Cow Birds, Blue Jays, Scrub Jays and Steller's Jays are infamous for this behavior. Birds of many species will steal nests, nesting material, nesting hollows, food, and "partners", of their own and other species (not usually the partners of other species but hybrids do occur). They will also steal or merely destroy the bowers (constructions built by a male bower bird to to advertise his fitness to females) of competing males.
It's a cost benefit ratio. If the species has a breeding system in which there is a net gain in reproductive fitness for some individuals if they steal the nest of another individual, then some individuals of that species are likely to do so.
