Adult male: Forehead, crown, and nape iridescent metallic green. Mantle, back, and rump deep crimson. Uppertail-coverts iridescent metallic blue. Wings dark brown. Tail black with metallic blue sheen, central tail feathers elongated and pointed. Underparts crimson, becoming olive-yellow on belly and vent.

Ciri pembeda

Males are unmistakable with their brilliant crimson and metallic green. Females are more subtly colored but can be identified by their small size, slender decurved bill, and active feeding behavior. The elongated central tail feathers of the male are a key feature.

Penampilan muda

Juveniles resemble adult females, but are generally duller and more uniformly olive-green, often with a yellowish wash on the underparts. Young males gradually acquire patches of crimson and iridescent green as they mature.

Perubahan musiman

No significant seasonal plumage changes. Breeding and non-breeding plumages are essentially the same for both sexes.

Dimorfisme seksual

Highly sexually dimorphic. Males are much more brightly colored with iridescent crimson and metallic green, and possess elongated central tail feathers. Females are duller, predominantly olive-green and yellowish, lacking the bright iridescence and elongated tail feathers.

Cara identifikasi

1. 1

   Male Plumage

   Look for the striking combination of iridescent metallic green on the crown/nape and deep crimson on the back and underparts. The elongated central tail feathers are diagnostic.

2. 2

   Female Plumage

   Observe the overall olive-green upperparts and dull yellowish-olive underparts. Note the lack of bright colors and elongated tail feathers. The slender, decurved bill is key.

3. 3

   Bill Shape

   Both sexes possess a long, thin, and distinctly decurved black bill, perfectly adapted for nectar feeding.

4. 4

   Behavior

   Watch for their active, darting movements, often hovering briefly at flowers. They are constantly on the move.

5. 5

   Vocalizations

   Listen for their high-pitched, rapid 'chip-chip-chip' songs and sharp 'chip' calls.

Primarily feeds on nectar, hovering or perching to probe flowers with its long bill and tubular tongue. Also gleans small insects and spiders from foliage and bark, and occasionally catches insects in flight. They are important pollinators for many plant species.

Perilaku sosial

Typically seen singly or in pairs. May gather in small groups at abundant food sources. Generally not highly social outside of breeding pairs.

Pola terbang

Rapid, direct, and often darting flight, characterized by quick wing beats. They can hover briefly in front of flowers.

Pola migrasi

Resident throughout its range, with no significant migratory movements. Local movements may occur in response to flowering seasons.

Teritorialitas

Males can be territorial, especially during the breeding season, defending feeding territories and nesting sites from rivals.

Reproduksi

Varies geographically, generally March to August in most parts of its range, but can occur year-round in some tropical areas.

Kebiasaan bersarang

The female builds a small, purse-shaped or pear-shaped nest suspended from a branch or vine, often in a sheltered location. It is constructed from fine grass, plant fibers, cobwebs, and lichen, lined with soft materials like feathers or plant down. The entrance is typically on the side.

Jumlah telur

1-3 eggs, most commonly 2.

Deskripsi telur

Typically 2 eggs, sometimes 1 or 3. Eggs are whitish or pale greenish-blue, often speckled or blotched with reddish-brown or purplish-grey, particularly at the broader end.

Approximately 13-14 days, primarily by the female.

Masa terbang

Chicks fledge around 14-18 days after hatching.

Perawatan orang tua

Primarily the female incubates and broods. Both parents feed the nestlings, bringing them insects and spiders.

Di mana ditemukan

Tips lapangan

1. Look for flowering plants. Focus your search on areas with abundant flowers, as they are primary nectar feeders. They are often attracted to red or orange flowers.
2. Listen for calls. Their high-pitched calls can often betray their presence before you see them, especially when they are hidden in dense foliage.
3. Observe active feeding. Watch for small, fast-moving birds hovering or perching at flowers, probing with their long bills.
4. Be patient and still. Sunbirds are often quite bold but can be skittish. Remaining still and observing quietly will increase your chances of a good view.
