It depends on the species, some are highly specialised and eat only crustaceans or fish, at the other extreme, most of the common species seen around human habitation are total omnivores, eating almost anything edible.
YouTube has a video of Orcas (Killer whales) "playing" with a pelican, so I know that Orcas would eat gulls. Also, many types of shark eat gulls. Iguanas eat theirs eggs when found on shore-based nests.

Anything they want pretty much
A sea gull would be hard pressed to prey on sparrows. The smaller bird always has the advantage when it comes to evasive maneouvres. The Sea gull is not equiped with talons or a beak to catch anything with. It is hard to imagine a Gull holding onto anything. If a sparrow were already dead then a Gull would eat it though.
The term, sea gull, is a common collective name for several individual gull species. Taking the Herring Gull and the Black Headed Gull as two examples, these gulls that will eat practically anything, from scraps of bread to anything meaty it can find on a rubbish tip. Therefore, some gull species are more omnivore in their eating habits.
Just about anything fish or even small rodents.
