Which green bird with a loud call, which hollows out old trunks to nest, frequents the trees of the cemetery?
The answer
The green woodpecker needs dead wood: it hollows out its nesting hole there and hunts for the ants it feeds on. Since dead or hollow trees have stopped being routinely felled at Père-Lachaise, its laughing call can be heard from one path to the next — a cry that carries for hundreds of metres.
This question belongs to the “The Animals of Père-Lachaise” series of the Père-Lachaise quiz: ten questions, a story behind every right answer.
