Undocumented migrants trekking on foot and packed into vehicles are heading north from the southern border in greater numbers. Some are dying along the way, and Border Patrol agents are frustrated.
Government agencies kill more than 68,000 coyotes a year to keep them from preying on livestock and big game. But scientists say tracking them might be a better solution.
A Utah state program that pays a bounty for dead coyotes brought in about 1,000 more carcasses last year, despite criticism after the shooting death of a well-known wolf mistaken for a coyote, according to a Division of Wildlife Resources report.
