Eastern rosellas are active in the Reserve at present, flocking, chasing and squawking.
These rosellas, Platycercus eximius, are vividly coloured. The ones in Victoria are distinguished by green margins around their back black feathers- see the back feathers in the images below.
Their aerial antics include sweeping each other to the ground – see the image below – after which they just as quickly return to the trees.
Breeding season begins in August, through to February, and eastern rosella pairs mate for life. One clutch of eggs is produced in this time. The female selects the hollow and incubates the eggs whilst the male feeds her. They both then feed the young – which begin to fledge and fly, according to one article, at around four weeks.
A few of the eastern rosellas appeared to be searching for suitable nesting hollows, moving in an out of a couple of spouts- see below.
It also appeared that a couple of crimson rosellas were driving off the eastern rosellas – and this can happen, according to one source, with competition for good breeding hollows.
