Key field marks

• Size and Shape. Very small, compact bird with a short tail and a stout, pointed bill. Appears restless and constantly on the move.
• Male Plumage. Look for the striking combination of glossy dark blue-black on the head and back, contrasting sharply with a bright, vivid orange belly and yellow flanks. A white throat is also visible.
• Female Plumage. Females are olive-green above, with a duller yellowish-orange wash on the belly and a pale throat. While less striking than males, the yellowish-orange underparts are still a key identifier.
• Behavior. Observe its active foraging style, often hanging upside down to feed on berries and nectar. Its rapid, darting movements through the canopy are characteristic.
• Vocalizations. Listen for its high-pitched, thin 'tsip-tsip-tsip' calls or a rapid, buzzy trill. These calls are often the first indication of its presence.
