    AOU-NACC Proposals 2020

    Thank you, Andy. Just curious -is there a limit to the number of "rounds" and do you happen to have an idea when this case might be decided/announced?

    AOU-NACC Proposals 2020

    Thank you - I did not realize that was a nuclear tree. I knew that its inclusion was to support their conclusions about Royal Tern, I was just surprised that the weird branch was barely mentioned in the paper. Hopefully they can publish something interesting on the Cabot's/Elegant clade as...

    AOU-NACC Proposals 2020

    The Collinson data is mtDNA too, however, and it has elegans and eurygnathus all mixed in their node - that's what I can't resolve. If Elegant and Cabot's are so distinct from one another, how did Collinson come up with that tree? I get it that the bootstrap values are very very low, but they...

    Thank you for this, Laurent, and for the interesting conjecture about hybrids below. I think I was thinking in smaller scale when talking about the bill colors; I was focusing more on just the Sandwich/Cabot's/Elegant node, in which dark bills might be basal and orange/yellow would be derived...

    AOU-NACC Proposals 2020

    So how then does this resolve in relation to species limits? It would seem that there is maybe a half to a million years of divergence, but also rife with crossbreeding? Or something more complicated? The Collinson data have the appearance of either that or orange bills evolving several times...

    AOU-NACC Proposals 2020

    I noticed this too - one of my initial reactions to this proposal is that it seemed a "backdoor" way to get a Cabot's Tern split... or in other words if this gets accepted, then its acceptance could be used as further evidence to revisit that one. Note also that there is a point where the...
