This behaviour might be cute in kaka, but you can see the route kea tread that leads to upsetting woolly ungulates. For scientific purposes I observed its actions, for face matching anti GCSB purposes the afflicted have been obfuscated. I am told they are trying to obtain oils from the hair (no, not the GCSB, the kaka). For a replay see 1003835
Wren's nesting in a box. It turns out that there were four chicks hidden under this plastic tray. Dramatic differences in the chicks within 5 days. Parents have become comfortable with me hanging around while they try to feed this brood. Final count was four. Day seven they fledged and left the nest. Last photo shows almost fledged birds allowing easier id.
