Shorebirds are under threat from housing developments.

Shorebirds in Moreton Bay and across Australia are under threat from housing development that is being built on wetlands.

Biologists have said the competition in estuarine environments is becoming deadly for an increasing number of species as areas are transformed for projects such as airports and developments.

Richard Fuller, who is a Professor in conservation biology at the University of Queensland, said, "sometimes we can adjust development proposals so they don't affect these ecosystems.

"But development is systematically removing, bit by bit, the habitats these birds are using."
