser and Greater Sand Plovers
Lesser Sand Plover Charadrius mongolus
Common summer
visitor. Small (19-21 cm), grey-brown above and white below, with grey-brown
breast patches. Large eyes. Short stout black bill and dark grey legs, sometimes
tinged greenish. Dark mask through eyes. In breeding plumage has black mask on
face and chestnut on sides of neck and breast. Soft trilling calls. Mudflats and
sandy beaches.
Greater Sand
Plover Charadrius leschenaultii
Common summer
visitor. Medium-sized (22-25 cm), grey-brown above and white below, with
grey-brown breast patches. Large eyes. Very similar to Lesser Sand Plover but
larger and paler, with larger head, longer thicker bill and longer legs (often
paler). Flat forehead. In breeding plumage has black mask on face and chestnut
on sides of neck and upper breast. Soft trilling calls. Mudflats and sandy
beaches.
General: Greater
is larger, more attenuated and less plump than Lesser, with flat forehead giving
tapered look from head to tip of bill. Lesser has smaller rounded head with
steeper forehead. Greater generally has horizontal posture whereas Lesser often
stands upright.
Plumage
(non-breeding): Greater
has paler upperparts than Lesser, with pale fringes to feathers. This gives a
more contrasting overall appearance than the smoothly dark brown upperparts of
Lesser, with the folded wings of Greater often appearing paler than rest of
upperparts. Greater also has cleaner white flanks than Lesser. Lesser often has
darker smudges around and below eyes than Greater, contrasting more with rest of
face.
Bill: Greater
has longer, more tapering and pointed bill than Lesser, which is short and
blunt. As a rule of thumb, if the length of the bill is the same as the distance
between the base of the bill and the rear of the eye, it belongs to Lesser. If
the length of the bill is greater than the distance between the base of the bill
and the rear of the eye, it belongs to Greater.
Legs: Greater
has longer and paler legs than Lesser, although the colour varies for both
species. Greater has greyish-green to yellowish-pink legs and Lesser has
blackish to olive-green legs.
Flight: Greater
has conspicuous white wingbars that are more prominent on the outer wings and
extensive white on tip and sides of tail. Lesser has less conspicuous white
wingbars that are more prominent on the inner wings and less extensive white on
tip and sides of tail. Longer legs of Greater extend beyond tail, whereas those
of Lesser do not. These features are of limited use in the field.
Call: Both
species have soft repeated trilling calls. Lesser also has a shorter and firmer
trill but this also is of limited use in the field.
