Bee Hummingbird Identification Guide

Key Field Marks

• Size & shape: The smallest bird species on Earth, measuring only about 5-6 cm and weighing around 2 grams - smaller than many insects. Compact, round-bodied, with a short, straight, needle-like bill proportionally shorter than most hummingbirds.
• Plumage (breeding male): Iridescent fiery rose-pink to reddish head, throat, and elongated throat feathers (gorget) that can look dark or blackish in poor light and flare into brilliant color in direct sun; upperparts glossy blue-green.
• Plumage (female and non-breeding male): Green above, whitish-grey below, with white tips to the outer tail feathers; lacks the pink gorget, making it much less conspicuous and easily overlooked as an insect.
• Bill: Short and straight relative to body size, adapted for probing small tubular flowers.
• Behavior: Extremely fast wingbeats (among the fastest of any hummingbird), producing a distinct buzzing hum; hovers persistently at flowers and can appear almost stationary in mid-air; highly pugnacious and will chase off much larger birds from feeding territories.

Similar Species

• Other Cuban hummingbirds (e.g., Cuban Emerald): Noticeably larger with proportionally longer bills and no pink gorget on males; size alone is the best separator once a direct comparison is possible.
• Large insects (bees, sphinx moths): At a glance the Bee Hummingbird can be mistaken for a large bee or moth due to its size and hum; look for the bill, feet, and hovering/darting flight typical of a bird rather than an insect's more erratic flight.
• Female vs. male: Females lack any pink coloration and are best told from other small green hummingbirds by range (Cuba only) and their tiny overall size.

Where & When to See

• Habitat: Found in forest edges, woodland clearings, swampy scrub, and gardens with flowering plants; favors areas with abundant small flowers for nectar.
• Range: Endemic to Cuba and the nearby Isla de la Juventud - it occurs nowhere else in the world.
• Season: Resident year-round; breeding activity and the male's fully developed, brightest gorget are most likely to be seen in the dry season (roughly November through June).
• Best viewing tips: Look near flowering shrubs and vines, especially in botanical gardens or reserves such as Zapata Swamp; patience is needed as the bird's tiny size and fast flight make it easy to miss.

Voice

• Gives thin, high-pitched squeaky and chippering notes, often delivered in a rapid series while perched or displaying.
• The wingbeat itself produces an audible buzzing hum, which is often the first clue to the bird's presence before it is visually located.
• Males may perform display flights with accompanying vocalizations near flowering territories during the breeding season.
