The Eurasian Collared Dove looks very similar to the Mourning Dove. They were introduced 40 years ago and have spread throughout North America. We get a few Pigeons but they tend not to hang around. Recently saw the Rock Pigeon which had a band on its leg – I wonder if he belonged to someone. In 2019 there seems to be a nest as we have had 2 Doves with us for quite some time.
