In a total of 61 days, with a total effort of 283.45 hours, were counted 7916 individuals for a total of 23 species of birds of prey observed, which leads to a daily index of 129.8 indd./day.

Gli Uccelli di Pratorondanino

Gianni Lucchi, Daniele Baroni & Giuseppe Valeri

Abstract – The birds of Pratorondanino. In a three-year period (2012 2014) we studied the birds of an area of 75 hectares surrounding the “Pratorondanino” botanical garden in Ligurian Appennine. We found 75 species, with a rich community of woodland birds typical of mature forests. Open habitats (equine pastures and marshy fields) offer food resources both in winter (Common Snipe, Hen Harrier, Meadow Pipit) and in breeding period (Barn Swallow, Tree Pipit, Yellowhammer). The Black Woodpecker breeds in the study area as a result of a recent eastward expansion in Ligurian Appennine. We confirm nesting of the Red Crossbill in May. These data on bird diversity of Pratorondanino will help the naturalistic promotion of the area, following previous surveys on plants, dragonflies, reptiles and amphibians.
