Lakshmi Ravishankar’s video clip of Scaly-breasted Munias (Lonchura punctulata) feeding on a green mat of growth along a stream was documented in Pune, India (below). An earlier post shows similar feeding in a drain in Perak, Malaysia.

Commonly known as Water Silk, Mermaid’s Tresses and Blanket Weed LINK, Spirogyra is a group of filamentous green algae that grow in clean freshwater where they develops into a slimy green mass floating on the water surface (top).

Under the microscope it can be easily identified by the spiral arrangements of the chloroplasts (above, below).
