People in Gloucester are being invited to get up early to listen to urban birds singing at dawn.
Countryside rangers from the city council are offering to take groups out to hear the dawn chorus and explain which species are taking part.
There will also be an event one evening in Quedgeley for those who cannot face an early morning.
Ranger Derek Wakefield-Brown said: "At this time of year the dawn chorus is one of nature's brilliant events."
For people who want to listen to the early chorus, the event takes place at Alney Island on 2 May at 0500 BST.
The evening event is on 28 April at 1940 BST and starts from Quedgeley Library.
