Curlew Sandpiper
Calidris ferruginea
The curlew sandpiper is a small wader 18–23 cm in length and weighing 44–117 g. It has a wingspan of 38–46 cm, a bill length of 32–44 mm, and a tarsus (the bone between the "knee" and the "ankle") length of 26–34 mm. It has a black bill, dark brown irises, and dark grey to black feet. All plumages have a large white patch on the rump, occasionally barred with red in some adults, and in flight show a distinctive white stripe going across the wing. Like most waders, the curlew sandpiper has seasonal plumages and moults yearly, shedding its old feathers and growing new ones. Voice: Only the male sings. Each song lasts for 10–15 seconds and consists of several parts, starting with several introductory notes, followed by multiple trilled doublets, a four-part phrase, and several drawn-out whine calls. Both genders vocalise calls. The alarm call is a whik, whik, whik repeated or wik-ki-ki-ki...

Little Stint
Calidris minuta
Its small size, fine dark bill, dark legs and quicker movements distinguish this species from all waders except the other dark-legged stints. It can be distinguished from these in all plumages by its combination of a fine bill tip, unwebbed toes and long primary projection. The call is a sharp "stit". The breeding adult has an orange wash to the breast, a white throat and a strong white V on its back. In winter plumage identification is difficult. Juveniles have pale crown stripes and a pinkish breast.
