Anyone keeping and breeding hummingbirds in Netherlands ? There was one breeder from Netherlands, namely Jack Roovers who successfully bred hummingbirds in captivity in past. Mr. Jack Roovers had a site which can be accessed here: https://web.archive.org/web/20120717220551/http://www.jack-roovers-hummingbirds.nl/ Please share your knowledge about the breeders you know.
As you mentioned was, Jack Roovers past away a few years ago sadly. Only avifauna kept some species for a few years but seems to have lost them. I haven't heard of many hummingbird species being bred in Holland, but there still a few Europeans who do.
