Zeledon's antbird (Hafferia zeledoni) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Colombia, Costa Rica, Ecuador, Nicaragua, and Panama. Zeledon's antbird has two subspecies, the nominate Hafferia z. zeledoni and H. z. berlepschi. American ornithologist Robert Ridgway described them in 1909 in the same paper as separate species, Myrmeciza zeledoni and M. berlepschi. Both taxa were later treated as subspecies of Myrmeciza immaculata, which was at the time called the immaculate antbird. Beginning in 2012 the immaculate antbird was split into what are now the blue-lored antbird (H. immaculata with two subspecies) and Zeledon's antbird with its two subspecies. A molecular phylogenetic study published in 2013 found that genus Myrmeciza was polyphyletic. In the resulting rearrangement to create monophyletic genera, Zeledon's antbird was moved to the newly erected genus Hafferia.
The species' English name and specific epithet commemorate the Costa Rican ornithologist José Cástulo Zeledón. Zeledon's antbird is 17 to 20 cm (6.7 to 7.9 in) long and weighs about 40 to 56 g (1.4... Wikipedia →

Rare
Under 5% of wildlife watchers report a Zeledon's Antbird sighting in Monteverde Cloud Forest Reserve on a given day, based on 621 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 135th most-seen of the 412 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.
June–August, October and December–January
In those months about 10% of wildlife watchers report a Zeledon's Antbird in Monteverde Cloud Forest Reserve on a given day, against under 5% in February–May, September and November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Zeledon's Antbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 11
Of the 11 parks where we can rate Zeledon's Antbird sightings, Monteverde Cloud Forest Reserve ranks 4th at under 5%. The best odds are in Darién National Park (Panama, about 10%), Tapantí-Macizo de la Muerte National Park (Costa Rica, about 10%) and Farallones de Cali National Natural Park (Colombia, about 10%).
Same family: Thamnophilidae
The closest relatives of the Zeledon's Antbird that you can see in Monteverde Cloud Forest Reserve (family Thamnophilidae, Typical Antbirds) are Plain Antvireo (about 10%) and Slaty Antwren (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Zeledon's Antbird is recorded against all the birds logged in Monteverde Cloud Forest Reserve (621 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.
