Figure 1. A blue jay perched in a pin oak (Quercus palustris) growing on the farm lawn searching for male beetles about to land on the grass after the insects had detected a pheromone-releasing female near the spot. Jays will fly up to 35 meters from their perches in trees to capture beetles that have slowed their flight and dropped close to or onto the lawn near a calling female.
