The white-tailed shrike-tyrant (Agriornis albicauda) is a species of bird in the family Tyrannidae. It is found in Argentina, Bolivia, Chile, Ecuador, and Peru. The white-tailed shrike-tyrant has a complicated taxonomic history. It was formally described in 1863 as Dasycephala albicauda. Soon thereafter andicoloa was discovered to have been used for a subspecies of the grey-bellied shrike tyrant (A. micropterus) so by the principle of priority the new species was renamed A. pollens. That taxon and Dasycephala albicauda were combined in the early twentieth century and again by the principle of priority the species became the present Agriornis albicauda.
The white-tailed shrike-tyrant is 25 to 28 cm (9.8 to 11 in) long. The sexes have the same plumage. The two subspecies are practically indistinguishable though A. a. pollens may be slightly larger than the nominate. Adults have a dark gray-brown... Wikipedia →

Rare
Under 5% of wildlife watchers report an Agriornis andicola sighting in Lauca National Park on a given day, based on 37 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 92nd most-seen of the 112 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report an Agriornis andicola in Lauca National Park on a given day, against under 5% in January–June, August and October–November, the lowest months. That is one of Lauca National Park's driest months, with about 5 mm of rain against 150 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Agriornis andicola sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Lauca National Park, in our data
Lauca National Park is the only park on Wallace's Line with enough records to rate Agriornis andicola sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Agriornis andicola is recorded against all the birds logged in Lauca National Park (37 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
