I love seeing African birds here--it gives me something to actually answer. Yes, this bird looks very good for a Southern Grey Headed Sparrow as mentioned above

Hi, These were taken at the Port of Ensenada in Baja. I know I'm looking at some western gulls, but is there anything else pictured? --many thanks!

Okay, North American birds aren't my specialty but let me just throw out Northern Gannet. I also struggle to see this as a gull but think the Gannet might match the OP's description a bit better than a petrel.

Yes, green-winged Pytilia

This is a female Village Weaver with that dark bill and red eye.

Agreed--I think we can be reasonably confident that this is a Hooded Vulture. Even backlit to hell, a Cape Griffon shouldn't be that dark. Then, when you factor it the long curved bill, I'm comfortable calling this as Hooded.

Yes, this is certainly an immature Bateleur

Jumping into the threat after a long time. This is a female/non-breeding Southern Masked Weaver

Agree with Northern Red.

Definitely a Cape Wagtail!

Agree with the other comments: I think your drab birds are Swainson's/Parrot-billed Sparrows. Though the bill in the middle picture is throwing me a bit...it has a fiscal quality that I can't quite place.
