Black-fronted Ground-tyrant
The Black-fronted Ground-tyrant is a small, pale gray flycatcher with a distinctive black forehead and crown contrasting against its otherwise plain gray-white body. It inhabits high-altitude rocky slopes, barren grasslands, and puna habitat in the Andes from Bolivia to northwestern Argentina, typically above 3,500 meters. It forages on the ground, running actively to catch insects and small invertebrates.
