Redwing

The Redwing (scientific name: Turdus iliacus) is a member of the thrush family (Turdidae) within the order Passeriformes. While often appreciated for its role in natural forest ecosystems, this bird species acts as a significant pest in commercial berry production and private orchards, causing substantial losses during the ripening season.

The Redwing poses a major threat to a wide range of fruit crops. Its primary targets include strawberries, raspberries, blackberries, currants, and various orchard fruits like cherries and serviceberries. Because these birds feed in flocks, they can quickly strip a small to medium-sized plantation of its ripe produce.

Understanding the biology of the Redwing is essential for effective pest management. While they consume insects during the nesting phase, their diet shifts significantly toward fruit as the summer progresses. Their ability to distinguish color makes them highly efficient at spotting ripe berries, ensuring that your most valuable, ready-to-harvest crops are the first to be targeted.

The damage caused is characterized by deep peck marks and partial consumption of the fruit. These damaged berries are not only unmarketable but also act as entry points for pathogens, leading to rapid rot and decay. This secondary damage can spread across the entire cluster, significantly reducing the overall harvest quality and shelf life.

To effectively manage the Redwing population and protect crops, agronomists recommend:

• Installing fine-mesh netting to physically exclude birds from crops.
• Deploying visual deterrents such as flash tape, reflective discs, and owl decoys.
• Utilizing acoustic deterrent systems that emit recorded distress calls.
• Implementing integrated pest management practices by monitoring bird activity during the peak ripening stages.
