GLEN ARBOR, Mich. (AP) — Recovery of some vulnerable species through restoration efforts has made comebacks more difficult for others in peril.

Once-endangered animals, including the iconic bald eagle, sometimes jeopardize rarer species such as the great cormorant by eating them or outcompeting them for food and living space.

Similar circumstances have turned up elsewhere, challenging wildlife experts who want all creatures to thrive in balanced, healthy environments.

Conflicts have involved revived U.S. species such as gray seals, birds of prey and even turkeys.

Wildlife managers around the country are working on creative solutions to the unanticipated consequences of species salvation.
