Aquatic Warbler is
a rare autumn passage migrant between August and September
usually recorded at a few favoured sites where on average a
total of about forty birds per annum are reported in the UK. It
is restricted as a breeding bird to a few places in Poland and
Hungary where they apparently very difficult to find. There are
between three and eight thousand pairs with about 90% of these
in Poland. Smaller numbers still breed in Hungary, Germany, the
Baltic States and the Ukraine.
