The Philippine duck is a dabbling duck and a member of the genus Anas. It has no subspecies and so it is monotypic. [3] It belongs to the Pacific clade of Anas along with the koloa, the Laysan duck, the Pacific black duck, and the extinct Mariana mallard. [4] The scientific name comes from the Latin Anas, 'duck' and the Philippine island Luzon.
The brown teal is largely nocturnal in habit by dabbling duck standards. This is an evolutionary response to natural diurnal predators such as the New Zealand falcon, Eyles' harrier, or skuas further south in their range. Brown teal have no defense against introduced cats, dogs, stoats & ferrets, which can kill adults & ducklings, or against ...
[78] [154] Divers, diving ducks, penguins and auks pursue their prey underwater, using their wings or feet for propulsion, [69] while aerial predators such as sulids, kingfishers and terns plunge dive after their prey. Flamingos, three species of prion, and some ducks are filter feeders. [155] [156] Geese and dabbling ducks are primarily ...
Ducks eat food sources such as grasses, aquatic plants, fish, insects, small amphibians, worms, and small molluscs. Dabbling ducks feed on the surface of water or on land, or as deep as they can reach by up-ending without completely submerging. [24] Along the edge of the bill, there is a comb-like structure called a pecten. This strains the ...
The harlequin duck (Histrionicus histrionicus) is a small sea duck. It takes its name from Harlequin (Italian Arlecchino, French Arlequin ), a colourfully dressed character in Commedia dell'arte . The species name comes from the Latin word "histrio", meaning "actor".
The ruddy shelduck is a mainly nocturnal bird. [13] It is omnivorous and feeds on grasses, the young shoots of plants, grain and water plants as well as both aquatic and terrestrial invertebrates. On land it grazes on the foliage, in the water it dabbles in the shallows, and at greater depths, it up-ends, but it does not dive. [7]
Black-bellied whistling ducks ingest a wide variety of plant material (including corn, rice, millets, several types of weeds, and other grasses), [17] but also consume arthropods (such as insects and spiders), [17] aquatic invertebrates (such as snails and other molluscs) and tadpoles [17] when available. They often feed on submerged vegetation ...
The white-faced whistling duck (Dendrocygna viduata) is a whistling duck that breeds in sub-Saharan Africa and much of South America. This species is gregarious, and at favoured sites, the flocks of a thousand or more birds arriving at dawn are an impressive sight. As the name implies, these are noisy birds with a clear three-note whistling call.
