Does anyone know studies carried out on breeding birds living on the internal ridges and slopes of coenotes (karstic sink-holes with top hopening)? To my knowledge, there are only short notes on occasional presence of birds living in vertical slopes (characterized by reduced brightness). Since I carried out a research with mapping method in the Pozzo del Merro coenote (a 70m-depth karstic cavity), I would like my data with others in literature. Thanks. corrado

ciao Corrado!
I do remember a booklet on Pyrrocorax pyrrocorax, written by Sandro Lovari, on the breeding habitat of the species, that was almost invariably located in sinkholes. The booklet was published by the Abruzzo National Park, I don't have other details at present, but if you are unable to find it, I can search in my library,
regards,
Guido
