Not far from Portland, near the western end of Victoria’s coast, you can find a nesting colony of Australasian Gannets on the mainland. All the others are on offshore islands. This one began in 1996 and is the extension of a large colony on the nearby Lawrence Rocks. Seabirds tend to return to their birthplace to mate and there was simply no more room at the inn.
In its first year the colony failed to get a single chick into the adult population. Foxes, feral cats and human disturbance seemed to be the problem so the colony was fenced off. I’ve heard it said that it’s now grown to about 3000 birds and is fairly successful. I doubt the true figure is that high but here’s what it looks like from the carpark. By my count that’s 257 birds but feel free to count for yourself.
An adult drops Into that crowded space with a beak full of seaweed. Building material for the new nest.
I suspect the cement is simply guano. All going well a big fluffy chick will come into being.
The parents will range up to 50km from the nest to bring back food for the youngster. They are spectacular plunge divers. It’s great entertainment when a squadron of gannets gets onto a school of fish.
