Goldeneye is not a brood parasite. Where are cowbirds and black-headed ducks established? I know the duck used to be in Slimbridge, but that was a long time ago that I saw it there.
Are These in Captivity? #2
- Thread starter The Cassowary
- Start date
Whydahs and indigobirds are available on the private trade and sometimes kept in zoos. They're also bred in captivity even though it is no easy task.
Black-headed ducks are not really established, they've been in Köln for a year and I don't know about the one(s) in Slimbridge.

Judging by a quick search, cowbirds are kept by a handful of US zoos and black headed ducks at Slimbridge.
There is definitely nest parasitism with the golden eye duck.
In Australian aviculture several whydah-species are well-established.
They don't - I spent a very enjoyable afternoon some time ago updating the ZTL listings and making them fully accurate after I was provided with a then-current stocklist by someone with ZIMS access, was thanked by the ZTL admins, only to be scolded by the ZTL admins several days later after Walsrode complained to them that an accurate stocklist was visible to the publiccue all my work being reverted and the listings being actively made inaccurate (including moving species back into current holdings which had left the collection years before).
So I think we can be fairly certain that Walsrode would be loathe to publish a stocklist anytime soon given said reaction
Has anyone (besides Joel Sartore) successfully convinced Walsrode to show them the off-exhibit birds?
Yes but nest parasitism within the same species, females may lay their eggs in other female's nests.

Yes, true, intraspecific nest parasitism.
Therefore the females are able to raise their own youngs, unlike other parasitic species, that's why the species is so common in captivity I believe.

Yes, I agree that has definitely facilitated the keeping of the species in captivity and that it may be more difficult in the case of interspecific brood parasites but even if through intraspecific parasitism the golden eye is still classed as a brood parasite.
If we are counting intraspecific brood parasitism, then the list of non brood parasitic species is minimal!
Was probably around 18 months ago now.
Were I to guess as to a motive, there's probably some overlap with the reason I have heard through the grapevine that (despite many repeated assurances that once the migration from ISIS to ZIMS was complete it would once again be free-to-access as it always had been in the past) the decision was taken by Species360 to block laypeople from seeing such records in the first place..... to wit, pressure from collections (especially in the USA from what I have been told) who were of the opinion that allowing non-professionals to see accurate listings of what species they held was tantamount to inviting theft-to-order of their stock.
What do you mean by "theft-to-order?" Is that like cattle rustlers but for zoo animals?

Not sure if this has already been asked, but are there any Mona Island iguana in captivity ?
Not in Europe at least, however, the nominate subspecies of the Rhinoceros iguana is kept by at least 78 facilities in Europe.

Yep, no shortage of rhino iguanas in zoos but the Mona Island iguana doesn't appear to be kept anywhere, maybe in a facility in the US ?
Not that I know of.
Can't say I've heard of any.

Maybe Zoodom in the Dominican Republic or perhaps a facility in Puerto Rico.
I know that both the "Iguana Conservation Foundation" and "Island Conservation" which are US based NGO's work heavily with ecosystem restoration and species conservation with the iguana on Mona Island so it would be suprising if the species isn't held ex-situ somewhere and probably the USA.
Any handfish other than Spotted Handfish and Red Handfish in captivity? Also any Red Handfish other than at Seahorse World?
There was a paper written on involvement of zoos with Caribbean iguana conservation, which mentioned that the Toledo Zoo worked with the Mona Island iguana in situ; it made no reference to there being a captive population for it, unlike other species like Grand Cayman.
