hi all i wondered why only canaries get a nest full of mites and not other birds i found this on an american website
Though fleas and lice are opportunists, they tend to gravitate towards, and specialize in, certain hosts. Different species of bird lice, for example, specialize in different species of birds. In fact, many species of bird lice can only be found on very specific bird species. The extinction of a bird species may, in turn, result in the extinction of one or more species-specific types of bird lice.
