Vocalizations

Famous for its “chick-a-dee-dee-dee” call, which varies in intensity depending on perceived threats. Produces a clear, whistling “fee-bee” song, especially during mating season. Can mimic the sounds of other birds.

Feeding Habits

Omnivorous diet: Insects and spiders (caterpillars, beetles, aphids, and larvae). Seeds and berries. Sap from trees. Frequently visits bird feeders, preferring sunflower seeds, peanuts, and suet. Stores food in multiple locations (a behavior called caching) and remembers where it was hidden.

Social Structure

Forms small flocks in winter, sometimes mixed with other species like nuthatches and woodpeckers. Hierarchical dominance structure within flocks.

Cognitive Abilities

Remarkable memory: Can recall hidden food locations for weeks. Problem-solving skills: Can figure out how to open containers or manipulate objects to access food.

Interesting Facts

State bird of Massachusetts and Maine. Can lower its body temperature at night to conserve energy (a process called torpor). The number of “dee” sounds in its call signals the level of danger. Sometimes follows woodpeckers to find insects hidden in tree bark.
