Bird Fact Friday — The Owls of Chile

Adapted from pages 142-143 of Birds of Chile:

The Magellanic (Lesser) Horned Owl is a very large owl with barred underparts; there are no similar species to it in Chile. They are widespread and common throughout virtually all of Chile, from the Patagonian steppe to city parks. They are mainly nocturnal, but in Patagonia can be seen in daytime, as on roadside fence posts. Their songs are two deep hoots, followed by, or run into, a quavering purr (hoo-hoo’urr-rr-rr). But, at a distance, only the hoo-hoo is audible. 

Meanwhile, the Rufous-legged Owl is mainly found in central or southern Chile, typically seen in old growth forests. They hunt at clearings and edges from low to mid-level perches, making roots and calls mainly at upper-to-mid levels. Its song is a varied series of pulsating barks run into low hoots, intensifying and then fading abruptly. These calls have a slightly maniacal quality; they’re a short series of resonant hoots (wuh-wuh wuh-wuh) followed by a rasping shriek. They are distinctive due to their rounded head, dark eyes, and voice.

The Peruvian (Pacific) Pygmy-Owl is the only pygmy-owl in northern Chile. These owls live on oasis valleys and farmland, in villages, and usually with some taller trees. They hunt from perches, low to high, including roadside wires, but are often mobbed noisily by smaller birds. They fly fast and are slightly undulating. Their song is a rapid tooting noise, almost too fast to whistle, with 10 notes/1.6-2.2 seconds (huihuihui). Their call is a high, chipping twitter. Their plumage is gray to brown overall.

Finally, the Austral Pygmy-Owl is native to central and southern Chile, commonly seen in the Tierra del Fuego, but some withdraw to the north and downslope in winter. These birds live in the woodland and forest, but can be seen in town parks, farmland, and semi-open country (at least in winter). Behaviorally, they are very similar to the Peruvian Pygmy-Owl. Their songs are fairly rapid, ringing toots, easily whistled at 10 notes/2.4-2.8 seconds, often with occasional changes in pitch and tempo (whih’whih’whih…). Their calls are high, chipping twitters. Their plumage is typically brown to rusty brown.
