There are 2 extant races of Garden Warblers, which are a strongly
migratory species.
Nominate race
"borin"
breeds in much of Europe.
Race
"woodwardi"
breeds further to the East, from eastern and south-eastern Europe
to temperate central Asia.
They overwinter in tropical to subtropical southern Africa (except South
Africa).
Anywhere in between tropical Africa and central Europe they are found
only on migration.
In Europe Garden Warblers, nominate race
"borin",
are summer breeding migrants to western, central and northern
Europe. They are also found basically all over Britain and in
small parts of Ireland. On the continent, their range extends
from the northern half of Iberia, all of central Europe north
of the Alps, Scandinavia except the Kola peninsula, up to
eastern Europe, to a line connecting roughly Finland with
Hungary and Bosnia.
Further to the East, race
"woodwardi"
is found.
Garden Warblers have a strong preference for forests and woodland
with tall trees and dense, shrubby undergrowth. They are often
found on the edges of wooded areas, in low, dense fringe growth,
or around clearings. They will also stay in parks and gardens with
such dense undergrowth.
