The birds pictured below are the Dunnock, the Eurasian Wren, and the Common Wood Pidgeon. The dunnock is one of the most widespread birds in Rome. This distribution is due to their versatility in nesting sites, which include hedges, shrubs, gardens, forest floors, and many other areas. They often hide in hedgerows, which is how they got the nickname Hedge Sparrow. Although it's tiny, the Eurasian Wren is one of the loudest songbirds in Italy. They are found in Rome with plenty of areas to hide, like thick forests and gardens. They're primarily insectivores but occasionally eat berries or seeds when insects are scarce. Their scientific name, Troglodytes, actually means cave dweller, because they like to live in small holes. The wood pidgeon is the largest found in Italy, and they spend most of their time in trees. However, they prefer to nest on flat surfaces like building ledges or even the ground. They're found in large flocks in the city.
