The weather turned a bit cooler here lately, with overnight temperatures nearing 0 degrees Fahrenheit. This prompted all wolves to increase their appetite. A deer was fed to the Retired Pack on Thursday night, but by the end of the day Friday, there wasn't much left. The same is true for wild wolf kills. The USGS biologist has been reporting kill sites observed from the plane, and sees nearly 100% consumption within a day of the kill. In this week's photo, Lakota is breaking open deer bones to get at the rich bone marrow, high in fat and critical to the wolves diet on a cold day.
