Species Profile: Black-chinned Hummingbird

Common Name: Black-chinned Hummingbird
Scientific Name: Archilochus alexandri

Location: Widespread throughout Central Texas during the breeding season. Found in urban gardens, open woodlands, riparian areas, and desert scrub.

Mating Habits: Males perform elaborate diving displays in a U-shaped flight to attract females. After mating, females build tiny cup-shaped nests on branches, using spider silk, lichen, and plant down. Males do not assist in raising young.

Seasonal Habits / Migratory Patterns: Migratory. Arrives in Central Texas in early spring (March) to breed, and departs by late summer (August). Winters in Mexico. One of the most common hummingbirds in Texas during the warmer months.

Ecological Relevance: A key pollinator for many native plant species, including flowering vines, shrubs, and herbaceous plants. Their presence supports healthy plant reproduction and insect control.

Interesting Facts:

• The male has a distinctive black throat with an iridescent violet band visible in certain light.

• Can enter a state of torpor (temporary hibernation) on cold nights to conserve energy.

• Highly territorial, especially around feeders and flowering shrubs.

Native Plant Associations: Frequently feeds on flame acanthus, Turk’s cap, coral honeysuckle, penstemon, and native salvias. Also visits feeders for sugar water.

Conservation Note: Maintaining native flowering plants and avoiding pesticides helps support their breeding success. Place feeders out in early spring to support returning migrants.
