While I love that website, I am leery of considering a taxonomic checklist created and run by only one individual and only in an online format to really count as any sort of "official" checklist.And then there's the "best"of the lot: taxonomy in flux... Seriously, though, there will never be nor should there ever be one taxonomy. Ideally you'll not just tick the birds off but learn about them. So you'll appreciate Cassia crossbill whether or not you agree it's a species and you'll be aware of what makes it special.
