Intrinsic and Extrinsic Factors Simultaneously Modulated the Use of Roadways by Golden Eagles During Winter. [PDF]

Ecol Evol
Golden eagles in the western United States are increasingly vulnerable to anthropogenic threats such as motor‐vehicle collisions, particularly during winter when live prey can be most limited and ungulate roadkill is more prevalent on the landscape. However, we lack an understanding of how other factors pertinent to eagles during winter (i.e., relative
