“Countability” of Bar-headed Geese in the Netherlands (1 Viewer)

[Byronix]

Hi all,

Not sure which forum this question fits in, but do European authorities consider Bar-headed Geese “countable” for the Netherlands (i.e. a stable, breeding population) or are they treated as escaped exotics? Trying to decide whether to include the one I saw today in my life list. Thanks!

Hmm apparently not. And also not Egyptian Geese, Rose-ringed Parakeets and Rock Pigeons (?!)

Scroll down to page 12. Bar-headed Goose is classed as an established breeding species in the Netherlands and perfectly tickable (legitimately) as an introduced exotic. All Western Palearctic listers tick the species here.

The Dutch however do not count exotics....

The Dutch Birding Association does not include these as countable species.

If you -like the AOU and most other Europeans including the British- have lower standards (by which I mean: you do count established exotics), the table on page 12 of the following report (in Dutch, with English captions) may give you an idea which exotics have populations in the Netherlands (however small):

The only species not in that list is Vinous-throated Parrotbill breeding near Weert in the southeast (it is dealt with later in the report).

Too right, still haven't ticked Pheasant

What about Black Swans? Which countries have established feral populations of them?

New Zealand!
Look at page 12 in the report I linked to: a stable 60-70 pairs in the Netherlands. The Krammer-Volkerak lake is the place to be.

@Joost: Luckily I have now seen Pheasant in Korea, Kazakhstan and China. Not that hard!

The sensible thing to do

We have a couple of Black Swan breeding right here in Southampton along the river...haven't checked their 'official' status though.

Thanks! I think NZ count them as 'reintroduced' as they were apparently native before Maori colonisation left them extinct (probably a subspecies, rather than identical).

Seem to recollect there's some other European countries with feral Black Swans, somewhere one wouldn't have expected - does Serbia ring a bell??

Bar-headed goose in Varanger. Always wondered what was likely to be going on there?! This was about 15 years ago now, July.

Lower standards than who?

Black Swans in the UK too but not counted

In Gemany Black Swan is countable since it's date of establishment (2004)

Other naturalised (therefore countable) species include:
Swan Goose f. domestica (estab. 2016, only population around Heidelberg)
Bar-headed Goose (estab. 2005)
Snow goose (estab. 2011, population around Neuss)
Canada Goose
Egyptian Goose
Ruddy Shellduck
Mandarin Duck
Pheasant
Feral Pigeon
Alexandrine Parakeet (estab. 2012)
Rose-ringed Parakeet
Yellow-headed Amazon (estab. 2010)

Ural Owl too is countable as a sucessfully reintroduced species

Bar-headed geese have bred near Calais at least twenty years ago.

I have an old bird book from the 70's or 80's that has bar-headed geese as a breeding feral population in Sweden.
