Java Sparrow – nesting material

posted in: Nests | 0

“Java Sparrows (Lonchura oryzivora) are doing well at some sites in the city especially around limestone caves where they nest, very high up. Over the years I have seen them collect material for nesting that includes:

1. Bamboo leaves – the favourite nesting material. The like the leaves of a fine bamboo; they pluck the growing end (above, below).

2. Wilga (Geijera parviflora) leaves – an Australian willow.

3. Buffalo/Hilo Grass (Paspalum conjugatum).

4. Also seen them using long trailing grasses.

5. A colleague has seen them stealing material from myna nests.

“On this occasion I saw two different sets of nesting birds build nests and I am fairly confident that both had helpers. One was a set of 3 adult birds that flew from their high nest together, down to collect material and then up again (saw the group do this twice). Another group working together was a set of 4 birds one of whom was a juvenile.”
