Field notes

  • It is capable of vertical take-offs directly from the water surface due to its high power-to-weight ratio.
  • The North American subspecies is distinguished from its Eurasian counterpart by a vertical white stripe on the shoulder.
  • They are highly social and often congregate in massive flocks numbering in the thousands during migration.
  • Their diet shifts seasonally, focusing on protein-rich invertebrates during breeding and energy-dense seeds in winter.
  • Courtship involves elaborate displays including 'pumping' the head and producing ritualized whistles.
Habitat
Shallow freshwater marshes, ponds, and coastal estuaries with abundant emergent vegetation.
Range
Breeds across northern North America and Eurasia; winters south to Central America, Africa, and Southern Asia.
