The stub-tailed spadebill (Platyrinchus cancrominus) is a passerine bird in the Tyrannidae family. It is commonly found in tropical dry rainforests or tropical moist lowlands throughout Central America. First scientifically described in 1860, it was originally thought to be the same as Platyrinchus mystaceus but was later reclassified as a sympatric species. The stub-tailed spadebill may grow up to 9.5 cm (3.74 in) long and may weigh up to 12 g (0.42 oz). It has a white throat, yellow breast, and brown mantle and wings. The stub-tailed spadebill is most easily recognizable due to its stubby tail, broad bill, and its distinctive bird song. Some morphological differences like its greatly reduced crown differentiate it from other related species.
The stub-tailed spadebill is found in elevation ranges up to 500 m (1,640 ft) above sea level. As an omnivore it feeds on both arthropods such as spiders, beetles, and ants as well as low hanging berries and fruits in the lower strata of the rainforests. While many individuals may live in solitude, pairs that live together often nest in deep cone-shaped nests made with scavenged fibres. Stub-tailed spadebills also engage in mixed-species foraging flocks with other species commonly found in the same habitat. Engaging in this flocking behaviour is still not fully understood and is believed to be done for protection from predation. It is categorized as a species of least concern by the International Union for Conservation of Nature Wikipedia →

Possible
About 20% of wildlife watchers report a Stub-tailed Spadebill sighting in Calakmul Biosphere Reserve on a given day, based on 110 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 81st most-seen of the 271 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
February and July
In those months about 30% of wildlife watchers report a Stub-tailed Spadebill in Calakmul Biosphere Reserve on a given day, against about 10% in April–June and October–December, the lowest months. Those are among Calakmul Biosphere Reserve's driest months, with about 35 mm of rain a month against 130 mm in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Stub-tailed Spadebill 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 15
Of the 15 parks where we can rate Stub-tailed Spadebill sightings, Calakmul Biosphere Reserve ranks 3rd at about 20%. The best odds are in Tikal National Park (Guatemala, about 30%) and Cockscomb Basin Wildlife Sanctuary (Belize, about 20%).
Same family: Tyrannidae
The closest relatives of the Stub-tailed Spadebill that you can see in Calakmul Biosphere Reserve (family Tyrannidae, Tyrant Flycatchers) are Social Flycatcher (about 50%), Great Crested Flycatcher (about 40%) and Yellow-olive Flycatcher (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Stub-tailed Spadebill is recorded against all the birds logged in Calakmul Biosphere Reserve (110 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.
