The Colorado Division of Wildlife has announced new regulations for taking of Eurasian Collared Doves. From the Sunday July 11, 2010 Denver Post, Outdoors section "Effective September 01, 2010 hunters may shoot the collared doves year-round". "No bag or possession limits apply, but the doves must remain fully feathered while hunters are in the field or transporting the doves".
The collared dove is one tough, reproducing bird. They stay in my area of the state year round, the coldest of winter temps do not seem to bother them much. Habitat preference seems a little different from Mourning Doves, both town and rural, with a particular liking for large, narley trees, with family units grouped together on the same trees.
With the indigenous Mourning Dove being displaced by the Collared, a more selective shooting of the collaed may be in order.
