Ruby-throated hummingbird

Archilochus colubris

Also calledColibrí garganta de rubí (Spanish) · Colibri à gorge rubis (French) · Huitzilin (Nahuatl, hummingbird)

The only hummingbird that breeds widely in eastern North America. Weighing about 3 g, many cross the Gulf of Mexico nonstop, roughly 800 km, each spring and autumn.

The ruby-throated hummingbird 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. Wikipedia
