An advocacy group is protesting a National Park Service decision to kill deer in Washington's Rock Creek Park.
In Defense of Animals said it will hold a rally and vigil Friday and Saturday evenings.
The park service announced Wednesday that it would use sharpshooters to reduce the deer population in the park. It said the population needs to be cut to protect plant and animal habitat. The park has more than 70 deer per square mile, and the plan is to reduce that number to no more than 20 per square mile.
Sharpshooters are to work through early Saturday morning.
In Defense of Animals and several residents sued to try to stop the shootings, but a judge ruled in favor of the park service earlier this month.
