-----
It is quite striking to me that of the 40 species of hummingbird which have been lost in European collections over the last 25 years, only four are represented on the Zoochat gallery - especially when one considers that a number of these were present in regularly-visited collections, and present within the last 5-10 years in some cases.
Here, I suspect, there is scope for quite a few old photographs to be uploaded!
