Why are there so many doves in Argentina?
The importance of year-round crops and the availability of grain in the southeast of the province of Cordoba, Argentina, are key factors for doves not to migrate and have a reproduction rate, unique in the world.
Agricultural Transformation and Its Impact on Dove Populations
Back in the 70’s, Cordoba was a purely cattle raising area, with a lot of native trees and little agriculture. Although the volume of doves was large, what accounted for the dove reproduction boom was the agricultural revolution with the arrival of soybean production. In those years, up to 80% of the fields were allowed to be cleared, so the farmers quickly transformed their lands into extensive crop fields, leaving 20% of the native forest intact. BINGO! That was exactly what the doves needed for their massive reproduction: grain to feed on all year round and roosts.
Crop Composition and Food Supply for Doves
Continuous Food Cycle Supporting Reproductiont
Another important point is that in May, when soybeans are harvested, wheat is planted immediately afterwards, grain that will be ready for the first doves born in September/October. The last three months of the year, the doves feed on wheat stubble and a native grass seed, which closes a complete cycle of annual food supply for the doves.
