Collared doves (Streptopelia decaocto) are a pale, pinky-brown grey colour, with a distinctive black neck collar (as the name suggests). They have deep red eyes and reddish feet. Adults can be distinguished from juveniles by the narrow black and white band round the back of the neck (which juveniles lack). The Collared Dove feeds mainly on cereal grain and small seeds on the ground, but will also eat berries in the autumn and, more rarely, caterpillars and aphids in the spring.
