Personally, I have chosen the option with 5 genera (Hydrobates, Cymochorea, Halocyptena, Oceanodroma and Thalobata)Honest question from a non-scientist: John Boyd treats Hydrobatidae in 4 genera, which I like, but leaves furcatus in Hydrobates. Why not leave a monotypic Oceanodroma as sister to Hydrobates? From what little I know of these two (and I have no field experience), furcatus certainly seems very distinct from pelagicus (larger size and very different calls, even more divergent from pelagicus than Cymochorea or Thalobata species, in my opinion anyway). As I'm blind, it's possible I'm overlooking plumage similarities. The only other explanation that makes sense to me is that the divergence times between pelagicus and furcatus are more akin to those within Cymochorea, for example, than to those between the broad clades...
We can't escape monotypic genera, so they might as well get used to itSome taxonomists try and avoid monotypic genera.
