Experimental bricks break down naturally

The installation includes bark, casuarina needles, fine twigs, coconut fiber and moss. An organic gelatin binder holds these components together until birds collect them. The bricks are designed to disintegrate over time so animals can use the loose materials.

Sites face littering risks

A 2023 global study found trash in nests of 176 different bird species. Common culprits include cigarette butts, plastic bags and fishing nets that pose choking hazards. These materials endanger chicks through poisoning and entanglement while birds struggle with biodiversity issues.

Project launches during spring

The initiative targets the current nesting season when Australian birds build homes. Locations include Federation Square and the Royal Botanic Gardens in Melbourne. This approach offers alternatives to collecting human waste for nest construction.
