A new study from the University of Melbourne has found that planting native shrubs and providing a water source are the most effective ways to attract blackbirds to urban gardens. The research, published in the journal Urban Ecosystems, surveyed 50 gardens across Melbourne and tracked bird visits over two years.
Key Findings from the Study
Gardens with at least three native shrub species saw a 40% increase in blackbird visits compared to those with exotic plants. Water features, such as birdbaths or small ponds, also boosted visitation by 25%. Lead author Dr. Emily Chen said: "Blackbirds are highly responsive to native vegetation, which provides both food and shelter."
Why Native Plants Matter
Native shrubs like lilly pilly and grevillea produce berries and insects that blackbirds rely on. In contrast, exotic plants often lack these resources. The study also noted that gardens with a mix of ground cover and tall trees attracted more blackbirds, as they prefer layered habitats.
Practical Tips for Gardeners
To create a blackbird-friendly garden, the researchers recommend planting a variety of native species, avoiding pesticides, and maintaining a clean water source. Dr. Chen added: "Even small changes can make a big difference for urban wildlife." The study highlights the importance of individual gardens in supporting bird populations amid urban expansion.
