Lavender Waxbill: A Beautiful Red-tailed Kauai Finch
The Lavender Waxbill brings grace and vigor to Kauai’s bird population because this bird possesses unique qualities of charm. This bird is originally from Africa but now adorns Kauai’s already diverse bird inventory.
Its soft lavender-gray plumage, contrasted by a red tail, and its presence in the sky, with its delicate movements, make this small finch a visual delight.
In this article, I will discuss what it looks like, its habits, and exactly how it helps the Kauai ecosystem.
Key Takeaways
- Delicate Beauty and Ecosystem Impact: The Lavender bird contributes attractiveness and variety to the community of avifauna of Kauai, but at the same time, it raises issues regarding the role that invasive species play in the local environment.
- Resilience and Adaptation: The bird, however, has been able to cope with some challenges, such as habitat disruption, well enough to present a good account of itself both in the wild and in captivity.
Lavender Waxbill
Glaucestrilda caerulescens
This finch bird gets instant attention because of its small size, appreciative nature, and graceful look with delicate features. The plumage consists mainly of soft lavender-gray, while the tail is its striking mark of color.
This bird lives in Kauai’s tropical environment, offering bird lovers an opportunity to watch this beautiful invasive birds of Kauai species in the wild.
Physical Appearance
This finch is measured 4 inches long and has a white belly and dark eyes this add beauty in this elegant finch. The graceful movements and small size make it a delight to the perpetually moist landscapes of Kauai.
Its principal diet consists of seeds, and it has a very slender, conical beak that’s just right for cracking those seeds. Because of its streamlined body, it often wins bird enthusiasts’ admiration for a poised and refined look.
How did the Lavender Finch arrive on Kauai?
This lavender bird comes from sub-Saharan Africa, on the Hawaiian islands as an accidental introduction. During early 20th century some exotic bird collectors transport these birds to the region in order to bring new species into local aviaries.
This non-native species has spread in the lush environments of Kauai, joining the island’s bird population. But this introduced species tends to upset ecosystems, and this bird has managed to get well with Kauai’s native flora and fauna.
Impact on Kauai’s Ecosystem
Kauai’s ecosystem also got beauty and complexity with the introduction of the lavender bird. It is not as aggressive as some invasive species, but its presence does negatively affect the local environment.
This bird competes with other seed-eating birds for their food sources. But it does not present a major danger to Kauai’s native bird species.
Taxonomy
The lavender waxbill[1] is a member of the Estrildidae (small finch) family and includes many species that are conspicuous for their bright plumage. Estrilda caerulescens is its scientific name. Many species of Estrildidae are widespread throughout tropical and subtropical regions of the world.
This bird is distantly allied with other waxbills, finches, and estrildid species, which are well known for their unique appearance as well as social behavior. It has lavender-gray feathers and a red tail, something no other bird in its family has.
Identification and Behavior
The lavender finch is generally easy to distinguish and has a greyish-lavender-reddish color, with a very slim and slightly curved beak and a red tail. As with so many other members of the waxbill family and finches, it normally migrates in flocks and associates with other species when searching for food.
This bird is described as having very gentle, interacting behavior in small flocks and that is because it is incredibly flexible in terms of where it lives as it adapts to open Savannah grasslands, woodland, and even sub-tropical forests.
They are weaker calls and singing that harmonizes with the Kauai island sounds. As generally retiring, these birds do crazy cute stunts; however, they become very social with other bird species.
Natural Habitat
Native to open grasslands, savannas and shrublands, it has no shortage of food and nesting sites in its range. This bird has been adapted to the tropical landscape on Kauai, where it is found in gardens, forest edges, and seed-bearing fields.
Kauai’s warm, humid climate makes this a perfect place for this bird to thrive. This lavender bird, with its abundant food and ample shelter, has managed to nest on the island in small populations in places where human effort is low and the natural resources are ample.
Statistics
The bird is 4 inches long, with a wingspan of 5 to 6 inches, the waxbill bird is easily identifiable because It is light and agile bird, and it weighs 7–10 grams. This bird can live up to 5 to 8 years in the wild, depending on environmental conditions and availability of food.
This species lays small clutches of 3 – 5 eggs, and the incubation period is from 12 – 14 days. After about 3 weeks, the chicks leave the nest and stay with their parents for some more weeks before they fully learn to forage and navigate their new surroundings.
Hotspots for Lavender Finch
If you are interested in seeing the red-tailed waxbill, you can find hotspots around Kauai, where they are rather common to spot. The wetland and forested areas of Hanalei National Wildlife Refuge combine to support these birds as an excellent habitat.
The birds also turn up at the Kilauea Point National Wildlife Refuge as a hotspot for these birds in areas with dense vegetation and open fields. Bird watchers often spot them as they look prominent through the trees, and their red tails shine in the sunlight.
The Lifespan of Lavender Waxbill
In the wild, waxbills can live around 5 to 8 years, depending upon the availability of food and environmental conditions. With healthy food and care, these small finches can live 10 years or more in captivity.
Their adaptability and ability to live in a number of different conditions, combined with their long lifespan, make this small birds suited for any environment they inhabit. A lot to do for its longevity is proper diet, minimal stress and lack of predators.
Their life spans are shortened in the wild by the natural wear and tear of survival, and captive birds often live longer in safe environments and regular checkups.
Selecting the partner, Courtship, and Mating
Red tailed waxbill are well known for strong pair bond that often develops during an elaborate courtship display. As a result males will sometimes hop and flap their wings to impress the female.
These displays are soft, melodic songs are used to woo a mate and if female likes him, she’ll signal back, generally with tongue bobbing.
Successive of such displays is followed by mating, and the pair continues to be cooperative during the whole breeding season, promoting a harmonious family view.
Nesting Habits
They build their nests in dense shrubs or tall grasses to protect themselves from predators and outside elements, and these nests are made up of different substances like grass, leaves and feathers to pack it warm nest.
Their nests are dome-shaped with tiny entrances that give the nests a secure and secret entry point, the female lays a clutch of 3 to 5 eggs, and both parents incubate the eggs.
Incubation normally lasts for 12 to 14 days and during this time, the parents start to stay around the nest to protect the eggs and keep them warm.
Chick Development and Fledging
Chicks of this species hatch helpless and have to be nursed by parents and both parents feed young chicks for the first few weeks on a diet rich in insects and soft seeds, keeping the young growing properly.
New feathers begin to sprout, along with gaining strength day by day, and at the age of 3 weeks, the chicks begin to fledge and leave the nest to explore the world around them.
But after fledging, they are totally dependent on their parents for food for another couple of weeks while they develop their ability to forage on their own and fly independently.
Threats
The birds, are quite adaptable and unfortunately, face perils in the wild. An enormous challenge, habitat loss associated with human development is one of the primary means these birds lose suitable nesting sites and food sources.
They are also subject to predation by larger birds, mammals and invasive species, and a persistent threat to their numbers. Changes in climate patterns elsewhere have also altered food availability in some areas, especially during the breeding season when the birds have to raise their young successfully.
Preserving natural habitats and maintaining a balanced number of native and introduced species is necessary for the ongoing survival of the red-tailed waxbill in Kauai and elsewhere.
Things to Know
The important information about this lavender bird is as under:
- Size: The waxbill is a relatively small bird and it is different from other birds of similar size because of its bright red tail.
- Diet: Seeds are the main food of the birds, and mostly grass seeds. They also feed on small insects and add to their protein requirement, for instance, during a breeding season and may eat soft fruits or berries.
- Habitat: We see these waxbills in open country, scrub, and savannah habitats. They are living close to fields or woods, lightly wooded areas with many seeds and insects.
- Lifespan: These birds normally live 5 to 8 years in the natural environment but can live up to 10 years or more in captivity.
- Invasive or Not: These are invasive birds and are introduces in 20th century on Hawaiian islands.
