The yellowish pipit (Anthus chii) is a species of bird in the family Motacillidae, the wagtails and pipits. It is found in Panama and in every mainland South American country except Ecuador and Chile. The yellowish pipit was described in 1818 with the binomial Anthus chii. For much of the twentieth century and into the twenty-first it bore the binomial Anthus lutescens. A paper published in 2021 showed that by the principle of priority its original binomial was correct and taxonomic systems soon made the change.
What is now the Peruvian pipit (A. peruvianus) was previously treated as a third subspecies. It was separated based on a study published in 2018. The yellowish pipit is one of the smallest members of genus Anthus, and is unusually long-legged and short-tailed. It is 10.5 to 14 cm (4.1 to 5.5 in) long and weighs 13 to 18 g (0.46 to 0.63 oz). The sexes have the same plumage. In fresh plumage adults have a dark brown head with a very pale supercilium and a thin white eye-ring. Their upperparts are dark brown with buff... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yellowish Pipit sighting in El Impenetrable National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 215th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Yellowish Pipit in El Impenetrable National Park on a given day, against under 5% in January to October, the lowest months. That is one of El Impenetrable National Park's wettest months, with about 120 mm of rain against 25 mm in July. December has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellowish Pipit sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 7
Of the 7 parks where we can rate Yellowish Pipit sightings, El Impenetrable National Park ranks 3rd at under 5%. The best odds are in Iberá National Park (Argentina, about 20%) and Serra da Canastra National Park (Brazil, under 5%).
Same order: Passeriformes
The closest relatives of the Yellowish Pipit that you can see in El Impenetrable National Park (order Passeriformes, Perching Birds) are Brazilian Cardinal (about 80%), Blue-gray Saltator (about 80%) and Pearly-vented Tody-Tyrant (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellowish Pipit is recorded against all the birds logged in El Impenetrable National Park (6 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.
