The California Department of Fish and Wildlife is examining the carcasses of several Canada geese and one duck found dead around Truxtun Lakes to determine what killed them and about a dozen other geese earlier this month. But it will take several weeks to get the necropsy results back from the state’s Wildlife Health Laboratory, according to Abby Gwinn, a biologist with CDFW who bagged several dead birds from Truxtun Lakes on Nov. 7. She wrote in an email that another live, but sick, goose was found last week and taken to a wildlife rehabilitation facility. It also died. “This one will be particularly valuable as we know it was sick prior to passing and we have a report of the symptoms,” Gwinn wrote in an email. “It is not uncommon to have an increase in bird diseases observed during migration when birds flock together, especially when habitat is limited like it is locally this year with the dry Kern River through town.”
