i don´t have flu!
****************************
The Mallard (Anas platyrhynchos)
is a common and widespread dabbling duck which breeds
throughout the temperate and sub-tropical areas of
North America, Europe and Asia. It also frequents
Central America and the Caribbean. It is probably the
best-known of all ducks.
This dabbling duck is 56-65 cm length, with an 81–98
cm wingspan, and weighs 750–1000 g. It is strongly
migratory in the northern parts of its breeding range,
and winters farther south. It is highly gregarious
outside of the breeding season and will form large
flocks. They are exceptionally fast flyers for their
size, reaching speeds of 40mph. Due to their
streamlining however, it hardly ruffles a feather.
The breeding male is unmistakable, with a green head,
black rear end and a blue speculum edged with white,
obvious in flight or at rest. Males also possess a
yellow bill with a black tip, whereas females have a
dark brown bill.
*****************
Avian flu or Bird flu or Avian influenza virus refers
to a subset of Orthomyxoviridae that creates influenza
in birds and are endemic in birds.
The species of Orthomyxoviridae that can cause flu in
birds is influenza A virus. All subtypes of it infect
birds so for many purposes bird flu or avian flu virus
is influenza A virus (the "A" does not stand
for "avian").
However most people use "bird flu" to mean H5N1 which
is the subtype of the species influenza A virus that
is a current pandemic threat. |

I've seen these Headless Ducks (Anus headusdecapatus) before, you have done an excellent job at rediscovering the species. Well done Thorsten. :)
