Seagulls or Pigeons?

I don't know which, but this group was shopping at the Sam's Club in NRH a couple of weeks back.

It appears that a couple of them, with a good dry rub of jalapeño and sage, and wrapped in bacon, could make a meal.  They're huge.

I tried to find some info on the interwebs, but it didn't help much:

Gulls are a taxonomic family while 'sea-gulls' are a generalisation based on morphological similarities in predominantly coastal and pelagic gull species.

The term ''sea gull' is erroneously used to describe many species of gull seen in both coastal and inland habitats. The gulls most commonly referred to as sea-gulls in the UK include the herring gull, the lesser black-backed gull and the greater black-backed gull. Worldwide there are probably many more such generalisations.

Pigeons are near-passerine (perching) birds and are not related to gulls except in the most distant sense.

I think they look like gulls.  Maybe David Lee Roth knows...
