From late March until October maybe, they fly off to Africa for winter, though I'm sure if I was a nightingale I'd prefer to be here, but there's probably not the insects about to keep them fed. I usually hear them when I'm walking the dog as it's a very quiet neighbourhood where I live. I have seen them from my kitchen window, along with Sardinian warblers, hoopoe, chiffchaff, spotted flycatchers, bluethroats and goldcrest, as well as blue tits, sparrows, blackbirds and starlings of course.
