Birds Build Nests With Our Trash!
2 Oct
Summary
- Australian birds collect rubbish like cigarette butts and plastic for nests.
- Human-made materials in nests rose from 4% in 1832 to 30% in 2018.
- Project 'Peckable Architecture' provides natural nesting materials in Melbourne.
As spring arrives in Australia, a concerning trend sees native birds incorporating human rubbish into their nests. A global study revealed litter, including cigarette butts and plastic, found in nests of 176 bird species, posing dangers like choking and poisoning. This issue is compounded by an existing biodiversity crisis and the recent detection of bird flu in Australia.
Historically, the use of human-made materials in Australian bird nests has dramatically increased. Between 1832 and 2018, this figure rose from 4% to 30%, with plastics being a major component. This resourcefulness, however, comes at a significant cost, with entanglement in materials like string and fishing wire a serious threat.
To combat this, Melbourne is piloting an initiative called 'Peckable Architecture.' As part of the Design x Nature exhibition, 100 bricks made from natural materials like bark and coconut fibre have been installed at Federation Square and the Royal Botanic Gardens. These bricks are designed to break down, offering birds a safer alternative.
Local residents can also assist by allowing natural materials like leaf litter and twigs to accumulate in their gardens and by providing safe, natural nesting materials. It's crucial to avoid long, stringy items that can entangle young birds. Picking up litter, especially hazardous items like cigarette butts and fishing line, also plays a vital role in protecting avian populations.
