Anyone good at Mio-Plio bird ID?

[hemipristis]

Hafa adai everyone, greetings from Guam!

 

Been sortin' through the collection and came across my Lee Creek bird finds. I have about a half-dozen bird vertebra. Does anyone know anyone who might be able to ID?  I also have a large-ish bird vert from Calvert Cliffs.

 

Thanks in advance!

Pease post pictures a number of species exist with Auk (Alca sp) being one of the most common in Lee Creek.

There are a number of people here who may be able help.   

Please post some well lit, detailed images of the fossils in question, with a ruler in each shot for scale.

Here's the first vertebra. I took photos from the top onto the spinal process, bottom, 1 lateral view, and both ends of the vertebra body.  This is from Lee Creek, Pliocene Yorktown Fm. Photos in order: Top, Top (rotated 180), Bottom, Lateral, End 1, End 2, Angular

This next vertebra is from Brownie's Beach, MD., Miocene.   In order: Top, Bottom, End 1, End 2, Lateral 1, Lateral 2, Angular looking from below, Angular looking from above

Last one for the day. I'm guessing this is a vertebra, though there wasn't a central spinous process. I thought it rather large for a bird. At the time I found it (Lee Creek, Pliocene Yorktown Fm), someone mentioned Pelicornis, but I dunno if that's accurate or not.  Photos: "Top", "Bottom", End 1, End 2, Lateral 1, Lateral 2, Along the length looking from one end.

The second one looks like a mammal C2... axis.

Any more thoughts on these?

Yes, the second can be axis from canid or felid, I have found one fox axis in Lithuanian Pleistocene two years ago and looks very similar.  

The other bones belong to bird and are quite big, so why could not be from Alcidae.
