Methods whereby candidate coyote repellents and attractants can be evaluated are described. Repellents were tested by conditioning wild-caught captive coyotes to feed upon tethered domestic rabbits. Coyotes were then offered treated and untreated rab

Research to assess the use of diphacinone as a predacide was divided into three primary phases: (1) acute oral toxicity tests with laboratory (captive) and free-ranging coyotes (Canis latrans); (2) residue analysis in tissues from coyotes killed by d

Crown-rump length, hind-foot length and weight of known-age coyote (Canis latrans) fetuses dated from estrus and metestrus onset were measured both fresh and after formalin fixation. Regression equations were established for predicting fetal age. All
