are small wading birds with long, thin bills.
Birds that moved freely from pond to pond to feed socially or in mixed-species flocks on fish (e.g., American White Pelican, cormorants), foliage and seeds (ducks, American Coot), or invertebrates (Northern Shoveler, Ruddy Duck, Lesser Scaup, Wilson's Phalarope
, peeps) were in larger flocks (Table 2).
(Phalaropus tricolor).--Phalaropus tricolor has become quite rare in the Calumet Region during the past decade; consequently, the 28 birds recorded at Roxanna Pond on 9 May 1978 (Kleen 1979) are noteworthy.
A Wilson's Phalarope
, a North American wader which is not normally seen in Europe, appeared at Martin Mere Wetland Centre, near Ormskirk, on Saturday.
Conwy is the only UK reserve to have three recorded visits by the North American Wilson's Phalarope
, while in April 1997 the birdwatching world descended on the reserve when a terek sandpiper spent four days there.
It also agrees with previous findings, which suggest that pond-use by breeding Wilson's phalaropes
(Phalaropus tricolor) is not driven by density, dry mass, crude protein, or gross energy content of available prey (Gammonley and Laubhan, 2002).
While the occasional Andean condor can be spotted soaring overhead, Andean geese, puna teal, and giant coots, or waders such as Wilson's phalaropes
, Andean avocets, and puna plovers are commonly found in the lakes below.
Their sheer numbers organically drawn in a single flock or gathered together on any given day on mud flats, marshlands, or open water, during spring and fall migrations, split the imagination wide-open: 10,000 snowy plovers; 17,000 Western sandpipers; 32,000 long-billed dowitchers; 65,000 black-necked stilts; 250,000 American avocets; 400,000 eared grebes; 500,000 Wilson's phalaropes
In this country, northern and red-necked phalaropes nest in Alaskan tundra, and Wilson's phalaropes
nest in inland marshes in the West.
