GUILDS

Feed-guilding:

Comments on feed-guilding:
As the tufted duck occurs infrequently in North America little information is available on its activities here.

Breed-guilding:

Comments on breed-guilding:
Breeds in Iceland, the British Isles and Eurasia but not in North America *06*.

 


FOOD-HABITS

Trophic level is unknown

Comments on food habits: 
The tufted duck is a Eurasian species which occasionally occurs in North America. Little information is available on its habits here.

Comments on environmental associations:
The tufted duck is a Eurasian species which regularly occurs along atlantic and pacific coastal waters of North America and more rarely is found in inland waters *05,06*.

 


LIFE HISTORY

Origin: Exotic; rare vagrant from Eurasia *05,06*.

Physical description: Adult male - resembles ring-necked duck; principle difference is presence of their drooping crest on back of head; back is black, flanks are white; adult female - similar in appearance to female scaups but is black-brown with a smaller patch of white at the base of its bill; at the back of its head there is a slight protruberance of feathers, much more abbreviated than that of the male's. For a more detailed description of both sexes see *05,06*.

Reproduction: Breeds in Iceland, British Isles and northern Eurasia; does not breed in North America *05,06*.

Behavior: Regularly occurs along atlantic and pacific coastal waters of North America and more rarely on inland waters; is thought to migrate south with greater scaups *01,05,06*.

Population parameters: Relative trend - unknown; but numbers are increasing in sitings along north american coastal waters *05,06*. limiting factors: unknown in north america.

 


MANAGEMENT PRACTICES

Beneficial:

  • Controlling pollution in aquatic habitats
  • Developing/maintaining lakes and ponds
  • Creating/maintaining islands within permanent impoundments
  • Regulating hunting

Existing:

  • Regulating hunting

Comments on management practices:
As the tufted duck rarely occurs in Illinois there are no management practices existing for it. In general, management practices beneficial for other species of ducks would be beneficial for the tufted duck.
