Yellow-billed Teal Anas flavirostris Scientific name definitions

The Yellow-billed Teal is a common duck of southern South America.  The species shows the compact proportions typical of teal and is gray below and brown above with a dark brown head and yellow bill.  Overall Yellow-billed Teal look like a darker, smaller and less elegant version of the widely sympatric Yellow-billed Pintail.  Birds from the high altiplano are pale silvery below, whereas the lowland race is darker grayish brown.  In flight and when excited, males give a creaky "peeet" call and females quack, also typical of teal.
