BOISE, Idaho (AP) — Wildlife officials are investigating after residents reported a large number of dead songbirds in Kuna, a city about 18 miles southwest of Boise.

The Idaho Statesman reports that the dead birds show no signs of physical injury and were not sickened by plague. Idaho Department of Fish and Game regional conservation educator Evin Oneale says the cause of death appears to be a specific type of pathogen that has yet to be determined.

Oneale says no similar dead bird sightings have been reported in other parts of the Treasure Valley. He advises residents who see numerous dead birds to report them to Fish and Game immediately.
