Scientists at the University of Wyoming are moving forward with research into coyote contraception. The goal is to control coyotes without killing them.
Researcher Marjie MacGregor says research has shown that coyotes without babies tend to leave livestock alone. So by controlling coyote reproduction, she hopes to be able to keep livestock safe.
MacGregor says the drug they’ve developed to sterilize male coyotes seems to work, at least in the short term. And they have not noticed any side effects.
