“Laughing in the face of danger doesn’t negate the fear, it simply enables you to smile at it.”
― Richelle E. Goodrich
I really wanted to title this “Get off my land!” but, “Alarm!” won out.
This is very typical behaviour for male red winged blackbirds, especially during nesting season. They are very protective of their shoreline nests. The female will also join in with rapid chirps and tail fanning, but the male squeals out loud alarms and puffs itself up when agitated. I’ve seen some dive bomb and peck at people who have inadvertently or deliberately come too close to the nest . This guy was happy to sit on his perch and vocalize his dissatisfaction without getting too aggressive.
