Wire-crested Thorntail
Appearance: The Wire-crested Thorntail is a small hummingbird measuring about 10-11 cm in length, including its tail. Males have a striking look with a metallic green body and an elongated, wire-like crest on the head. Their tail is long and forked, with thin outer feathers resembling wires, hence the name "thorntail." Females are less flamboyant, with a more subdued green plumage and a shorter tail without the wire-like extensions. They lack the crest seen in males.
Habitat: This species is found in subtropical or tropical moist lowland forests and montane forests. They are often observed at elevations ranging from 500 to 1,800 m above sea level.
Behavior: The Wire-crested Thorntail feeds on nectar, which it obtains from a variety of flowering plants. It also consumes small insects and spiders for protein. They are known for their agile flight, which allows them to hover in place while feeding. Males are often territorial, defending rich feeding areas from other hummingbirds.
Breeding: The breeding habits of the Wire-crested Thorntail are not extensively documented, but they are presumed to have similar nesting behaviors to other hummingbirds, building small cup-shaped nests. Females are responsible for incubating the eggs and caring for the young.
Conservation status: As of the latest assessments, the Wire-crested Thorntail is classified as Least Concern on the IUCN Red List.
