Friday mystery object #216

I hope you all had an enjoyable Yuletide, I’ve certainly been glad of the excuse for a lie-in over the last few days.

The mystery object is a bit late today, but I hope you’ll forgive me in light of the general seasonal torpor.

Here’s a sternum that I’ve been puzzling over for a while – I can make a pretty good guess at the family it comes from, but I’m less sure of the species:


I’d appreciate seeing what you think it might be – let’s see if we can work this out!

  1. Perhaps about the size of a feral pigeon and from the shape of the keel I think it’s more of a gliding/soaring bird than a flapper.

    The posterior end of the sternum is double notched.

    Wild guess: Storm Petrel (though that may be too large).

  2. The double-notched posterior edge and the relatively shallow keel all point toward seabirds. I’m looking around. But, I wanted to say that I will be expecting my students to follow this blog this term. The observational quality of its participants is unparalleled. Best to all in the New Year!

    • Thanks Daniel, I hadn’t considered seabirds, I was thinking along the same lines as Jake. I’ll see if I can find some more seabirds for comparison.

      As to the observational quality of the participants I’d have to agree – the contributors are what makes it worthwhile running the blog!
