All Mexican sheartails have a long, curved and black bill, a dull green crown and bronzy-green nape and upper parts. Males and females are sexually dimorphic. The male, which is 9 to 10 centimetres (3.5 to 3.9 in) long including the tail, has a white line behind the eye and a pink-purple throat with a white band below. His underparts are dull green, being clearer on median belly and feathers covering his undertail. The male's tail is long and deeply forked, usually held closed in repose. His inner tail are feathers green, the rest being black with cinnamon inner margins. Females, at 8.5 to 9 cm (3.3 to 3.5 in), have a whitish face with a blackish stripe behind the eye. Her throat, chest and belly are whitish with cinnamon tinges on the sides. The female has a shorter forked tail, the outer feathers of which are reddish with a subterminal black band and white tips. Immatures are similar to females. Females are also far more commonly seen than males, typically outnumbering the latter... Wikipedia →

Possible
About 30% of wildlife watchers report a Mexican Sheartail sighting in Ría Lagartos Biosphere Reserve on a given day, based on 378 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 42nd most-seen of the 216 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
May, October and December–January
In those months about 40% of wildlife watchers report a Mexican Sheartail in Ría Lagartos Biosphere Reserve on a given day, against about 10% in March, the lowest month.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Mexican Sheartail sightings with a recorded time, and nearly all 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 Mexican Sheartail sightings, Ría Lagartos Biosphere Reserve ranks 2nd at about 30%. The best odds are in Celestún Biosphere Reserve (Mexico, about 40%).
GBIF citizen-science records
It is estimated from how often the Mexican Sheartail is recorded against all the birds logged in Ría Lagartos Biosphere Reserve (378 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.
