Bird skull identification please

Hello,

 

Here are some photos of a skull that I found on Chesil Beach, Dorset a few weeks ago.

 

The closest matches that we can find so far are Red-breasted Merganser or Shag, which I found on this rather impressive website http://www.skullsite.com/index.htm . However some differences, eg. the detail at the back of the cranium, mean that we’re not quite convinced.

 

This specimen’s vital stats:

Cranium length - 53mm

Cranium width – 31mm

Bill length (incomplete) – 52mm

 

Any further id assistance in solving this gratefully received.

 

Thanks,

 

Chris

      Hello,

      Skullsite is an excellent ressource ad I use it in such cases as your specimen. I'm sure its a Shag skull. The next closest match would be the Cormorant, only larger and different shape, sagital crest, etc. Mergansers are ducks, just look at their large nostrils in the middle of the bill and you will dismiss this group. Compare with other possible groups: divers, grebes, gulls, but the general structure is very different. Gannets are actually the closest match outside the cormorant group, but not quite. I say Shag, Phalacrocorax aristotelis. (not aristoteles - wrong name on skullsite)
