The Purple-throated Carib Hummingbird (Eulampis jugularis) is a beautiful and unique hummingbird species found in the Caribbean region. With its glittering purple throat and dark, iridescent plumage, this hummingbird stands out among its relatives.
Description and Characteristics
The purple-throated carib hummingbird averages about 3.5 inches in length and weighs roughly 2-3 grams. As its name suggests, the adult male has a brilliant gorget (throat) that appears black in some lights but shimmers with vivid purple, violet, and green when hit by sunlight. The male’s head and upperparts are a dark, shining green while the underside is grayish white. Females lack the stunning purple gorget and are overall duller than the males, with a pale throat and whitish tips on the tail feathers.
Both sexes of purple-throated carib hummingbirds have fairly long, slender bills adapted for accessing nectar from flowers. Their wings beat incredibly fast, allowing them to hover in place or fly backwards, upside down, and in all directions. This agile flight gives them an advantage when feeding on nectar from specialized flowers and evading predators.
Native Habitat and Range
The purple-throated carib hummingbird is endemic to the Caribbean islands. Its range includes the Bahamas, Turks and Caicos, Cuba, Jamaica, Hispaniola, Puerto Rico, and the Lesser Antilles. It occupies a wide variety of habitats on these islands including orchards, forests, palm groves, parks, and gardens.
This species tends to prefer lower mountain slopes and valleys but can be found up to elevations of 5,000 feet in some areas. It is comfortable in tropical, subtropical, and desert climates across its Caribbean territory. The purple-throated carib hummingbird may be found in both pristine and degraded forest habitats as long as there are sufficient flowers available for feeding.
Diet and Feeding
Like all hummingbirds, the purple-throated carib meets its high energy needs by feeding on floral nectar and small insects or spiders. Its long, specialized tongue allows it to dart in and out of flowers, lapping up nectar. Some favorite nectar sources include hibiscus, heliconia, aloe, coral bean, and century plants.
While nectar provides the majority of its diet, the purple-throated carib hummingbird will also hunt small arthropods for essential proteins. It may glean insects from leaves and branches or snatch them out of the air during its acrobatic flight maneuvers. Common prey includes flies, mosquitoes, spiders, ants, and aphids.
Reproduction and Life Cycle
The breeding season for purple-throated carib hummingbirds varies across its range but typically aligns with peak flower availability. On most islands, breeding takes place between March and June. To attract females, males perform elaborate courtship displays, flying in loops and dives while making buzzing sounds with their tail feathers.
Once paired, the female builds a tiny cup-shaped nest out of plant down, spider webs, and lichens, attached to a thin branch or tree fern. She lays two pea-sized white eggs and incubates them alone for 14 to 19 days. The hatchlings are naked, blind, and helpless but grow quickly on a diet of regurgitated nectar and insects provided by the female. They leave the nest at about 3 weeks old but remain dependent on the female for another couple weeks.
Threats and Conservation Status
While still relatively common across most of its range, the purple-throated carib hummingbird faces some concerning threats. Habitat loss from deforestation and urbanization destroys nesting sites and nectar plant sources. Pesticide use can contaminate its food supply and lead to illness or mortality. Competition with invasive honeybees may limit access to flowers and nesting materials. Some illegal trapping for the pet trade still occurs in parts of its range.
The purple-throated carib hummingbird has a conservation status of Least Concern according to the IUCN Red List. However, some specific subpopulations are declining or endangered. Continued protection of tropical forests and flowering plants will be important for the long-term survival of this gorgeous Caribbean hummingbird. Sustainable agricultural practices, responsible eco-tourism, and public education can all contribute to its conservation.
Unique Adaptations
The purple-throated carib hummingbird has some remarkable anatomical and behavioral adaptations that allow it to thrive in the Caribbean. Here are a few of its most fascinating traits:
– Specialized tongue – Their long, forked tongues have tubes along the edges that suck up nectar. Splits at the tip grab insects.
– Precision flying – They can fly forwards, backwards, upside down, and hover in place, even in strong winds. This allows precise flowering feeding and aerial insect hunting.
– High metabolism – Very high metabolic rates (about 10x higher than an elephant’s!) provide the energy needed to power extreme activity levels. Heart rates reach up to 1,200 bpm.
– Torpor – To conserve energy overnight, they can lower their body temperature and enter a torpid state similar to hibernation. Their heartrate drops to 50-180 bpm and breathing slows.
– Eagle vision – Excellent eyesight enables them to spot food sources from afar. They see ultraviolet light, allowing them to detect nectar guides on flowers.
– Aggressive displays – Males perform dramatic dive displays to chase off competitors and impress females. Rapid dives create loud buzzing or popping sounds.
– Heat dissipation – They dissipate excess body heat through respiratory evaporation and by aligning their body feathers to increase airflow.
– Island adaptability – Highly adaptable to various island habitats and conditions. Able to utilize both pristine and degraded floral habitats.
By combining specialized adaptations with incredible agility and intelligence, the purple-throated carib hummingbird is a true master of life in the Caribbean. Their unique traits allow them to survive and thrive on islands throughout the region. Careful conservation measures will ensure the continued success of these marvelous hummingbirds.
Cultural Significance
The vibrant purple-throated carib hummingbird is featured in local folklore and artistic traditions across the Caribbean. People have long admired its flashy plumage, speedy flight, and energetic personality. Here are some of the notable ways this bird appears in regional culture:
– Numerous Caribbean legends center on hummingbirds. They are cast as messengers between humans and gods, as magic spirits, and as symbols of life’s fleeting joys.
