The Yucatan wren (Campylorhynchus yucatanicus) is a species of bird in the family Troglodytidae. It is endemic to Mexico. Its natural habitat is subtropical or tropical dry shrubland, only found on the narrow coastal strip of the northern Yucatán Peninsula. One of the critical habitats of this species is the Petenes mangroves ecoregion of the Yucatan coast. It is threatened by habitat destruction.
The adult Yucatan wren is a small species about 18 centimetres (7 in) long. The face is whitish with a dark eye-stripe, and the crown is greyish brown. The upper parts are brown streaked with black and white, and the wings are brown and barred with dark brown and white. The tail is black barred with grey, with white tips to some of the outer feathers. The underparts are whitish with a dark cheek stripe and blackish spotting and barring. The juvenile is similar in appearance to the adult but with less contrast between the upper and underparts.
The Yucatan wren is endemic to a coastal strip of the Yucatan peninsula. It can be found in arid areas with scrub, large cacti, and pastureland edges. Its breeding range is even more restricted to a strip... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yucatán Wren sighting in Ría Lagartos Biosphere Reserve on a given day, based on 93 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 143rd most-seen of the 216 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and August
In those months about 10% of wildlife watchers report a Yucatán Wren in Ría Lagartos Biosphere Reserve on a given day, against under 5% in May–July and September–March, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Yucatán Wren sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Yucatán Wren sightings, Ría Lagartos Biosphere Reserve ranks 2nd at under 5%. The best odds are in Celestún Biosphere Reserve (Mexico, about 40%).
GBIF citizen-science records
It is estimated from how often the Yucatán Wren is recorded against all the birds logged in Ría Lagartos Biosphere Reserve (93 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.
