It is an Orchard oriole first summer male. You can read more about them at: http://www.allaboutbirds.org/guide/Orchard_Oriole/id. Second year males are similar to adult females, but have a solid black bib and black between the eye and bill. How much black adult plumage varies considerably between individuals, with some males of this age having blacker feathering than others.
Adult males are black above and rich reddish-chestnut below. They have a black head and throat, with a reddish-chestnut patch at the bend of the wing. Females are greenish yellow with two white wing bars and no black.
Orchard Orioles eat about the same thing as Baltimore Orioles. They like nectar, slices of oranges or offerings of fruit jelly (although provide small amounts at a time so it doesn’t get too messy). They are also insectivores, so a shrubby backyard may provide enough insects and spiders to attract them.
