Tanda lapangan kunci

• Blue Face. Look for the distinctive cobalt blue coloration on the face and crown, extending to the nape. This is a primary field mark.
• Tawny Breast. Observe the rich reddish-brown or tawny color on the breast and flanks, which contrasts sharply with the green upperparts and white belly.
• Green Body with Red Rump. Note the bright grass-green plumage on the back and wings, complemented by a crimson-red rump and uppertail coverts.
• Black Bill. The stout, conical black bill is a consistent feature in adults and helps distinguish it from some other parrotfinch species with paler bills.
• Habitat and Behavior. Search in dense montane forest undergrowth, especially near bamboo or grassy clearings. They are often seen in small, active flocks, clinging to grass stems to feed.
