I spent two summers in an apartment in San Francisco that was near the nest of what I assume was a nightingale.
Every night around midnight it would start singing. It would loop through maybe 8 songs. Some of them sounded very much like the local environment. For example one song was pretty much identical to sirens that I would periodically hear.
It would last for an hour or two each night. I don’t know where the bird went the rest of the year. That was almost ten years ago and I still miss falling asleep to that.
The Lyrebird from Australia is probably the best at this. It can imitate just about anything - car alarms, other birdsongs, camera shutters, gunshots, etc. etc.
