I found this male Brown-throated Sunbird foraging at Bunga Raya - Hibiscus flower, when I was eating nasi lemak at Mak Teh's stall (opposite the Raub Fire Station).
Menyedut madu bunga raya dengan menebuk pangkal bunga. Itu yang digelar "robbing nectar" - "merompak madu". Burung tidak terlibat dalam proses pendebungaan, kerana tidak menyedut madu dari depan kelopak bunga (petal) dan tidak kena pada pistil/stigma.

"Do they not look at the birds, held poised in the midst of (the air and) the sky?
Nothing holds them up but (the power of) Allah.
Verily in this are signs for those who believe". Surah An-Nahl (The Bee) 16:79
"Do they not see the birds above them, spreading out their wings and folding them in? None upholds them except the Most Beneficent (Allah). Verily, He is the All-Seer of everything". Surah Al-Mulk (67:19)
