When not in the US, the species often winters in western Mexico.

Likely
About 40% of wildlife watchers report a Costa's Hummingbird sighting in Cabo Pulmo National Park on a given day, based on 88 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 100 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.
October
In that month about 70% of wildlife watchers report a Costa's Hummingbird in Cabo Pulmo National Park on a given day, against about 30% in March–June and September, the lowest months. July and August have too few records to rate.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Costa's Hummingbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 9
Of the 9 parks where we can rate Costa's Hummingbird sightings, Cabo Pulmo National Park ranks 2nd at about 40%. The best odds are in Bahía de Loreto National Park (Mexico, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Costa's Hummingbird is recorded against all the birds logged in Cabo Pulmo National Park (88 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.
