The ruby-throated hummingbird (Archilochus colubris) is a species of hummingbird that generally spends the winter in Central America, Mexico, and Florida, and migrates to Canada and other parts of Eastern North America for the summer to breed. It is the most common hummingbird in eastern North America, having population estimates of about 35 million in 2021.
The ruby-throated hummingbird was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Trochilus colubris. Linnaeus based his description on the earlier account by Mark Catesby in his The Natural History of Carolina, Florida and the Bahama Islands that had been published in 1729 and that by George Edwards in his A Natural History of Uncommon Birds that had been published in 1743. The type locality is South Carolina. The specific epithet colubris is from the Spanish colibrí meaning "hummingbird". The ruby-throated hummingbird is now placed in the genus Archilochus that was introduced in 1854 by the German naturalist Ludwig Reichenbach. The species is monotypic: no subspecies are recognised.

Under 5% of wildlife watchers report a Ruby-throated Hummingbird sighting in Austin on a given day, based on 999 verified sightings from GBIF citizen-science data. It is the 110th most-seen of the 277 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.
September
In that month about 20% of wildlife watchers report a Ruby-throated Hummingbird in Austin on a given day, against under 5% in May–July and November–March, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Ruby-throated Hummingbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
22nd of 30
Of the 30 cities where we can rate Ruby-throated Hummingbird sightings, Austin ranks 22nd at under 5%. The best odds are in Orlando (United States, about 20%), Miami (United States, about 20%) and Houston (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Ruby-throated Hummingbird is recorded against all the birds logged in Austin (999 verified sightings), 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.
