I've seen pretty much the same discussion about capitalisation in Dutch. Birders capitalise bird names, which is wrong grammatically, but makes them more obvious in texts (a capital will usually trigger a response). You could defend the view that the names of taxa are names like Harry, Dick and Tom, and should therefore be capitalised. However, if you write to non-birders about your sightings, it's better to leave out capitals, because they will get annoyed!
