New lakeside home for native birdlife
EASTERN Park has been recognised for a very long time as an important place for native birds.
Although the old pines and gums growing there are not indigenous species, they have become extremely important habitat for many birds.
The botanic gardens are also significant, not just for the magnificent plant collection but for the birds that use them.
It is here that you may find the elusive pink robin in winter, while in spring sparrowhawks and hobbies (small falcons) nest in the pines.
Now there is a new attraction for birds. The small lake formed to retain runoff from the park has become home to another group of birds.
It is the result of careful planning by City of Greater Geelong staff and they deserve congratulations for the success of the project.
Local bird observer David Tytherleigh has watched at least one pair of Australasian grebes raising their young in nests built among the dense vegetation that fringes the open water, and a recent visit revealed many black ducks, grey and chestnut teal using the lake.
One concern that has been raised is that of dogs being taken there to swim. While there is no doubt that dogs appear to enjoy a swim, and it is great exercise for them, a conflict of interests seems inevitable if this continues.
Grebes build floating nests of aquatic vegetation anchored to emergent plants, and the four or five eggs that the birds lay are covered with waterweed when the parents are away from the nest.
The vegetation probably provides some warmth, but it may be used more to hide them from predators.
The fluffy young leave the nest almost as soon as they hatch, and will often hitch a ride on their parents’ back.
Grebes have sharply-pointed beaks, and dive underwater for tadpoles and small fish.
The adults are dark brown with a chestnut stripe at the back of the head, a pale yellow throat, and vivid golden eyes.
