    Introduced birds in Europe

    Ruddy Shelduck is naturalized in Switzerland. Unless it had a collection ring, it should be countable. Not the ringed teal, though. Going just slightly off topic. Anybody knows recent counts and history of escaped parrots on Tenerife? It was really amusing to see a morning flight of a dozen of...

    Introduced birds in Europe

    There is no standard what counts as established feral population. Muscovy population in the Netherlands counted as wild for some time. It made sense, because there were many groups of domestic Muscovies in Randstadt megalopolis (Amsterdam-Rotterdam), which has no poultry owners and lacks...

    For interest: records of Cackling Goose in The Netherlands in summer 2018., showing how widespread is feral population. Scan from waarneming.nl. It is a nice complement for e.g. records in Britain. (Waarneming used to be able to select only actual breeding records, but unfortunately this...

    Introduced birds in Europe

    Hi, Neither I know why Swiss want to get rid of Ruddy Shelduck (and if this shooting plan really is realised). But Ruddy Shelduck is common as muck in Central Asia and India, so I don't think it has any conservation significance.

    Introduced birds in Europe

    Hi, Why Ruddy Shelduck in Italy are not feral birds from Switzerland? Feral population is closer than a wild one. And, as far as I recall, Balkan population is rather small.

    Introduced birds in Europe

    of top of my head: Breeding parrotbills were also reported from Holland some years ago. Erckel's (?) Francolin is said to be in Italy (Paul?), Mandarin - Germany, Poland - this for sure and countable Chilean Flamingo - Germany, maybe Carribean is established now also. Spain has several...
