hello everyone,

if you are like me, you've probably spent a lot of time pondering what,
exactly, is a species. But if you've ever visited in Germany, you may have
unexpectedly come face-to-face with this very question whilst looking at
birds. Basically, I am talking about the crows in Europe: Carrion and
hooded crows were recently reclassified as full species. Although they do
look dramatically different, carrion crows and hooded crows are almost
indistinguishable behaviorally, morphologically, and genetically, and
hybrid offspring are fertile, but the two forms remain distinct mostly due
to the dominant role of plumage color in mate choice. Is this what makes a
bird species?

I hope you found that piece informative and thought-provoking. I also hope
you share it with your friends and colleagues on social media, especially
facebook and linkedin, and also via that online megaphone, twitter and on
the twitter upstart, MeWe.

thank you for reading.
