“Saw 6 Java Sparrows (Lonchura oryzivora) feeding on the Commelina nudiflora (has many names, commonly known as the Common Spiderwort) (above, below). I am not entirely certain what part of the plant they are actually feeding on. They were addressing the growing tips and I suspect eating the seed capsule, but it could be the very young leaves. Note that seeds for this plant measure only 1mm but are in a capsule measuring 2x4mm. I did not see them eat the flowers.
“The plant has been well studied and is known to have antioxidant and antimicrobial activity, as well as good nutritional and mineral content (vitamin C, vitamin B3 & B2, Na, Ca, Mg). I have found the Java Sparrows astute at feeding on plants with good nutritional value.
“An edited video of some feeding is shown above.”
