LAS VEGAS (AP) - Federal land managers will delay rounding up nearly 500 wild horses from a range in eastern Nevada until after the spring foaling season.

Advocates trying to block mustang roundups in Nevada said Monday their threat to sue stopped the U.S. Bureau of Land Management from carrying out February horse gathers in the Eagle Herd Management Area.

A BLM statement issued Saturday says there's not enough time to conduct the roundup before foaling season begins.

The bureau last week finished rounding up more than 1,900 horses from the Calico Mountains Complex north of Reno.

It's still considering what to do about some 50 horses that have moved outside the Eagle and Silver King herd management areas and are said to threaten the safety of motorists on U.S. 93 near Pioche.
