Just a first impression from the families list. What they seem to have
done is moved anything odd or anomalous out of the families they were
previously lumped into into their own families. The problem with this
is that anything odd or anomalous is subject to disproportionate
attention from the DNA-wizards, but it's quite likely that other spp
that look similar to other members of the family they are currently
located in are also not closely-related and are also deserving of
separating. By the the time they are finished they could end up with
400-500 families!

> A major new revision of the IOC World Checklist is now available as free
> Excel file; it includes 33 new families, most of them long anticipated, and
> covers some 10331 species, the first time the magic 10,000 barrier has been
> passed.
> Australian and New Guinea common names are still out of sync with what is
> actually used over here, but this is being addressed for the next update. I
> can recommend this checklist as a useful and progressive step on the long
> road to unravelling bird relationships
> Here's summary:
> This is a first step towards aligning the IOC list of 10,331 world bird
> species with published molecular phylogenies, especially those of the last
> three years that feature strong taxonomic sampling and multiple gene
> sequences. Some changes of sequence in the list were essential, but we defer
> major sequence changes to allow time for improved stability. Major features
> of realignment include:
> 1.     Separation of 9 additional Orders, bringing the total recognized to
> 42
> 2.     Separation of 8 additional families of nonpasserine birds, and 25
> families of passerine birds (4 suboscine, 21 oscine), bringing the total
> number of families recognized to 226.
> The IOC World Bird Names Website    has
> been updated.  List 2.0 contains 10,331 species classified in 42 Orders,
> 226 Families and 2199 Genera.  This is a major update that includes
> revisions of the family classification as well as species taxonomy.   It is
> the first step in aligning the world list with advances in understanding
> the evolutionary relationships of birds based on the recent surge of DNA
> studies.  Among other changes, the list now includes revisions of the Old
> World Warbler Families, and a resequencing of suboscine families to align
> with South American Checklist Committee classification.  We invite you to
> explore the list, hope you find it useful and welcome your feedback.
