The Swiss
RC also maintains the list of the birds of Switzerland with AERC categories.
The AERC recommends that each European country collects information
about birds escaped from captivity. The Swiss Ornithological
Institute is responsible for collecting such data in Switzerland
and maintaining a list of species escaped from captivity. Note
that those reports are not checked by the Swiss RC. However,
if you see a species obviously escaped from captivity which is
not on the list, please write a description or take some photographs
(it is often easy with escaped wildfowl). Some species on this
list were also recorded in Switzerland as wild birds (for example
Cattle Egret, Ring-necked Duck, etc.).
