Ever since my neighbour moved house, his lawn become overgrown somewhat. So regularly I had Scaly-breasted Munias (Lonchura punctulata) to observe as they visited once or twice daily to feast on the carpet grass (Axonopus compressus).
These birds arrived in a group of about half a dozen adults and juveniles. They spent up to half an hour feeding. Using the thin stems of the grass and other herbaceous weeds as support, they reached out to the fruiting stalks of the grass nearby with their bills to take in a few seeds at a time.
Note: In grasses the fruits are one-seeded, thus the seeds are actually fruits.
