Bird identifications needed

We were down at St Govan's Head today and saw some birds we couldn't identify, so if anyone can help, please do...
Apologies for the terrible quality - I only had a 200mm lens and 1.4x converter, and could barely see them, so these are 1-1 pixel crops.
It was only when looking at the photos I noticed there were actually two different bird species.
