Introduction
The White-booted Racket-tail, Ocreatus underwoodii, is a small Andean hummingbird named for the white feather tufts around its legs and the male’s unusual racket-tipped tail. It inhabits humid montane forests, cloud forests and forest edges from northern Venezuela through Colombia to western Ecuador.
Physical Description
The White-booted Racket-tail is a small hummingbird with predominantly metallic green plumage. Its most distinctive features are the fluffy white leg tufts, or “boots”, and the male’s elongated outer tail feathers. Each of these feathers has a partly bare shaft ending in a flattened, racket-like flag.
Males generally show a strongly iridescent green throat and breast, with darker lower plumage and conspicuous tail streamers. Females are shorter-tailed and lack the male’s elongated rackets. They have green upperparts and mostly white underparts marked with green spotting, although the extent of spotting varies between geographic forms. Young birds and females can therefore appear much less ornate than adult males.
Published field-guide measurements vary with sex and the treatment of the tail. Males are approximately 11–15 cm long, including the elongated tail feathers, while females are about 8–9 cm long. The body itself is considerably shorter than the male’s total length suggests.
Range and Habitat
The species occurs in northern Venezuela, the Andes of Colombia and the western slope of the Andes in Ecuador. It is not a migratory species in the usual sense, although local movements may follow flowering plants and changing food availability. Older accounts included populations now generally treated as Peruvian Racket-tail, Ocreatus peruanus, so records from eastern Ecuador and Peru should be checked against the taxonomy being used.
White-booted Racket-tails occupy humid montane and subtropical forest, cloud-forest edges, forest clearings, shrubby slopes and flowering gardens. They are usually found from roughly 1,200 to 3,000 metres, although the precise elevation varies across the range and among subspecies. The species depends on a network of flowering plants, forest cover and suitable perches in landscapes that may include both intact forest and well-managed rural habitats.
Where to See This Species
Las Cotingas Bird Reserve, Pichincha, Ecuador
Las Cotingas Bird Reserve near Mindo has a documented record of White-booted Racket-tail and provides suitable humid cloud-forest habitat with flowering plants and forest edges. The species is best sought during active morning periods, particularly around flowering shrubs and hummingbird viewing areas, although sightings are never guaranteed.
Nearby accommodation: Mindo is the practical base, with guest houses, hotels, birding lodges, cabins and other small-scale accommodation.
Finca Bosque de Niebla, Valle del Cauca, Colombia
Finca Bosque de Niebla near Cali has recorded White-booted Racket-tail and protects accessible mist-forest habitat on the western Andean slopes. Early visits to flowering areas, forest edges and quiet trails offer the best chance of detecting this fast-moving hummingbird.
Nearby accommodation: Cali is the main accommodation base, with hotels and guest houses, while rural lodges and farm stays are available in the surrounding hills.
Otún Quimbaya Fauna and Flora Sanctuary, Risaralda, Colombia
White-booted Racket-tail is documented from the Otún Quimbaya sanctuary, a protected area of humid sub-Andean forest in the western Andes. The sanctuary’s wet forest, clearings and flowering plants make it a realistic site for searching, particularly along established trails and around forest-edge habitat.
Nearby accommodation: Pereira is the principal gateway, with hotels, guest houses and organised day visits available for the sanctuary.
Behaviour and Diet
This hummingbird is highly agile and spends much of the day flying between flowers, perches and territorial boundaries. It feeds mainly on nectar from tubular and other nectar-rich flowers, using its long, slender bill and extensible tongue. Small insects and spiders are also taken, providing important protein, particularly during breeding and while young birds are developing.
Males may defend productive feeding areas from other hummingbirds and can be persistent in chasing intruders. Courtship includes rapid flight displays in which the male’s elongated tail feathers and racket-shaped flags are conspicuous. The species is generally seen singly, although several individuals may gather where flowering plants or feeders are concentrated.
The female builds a small cup-shaped nest from plant fibres and other fine materials, often camouflaging the exterior with moss or lichen. She lays two small white eggs, incubates them alone and feeds the nestlings with a mixture of regurgitated nectar and small arthropods. Breeding timing varies geographically and may be linked to local rainfall and flowering conditions.
Identification Tips
- Look for a small, metallic green hummingbird with conspicuous white feather tufts around the legs.
- Adult males have two exceptionally long outer tail feathers ending in flattened, racket-like flags.
- Females have a shorter, deeply forked tail without the male’s elongated rackets, white underparts with green spotting and reduced leg tufts.
- The species is usually encountered in humid Andean forest, forest edges, flowering clearings and mountain gardens.
- Do not assume that every “booted racket-tail” in eastern Ecuador or Peru is this species. Current taxonomies generally recognise Peruvian Racket-tail, Ocreatus peruanus, separately from White-booted Racket-tail.
- The white leg tufts help distinguish it from many other small green hummingbirds, while the male’s tail flags are diagnostic when seen clearly.
Conservation Status
The White-booted Racket-tail is currently treated as Least Concern under the available BirdLife International and IUCN assessment framework. It is not considered globally threatened, but habitat loss remains a concern, particularly where montane forest is cleared for agriculture, pasture, roads or settlement.
The species benefits from protecting cloud forest, maintaining connected forest edges and preserving flowering plants in rural landscapes. Private reserves, national protected areas, responsible ecotourism and sustainable land management can all help retain the habitat on which local populations depend. Because taxonomic treatments have changed, future assessments may treat the species and its former subspecies differently.
Frequently Asked Questions
Where does the White-booted Racket-tail live?
It occurs in the Andes of northern Venezuela, Colombia and western Ecuador, mainly in humid montane forest, cloud forest, forest edges and flowering clearings.
Why is it called the White-booted Racket-tail?
The name refers to two distinctive features: white feather tufts around the legs and the male’s elongated outer tail feathers, which end in flattened racket-like flags.
What does the White-booted Racket-tail eat?
It feeds mainly on nectar from flowering plants and also catches small insects and spiders. Arthropod prey is especially important during breeding and chick-rearing.
Are male and female White-booted Racket-tails different?
Yes. Males have much longer outer tail feathers with racket-shaped tips and usually more strongly iridescent throat plumage. Females have shorter, deeply forked tails and mostly white, green-spotted underparts.
Is the White-booted Racket-tail endangered?
It is currently assessed as Least Concern, although deforestation and other forms of habitat conversion can reduce local populations and fragment suitable Andean forest.
Can it be seen in Peru?
Records from Peru may refer to Peruvian Racket-tail, Ocreatus peruanus, which is generally treated as a separate species. Identification should therefore be checked against a current regional field guide or bird checklist.
