The Mexican sheartail (Doricha eliza) is a species of hummingbird in the family Trochilidae. It is endemic to Mexico. This is a tiny bird, weighing only 2.4 to 2.6 g (0.085 to 0.092 oz). 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 →

Likely
About 40% of wildlife watchers report a Mexican Sheartail sighting in Celestún Biosphere Reserve on a given day, based on 755 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 33rd most-seen of the 297 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May and June
In those months about 60% of wildlife watchers report a Mexican Sheartail in Celestún Biosphere Reserve on a given day, against about 30% in February–March and November–December, the lowest months. Those are among Celestún Biosphere Reserve's wettest months, with about 100 mm of rain a month against 10 mm in February.
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.
Yes
Of the 2 parks where we can rate Mexican Sheartail sightings, Celestún Biosphere Reserve has the highest daily chance: about 40%. Next come Ría Lagartos Biosphere Reserve (Mexico, about 30%).
GBIF citizen-science records
It is estimated from how often the Mexican Sheartail is recorded against all the birds logged in Celestún Biosphere Reserve (755 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.
