Zimmer's tody-tyrant (Hemitriccus minimus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Brazil, Ecuador, and Peru. Zimmer's tody-tyrant has a complicated taxonomic history. It was originally described in 1925 as Snethlagea minima. By the mid-twentieth century it had been reclassified as a subspecies of Snethlage's tody-tyrant (then Snethlagea minor). Snethlagea was later merged into Hemitriccus. Early specimens were eventually reexamined and determined to be the same as "H. aenigma", what was at the time of its description thought to be a new species. The previous H. m. minimus was recognized as a species, merged with H. aenigma, and by the principle of priority became the present H. minimus.
The species' English name commemorates American ornithologist John Todd Zimmer. Zimmer's tody-tyrant is monotypic. Zimmer's tody-tyrant is about 10 cm (3.9 in) long and weighs 6 to 8 g (0.21 to 0.28 oz). The sexes have the same plumage. Adults have a dark brown-olive crown with even darker dusky streaks. They have buffy lores, an indistinct buffy eye-ring, and brown ear coverts. Their back and rump... Wikipedia →

Rare
Under 5% of wildlife watchers report a Zimmer's Tody-Tyrant sighting in Anavilhanas National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 182nd most-seen of the 291 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.
August
In that month about 20% of wildlife watchers report a Zimmer's Tody-Tyrant in Anavilhanas National Park on a given day, against under 5% in July, September and November–May, the lowest months. That is one of Anavilhanas National Park's driest months, with about 75 mm of rain against 340 mm in March.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Zimmer's Tody-Tyrant sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Anavilhanas National Park, in our data
Anavilhanas National Park is the only park on Wallace's Line with enough records to rate Zimmer's Tody-Tyrant sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Zimmer's Tody-Tyrant is recorded against all the birds logged in Anavilhanas National Park (15 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.
