Choughs and red-billed choughs

A flight of black birds twists and turns before descending on the alpine meadows. The choughs are seeking out meagre takings, preferably small invertebrates. Great acrobats and sociable birds, they stand out with their yellow beaks and red legs. Sometimes a few red-billed choughs mingle with them. These are more timid and have a red beak and red legs. Both species nest on cliffs.
