The roach vireo ( Vireo olivaceus ) is an American songbird in the vireo family . Two subspecies, including the nominate form, occur in North America, about ten more subspecies live in Central and South America. It is one of the most common forest bird species in North America. According to the Guinness Book of Records , it is the bird that sings most of the different songs, sometimes over 2,000 different songs per hour.
The roach vireo is a rare guest bird in Europe. However, since the 1970s it has been recorded annually in Great Britain and Ireland and is the most common Nearctic songbird species to be observed there. In Central Europe he is an exceptional guest who has only been proven a few times so far.

Occurrence
The roach vireo is a nearctic and neotropically widespread breeding bird of the boreal, nemoral and subtropical zones from North America to the middle of South America.
The bird breeds in forests and sparse woodlands in much of Canada and the United States . To hibernate, he moves south to Uruguay .
behavior
The roach vireo hides in the treetops, but catches the eye with its song during the breeding season. In autumn and winter the bird feeds on fruits and berries, during most of the year mainly on insects.
