Red-Winged Blackbird Attacks in Winnetka and Surrounding Areas

On most days, Teri Weber walks along Sheridan Road in Winnetka to see Lake Michigan between the homes. Recently, on the 400 block of Sheridan, she experienced a startling encounter when red-winged blackbirds dive-bombed her. ‘The first one came from behind, and then the second one came toward my face,’ she explained. ‘I ducked, waved my hat, and started screaming.’

Her social media post about the incident received fifty responses, with local residents sharing similar experiences. Nancy Davidson from Wilmette recounted being attacked twice by red-winged blackbirds during her regular exercise routine. ‘I was completely surprised as the bird came out of nowhere,’ she said. ‘It flew into my head, and I left immediately.’

According to JP McNamara, Marketing and Communications Manager for the Wilmette Park District, this behavior is typical during the early nesting season. Male red-winged blackbirds become territorial, protecting their nests from perceived threats. These birds are common in Illinois during spring and summer.

While the behavior can be startling, it is generally meant to deter predators rather than cause injury.

Bridget Kiernan from the Chicago Botanic Garden noted the increase in aggressive behaviors from these birds in recent weeks, mentioning it’s typical during this breeding season. ‘Red-winged blackbirds are good at what they do,’ she said. Their aggressive territorial defense has led to their success.

The birds nest near water bodies, and dive-bombing incidents increase in June after the chicks have hatched. By July, such actions decline as the breeding season concludes.

Leah Pietrusiak, a Chicago resident, experienced such an attack near the Humboldt Park Boat House. She shared her experience on social media, finding others with similar stories. Pietrusiak plans to stay cautious around nesting areas, particularly in summer.

Teri Weber believes local officials should take steps to prevent nests from forming in public areas before the birds lay eggs. Once the eggs are laid, the nests cannot be removed due to legal protections.

Kiernan suggests residents wear wide-brimmed hats and protect their heads and necks during nesting season when red-winged blackbirds are known to attack. Familiarizing oneself with the bird’s warning calls can also help anticipate entering nesting territories.

A recording of the bird’s sound is available through the National Park Service.
