She often sits there feeding the little birds.
Literal
She [topic-は] little-birds [to-に] food [object-を] giving [while-ながら], often there [at-に] is-sitting.
えさをやる ('to give food to animals') uses やる, the casual form of あげる appropriate for animals and children. The ~ながら connects two simultaneous actions: feeding birds while sitting. よく ('often') indicates this is a regular habit. The ~ている at the end marks an ongoing habitual action rather than a single instance. A warm, pastoral scene.
