What factors affect the range of hummingbirds?

Different species of hummingbirds show significant differences in range, which are mainly affected by geography, climate and ecological environment. Here are some specific examples:

Black-chipped northern hummingbird: Found primarily in the western part of the United States and Canada, it adapts to cooler climates and diverse terrain, including mountains, forests, and grasslands.

Red-throated Northern Hummingbird: Breeds primarily in eastern North America, but migrates south to Central America or the Caribbean during the winter in search of warmer climates and abundant food resources.

White-tailed sickle-billed hummingbird: Ranging from Costa Rica to Peru, it inhabits the tropical regions of Central and South America, adapting to warm and humid climates and dense forests.

Scaly-throated Hidden Hummingbird: Found mainly in eastern South America, preferring specific plant resources, such as the nectar of the scorpiontail plant.

Horned hummingbird: Found in Brazil, Bolivia and Suriname in South America, it inhabits mainly dry savanna and woodlands, avoiding humid forest environments.

Flashing Hummingbird: Ranges from Colombia to Peru, with different breeding seasons depending on the climatic conditions of different regions, reflecting its adaptability to environmental changes.

Brown-breasted hummingbird: Found in parts of Central and South America, its habitat includes a variety of environments from dry forests to riparian woodlands.

Green Hidden Hummingbird: Found mainly in Central and South America, from Panama and Costa Rica south to eastern Peru, northeastern Venezuela and the island of Trinidad, adapting to a variety of ecological environments.

Brown-tailed hummingbird: Found on riverbanks and woodlands, from the edge of wild forests to coffee plantations and banana plantations, it is often a pollinator of coffee and bananas.

Brown-Purple-eared Hummingbird: Found primarily in the rainforests of the mountainous region of the central United States, it is adapted to high humidity and abundant vegetation.

Green-crowned hummingbird: Found in the highlands from Costa Rica to western Ecuador in Central America, unlike most hummingbird species hovering over flowers, they inhabit plants while feeding.

Mount Ecuador hummingbird: lives at high altitudes in the Andes Mountains, feeds along the slopes of the mountains, adapts to the cold climate and thin air.
