This is the second edition of my personal adaptation of the excellent on-line “Taxonomy in Flux” (TiF) checklist. Whilst it’s based on the current list as above, it's a very much simplified version just showing the 110 non-passerine families grouped within their taxonomically re-sequenced orders (see the December 2016 entry on my 'taxonomy updates record'
). There are a further 138 families within the order PASSERIFORMES but, as I will encounter very few of these, I have deliberately omitted them. I may produce a separate list at some point in the future, but for now I want to concentrate on the non-passerine species featured within my various bird photo ‘collections’. In this respect, I found it useful to have an abridged and re-ordered version as well just for the orders and families of those species that I’m featuring. That particular listing can be found here
I’ve made a number of references to the TiF system on this website as I have found it such a useful resource. As its name suggests, "Taxonomy in Flux"
is constantly being updated by its American author, Professor John Boyd, who keeps the checklist one step, or more, in front of the four primary lists, namely those maintained by Cornell - eBird/Clements, BirdLife International, Howard & Moore, and the IOC (International Ornithological Congress) who update their version quarterly. Whilst the TiF system isn’t formally recognised in the same way, it is still very well regarded by all the main authorities.
The list separates a number of species and families where recent studies show that they should be moved out of certain traditional orders. It also re-evaluates and splits groups of similar species, such as long-legged waterbirds. The final result is an extended list of 46 orders, all of which are listed below.
