Seedsnipes are a little known bird-family from the Andeans in South America and only 4 species are known. They have been only rarely kept in captivity and I know of only 2 collections having kept the Little seedsnipe. At Walsrode I´ve taken care for 2 males and 1 female and a Belgium friend kept some during the 1970-ties - 1980-ties. Breeding-results are completly unknown to me. Does any-one know of other collections having kept - or maybe even bred - seedsnipes ?
In the old Guide (from the eighties. ?) from english bird park Birdland in Bourton-on-the-Water, I found a photograph of a male Least Seedsnipe (Thinocorus rumicivorus). Unfortunately, except for the name, nothing is stated about this species in the collection.
By looking through old Zoonooz-magazines I found the issue of Sept. 1980 in which the San Diego Zoo mentions that they obtained 4 Leasst Seedsnipes. On the picture by the article a male of this species can be seen.
I think imported birds were briefly in the trade in the 1970s. There was an article in Cage & Aviary Birds at the time. Sure nobody ever bred them.
if I remember right, Frank Woolham's book "The Handbook Of Aviculture" had a section for seedsnipe, complete with photo (presumably a least seedsnipe, I can't remember that much though).
An intresting article about wild seedsnipes : http://www.ararajuba.org.br/sbo/ararajuba/artigos/Volume204/RBO204not3.pdf

Thanks animal explorer but I made this photo myself ( end of the 1980-ties ), I took care for them myself and posted the picture myself .
