Spread Rate
Extremely successful colonizers and breeders, spreading prolifically in the 1980's throughout FL and SE U.S., now extremely common in most agricultural and urban areas in all of the lower 48 states.

Spread Amount
Collared doves have explosively expanded their range through most of the lower 48 and into Canada and Mexico. At southern latitudes, collared doves have been recorded rearing up to six clutches of chicks in one year.

Notes

Ecological
Considered sly and aggressive (especially when nesting) competitors, can engage in fierce fights. Eurasian Collared doves may be competitively displacing another native bird species and outcompeting them for food and nesting sites.
4
Agricultural
Legal protection was removed in Britain because it is known to damage crops. It also can cause damage in livestock facilities due direct consumption of livestock feedstuffs and the spread of Coccidia to livestock.
3
Infrastructure
Minor infrastructure damage to due to nest placement and deification when populations are dense.
1
Cultural
When present and roosting in large numbers, Eurasian Collared-Doves can become a significant noise nuisance, and they also produce large amounts of unsightly feces, which could spread disease to humans or pets.

Health
Can also carry the disease-causing parasite Trichomonas gallinae, which they may spread to native doves or to the native hawks that feed on them.

Popularly hunted in some areas of the United States. Hunting may reduce populations in rural areas but suburban populations will remain unaffected. In some places, like urban parks, Eurasian collared doves may be seen as an attractant for bird feeders.

Entry
A California non-game species, CDFG considers invasive, but spread throughout most of the suitable habitat in California.
0
Control
There is little hope of larger population control without substantial financial investment.
1
Outreach
For this non-game bird species, CDFG allows no daily bag limit or possession limit, but increase knowledge and outreach to increase the private access and overall cultural popularity to target this specie could be improved.
