Muscovy Duck Cairina moschata
The wild Muscovy duck originates in the wooded wetlands of South America, where both sexes are a similar, glossy-black colour with a greenish/purplish gloss and some white on the wings.
The domesticated Muscovy duck is much heavier, with larger carbuncles ( the fleshy growth around the eyes ), and occurs in a variety of colours including black and white, and lavender and white. The drake is larger than the female, with an erectile crest and mane, and prominent facial " warts ". They are common domestic birds throughout many parts of the world including Africa.
In the wild, they commonly roost in trees and even spend some of the daytime perched in trees. In captivity, they sometimes make their nests above the ground in holes in trees, barns or even in nest-boxes erected for species such as owls or jackdaws.
Food is mainly vegetable, but close perusal of our birds will soon show them ( especially the ducklings ) pursuing all manner of insects which chance by. In the wild they are known to break open the nests of termites with their powerful beaks.
Generally speaking these ducks are not vocal. The ducks utter a soft quack when communicating with their ducklings. The drakes hiss, especially when threatened or displaying to other males or females. At these times, the male engages in a rhythmic bobbing of the head forwards and backwards, with neck outstretched, crest raised and wings partially raised. The long tail is vibrated in a manner which appears like " wagging " to us.
Lesser Bahama Pintail or White-cheeked Pintail
Anas bahamensis bahamensis
A very popular species in water fowl collections, which is now found in several colour varieties. The sexes are fairly similar in plumage, but the drake is larger than the duck.
The main features are the diagnostic, white cheeks and the typical, long-pointed or " pin " tail.
If you are lucky, you may see the drake display to the female by vigorous head-shakes, then tilting forward in the water and, peacock-like spreading his tiny tail whilst tucking his head and neck back. Females also display to encourage their mates.
Although hardy in the UK, in the wild this pintail is found only in tropical and sub-tropical regions of America. It breeds in the Bahamas, Cuba, Hispaniola, and the Lesser Antilles, south to Guadeloupe, Curacao, Trinidad, Guyana, Surinam, French Guiana, and North Brazil.
Numbers are now decreasing throughout its range due to excessive hunting and poaching.
It's preferred habitat is well-vegetated fresh water ponds and swamps where it feeds on all sorts of plant matter - roots, stems, and seeds - with some aquatic insects and snails.
Proposed Cull of Ruddy Ducks
A government sponsored cull of Ruddy Ducks is about to start in Britain, with the Scottish end focused on Kilconquhar Loch, in Fife.
This "avian ethnic cleansing" is designed - wrongly in my view - to reduce or eliminate the spread of this harmless little North American Diving Duck.
The bird has now spread all over Western Europe and is threatening to genetically take over by interbreeding with the closely-related and highly-endangered Whiteheaded Duck in Spain.
This particular population is probably a lost cause.
What conservationists are, however, desperate to prevent quite understandably - is the Eastern spread of the Ruddy Duck into the countries of the former Soviet Bloc, but in this they are also probably too late.
This little duck is already happily ensconced in countries like Slovakia and Romania and merrily fraternising with the natives, in this case, once again, the Whiteheaded Duck.
But why is a cull of this attractive little duck in Scotland justified?
It is inadequate, as one RSPB spokesman claimed, to state that: "It is all very unfortunate, but it's a classic example of how it's better if you don't move the world's wildlife around.
"If you leave it where it has evolved naturally over thousands of years then a balance is reached.
"That balance is being upset here and that's whv we must do something about it." I am not alone in believing this effort to be futile and unjustified.
