Little Spiderhunter

The little spiderhunter is a long-billed nectar-feeding bird of the sunbird family found in the moist forests of South and Southeast Asia. Unlike typical sunbirds, males and females are very similar in plumage, and the male has an all-black bill (Wikipedia, general species account).

It is usually seen in ones or twos and frequently gives a tzeck call, with a buzzy zick-zick call made regularly when disturbed or foraging; the song is a series of rapid chipping notes that can go on for long periods. It has gone locally extinct in Singapore's botanical garden (Wikipedia, general species account).
