Bibliography

Comment by the expert

Roberto Reis: Fair description of BIN, but few photos or videos. Good description of threats.

Francesco Denitto: Very sparse BIN description. Just few basic information about threats were given.

Donald C. Taphorn: The GBIF link just goes to a general page, not your specific subjects. So you could have found a better source for info on your species, and gotten more details about each, as well as still photos of each, and at least a paragraph describing each of them, things like whether they are rare or common, what they eat, etc.
