Wintering, however, is different. They gather in large flocks in Venezuela. Sometime in the late 20th century large agriculture projects plowed up much of wintering territory of this bird. The flocks of millions ate the crops. The farmers sprayed the crops & a good percentage of the dickcissels died. I think there were some efforts by bird preservation people to compensate the farmers for their losses, but I do not know how successful they were. Maybe the Zimbabweization of Venezuela has been favorable for the survivability of these birds.
