A dove has built its nest in front of the red traffic light at a roundabout in Essex.
The bird moved into its new home at Cuckoo Corner in Southend, despite the lights having anti-bird spikes fitted.
The RSPB said the collared dove was facing traffic coming from Priory Crescent and the light would provide heat.
Frank Varga, RSPB officer, said: "It's happy and using the deterrent to support its nest, so well done."
The roundabout is also fed by Manor's Way, Victoria Road and Prince Avenue and has 21 traffic lights.
The RSPB said the collared dove is used to nesting on cliffs
"This is a perfect area with plenty of grassland including Priory Park nearby as a resource for food," Mr Varga said.
"From its origins in Turkey the collared dove has colonised the whole of Europe since the 1930s and my guess is she saw this spot and managed to move the spikes slightly to build the nest.
"In the wild, these birds live on cliffs so it's replacing the noise of all the other birds with the noise of traffic."
It is thought the dove moved in a fortnight ago.
