Diurnal and nocturnal foraging by Semipalmated
Sandpipers Calidris pusilla.
Sandpiper was at Ynyslas, Ceredigion last Friday.
This agreements states that the CWS commits to protecting Semipalmated
Sandpipers at migration staging areas in the Bay of Fundy Hemispheric Shorebird Reserve, while the Surinam Forest Service commits to protecting the sandpipers on their wintering grounds in the Wia-Wia, Coppername, and Bigi Pan Hemispheric Shorebird Reserves in Suriname.
Greater and Lesser Yellowlegs and Semipalmated
, Western, Least, White-rumped, and Stilt Sandpipers, and Common Snipe were common to abundant shorebird species.
At least 11 species of migratory birds, including ruddy turnstone, red knot, sanderling, and semipalmated
sandpiper, depend on the billions of eggs that the crabs produce during the spring spawn.
When commercial harvesters dug worms from a mudflat in Canada's Bay of Fundy, the disruption destroyed other creatures that semipalmated
sandpipers eat, researchers report in the April CONSERVATION BIOLOGY.
A morphometric comparison of Western and Semipalmated
Length of stay and fat content of migrant semipalmated
sandpipers in eastern Maine.
plovers (Charadrius semipalmatus), and greater yellowlegs (Tringa melanoleuca) were rare, while snowy plovers (Charadrius alexandrinus) and lesser yellowlegs (Tringa fiavipes) were sporadic.
The lower river near Long Beach features significant migrant species, including the western sandpiper, least sandpiper, black-necked stilt, long-billed dowitcher, semipalmated
plover and black-bellied plover.
Small plovers, including Piping Plover, Snowy Plover, and Semipalmated
Plover, occurred mainly on High Mudflat/Pool and on High Algal Mudflat.
The scientists monitored how long semipalmated
and white-rumped sandpipers stayed at the Quivira National Wildlife Refuge in central Kansas and how much weight they put on during their visit.
