There is often a pair of these doves around the entrance to the arboretum. They have a black crescent around the nape of their neck that is prominently visible against their light, chalky-gray bodies. When they are perched or walking around on the ground, you can see that their wing tips are slightly darker than the rest of the wing.
They mainly forage along the ground for seeds, and they will also eat berries and insects.
This bird was accidentally introduced into the Bahamas in 1974 and by the 1980’s they had made their way over to Florida. Since then they have spread across the United States, except the Northeast where only a few strays have been recorded. In reading about them, I didn’t find anything reporting negative impacts on the populations of native birds.
Cool fact from All About Birds:
”The Eurasian Collared-Dove’s species name, decaocto, comes from Greek mythology. Decaocto was a servant girl transformed into a dove by the gods to escape her unhappy treatment; the dove’s mournful cry recalls her former life.”
