The Ruby-throated Hummingbird is the only species of hummingbird that breeds in eastern North America. This small bird is particularly notable for the male's vibrant ruby-red throat, which contrasts sharply with his white underparts and emerald green back. Females lack the ruby throat and sport a more muted green and white coloring.
Ruby-throated Hummingbirds are migratory, spending the winter in Central America, southern Florida, and the Caribbean, and returning to North America in the spring to breed. Their migration includes a non-stop, 500-mile flight over the Gulf of Mexico, a remarkable feat given their tiny size.
These birds are primarily found in deciduous and pine forests as well as in gardens and at feeders where they feed on nectar. The availability of food sources heavily influences their habitat choice. In addition to nectar, they consume insects and spiders, crucial for protein intake especially during the breeding season.
Their agility in flight is astounding; they can hover in mid-air, fly backwards, and even upside down, a skill set that supports their nectar feeding.
