White ibises seem to be nesting already on Lake Wendouree’s islands. They are flying to and fro, carrying sticks in their beaks and making lots of noise. Will they really start nesting in the middle of winter?
It’s usual for the colony to start nesting at this time of the year. The reason for winter nesting is not clear. Milder weather would seem to suit the incubating parent and unfeathered chicks.
At this stage they seem mostly to be courting and nest-building. However, laying and incubation will soon take place. Eggs take around three weeks to hatch.
There will be increasing activity and noise as the colony progresses into spring and then early summer, after which the colony disperses and ibises become scarce for a few months.
