The main argument in support of technical names is of course their stability compared to common names, but this is often overly exaggerated by books on natural history. In reality, splits, lumps and preference can make old and trusted names invalid. I was recently looking through some documents, posted on this very site, which were from 1883 and obviously had many names invalid today. The vast majority were quickly resolved using ITIS, GBIF, Wikipedia’s synonym lists and similar, but a few escape my attempts to identify them. Many have very confusing common names as well, making identification harder. Here they are: ‘Himalayan Black-bird, Merula bulbul’ Cacatua ‘cristata, the greater White-crested Cockatoo’ ‘Treron viridis, Parrot fruit-pigeon’ ‘the small cat from Java, Felis javanica, which is a miniature representation of the fishing cat of Bengal’ as well as a reference to a ‘black-backed goose’ with no scientific name given (Canada geese are given later, but ‘black-backed’?). I am particularly intrigued by ‘Felis javanica’ as it could be a reference to the Javan fishing cat, which was supposedly only described in 1936 according to Wikipedia, but online search brings up nothing. In all honestly, this is probably too trivial a question to create an entire thread, so if anyone faces similar problems in the future feel free to use this as a place to put your questions.
