The Ochre-naped Ground-Tyrant is a large, lanky flycatcher that breeds in Chile and Argentina in open highland habitats.  An austral migrant, it migrates along the Andean chain north to Bolivia and Peru in the winter.  A distinctive species, this ground-tyrant is dark gray above and whitish below with a pale yellow cap.  The habits of Ochre-naped Ground-Tyrant are even more diagnostic than its appearance; the bird is strongly terrestrial and stands alert and upright when foraging, nervously fanning its tail.  In flight, this ground-tyrant shows a fast, low, swooping pattern accentuated by very long wings.

Identification

18·5–20 cm. Large and long-winged ground-tyrant. Has white forehead and supercilium, pale ochre crown patch; rest of crown and upperparts pale brownish-grey; wings duskier, narrowly edged white (in fresh plumage remiges broadly tipped white); tail black, outer rectrices edged white; throat and chest greyish-white, becoming white on lower belly and vent; iris dark brown; bill long, black; legs black. Sexes alike. Juvenile has crown patch faint or absent, buff edgings in wing. Race brevirostris is darker than nominate, slightly smaller bill and wings.

SUBSPECIES

Muscisaxicola flavinucha flavinucha Scientific name definitions

Distribution
N and C Chile (Antofagasta S to Colchagua) and W Argentina (Mendoza S to Santa Cruz).

SUBSPECIES

Muscisaxicola flavinucha brevirostris Scientific name definitions

Distribution
S Chile and S Argentina S to Tierra del Fuego.

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Stony slopes with little vegetation, near water; puna grassland and bogs. Mostly 2000–4500 m, also breeding at 500–1000 m S of N Chile; occasionally down to sea-level in S Chile, especially during inclement weather.

Movement

Migratory; spends austral winter (Mar–Sept) farther N, into Andes of W Bolivia and Peru.

Diet and Foraging

Insects. Mainly terrestrial, making short runs and hops, stopping suddenly and standing erect; less frequently, sallies from the ground or a rock; also searches in leaf litter and plants, flicking aside leaves for hidden insects.

Sounds and Vocal Behavior

Short high-pitched bursts, “tsee tee tsee tseet”.

Breeding

Oct–Feb; possibly double-brooded. During display, male flies high up with dangling legs, comes to a stall, then drops to ground. Nest an open cup made of grass, lined with feathers, placed in crack or cavity in rock, under stone, in rodent burrow, or directly on ground. Clutch 3 eggs, sometimes 2 or 4. No other information.
Not globally threatened. Uncommon to locally fairly common. One of the most abundant ground-tyrants in C Chile. Breeding range possibly slightly more extensive; scattered reports of potential breeders in Boliva (Oruro) and S Peru. Occurs e.g. in all national parks in Patagonian Andes; in non-breeding season also in Eduardo Avaroa National Park, in Bolivia.
