# Northern Mockingbird (*Mimus polyglottos*)

> The northern mockingbird (Mimus polyglottos) is a medium-sized grey North American songbird famous for extraordinary vocal mimicry — it can learn and replicate 200 or more songs, calls, and sounds, including other birds, frogs, insects, and even car alarms. Unmated males may sing continuously through the night during breeding season.

## The master mimic

The northern mockingbird is one of the most accomplished vocal mimics in the animal kingdom. It can learn and perform more than 200 distinct songs, calls, and environmental sounds during its lifetime, adding new ones continuously. The Latin name Mimus polyglottos means 'many-tongued mimic.' It does not simply copy sounds once — it integrates them into long, complex sequences, cycling through its repertoire and repeating each phrase several times before switching to the next. Individuals with larger repertoires attract mates more successfully, so mimicry is a genuine fitness signal.

## Night singing and territorial defence

Mockingbirds are highly territorial and will vigorously defend their area against much larger birds and animals, sometimes dive-bombing cats, dogs, and people who approach their nest. Unmated males sing continuously through the night during breeding season — a behaviour admired by some and a source of sleep complaints from others. Once paired, night singing typically decreases. Their territoriality is intense enough that they will memorise and respond aggressively to specific individual people they identify as a threat.

## Appearance and range

The northern mockingbird is a slender songbird with grey upper parts, whitish underparts, and white patches on its wings that flash conspicuously in flight. It is widespread across the continental United States, southern Canada, Mexico, and the Caribbean, and is a year-round resident in most of its range — it does not make long migrations. It is the official state bird of five US states.

## Diet and wing-flashing

Mockingbirds shift their diet by season. In summer they eat mainly insects; in autumn and winter they switch to berries, fruit, and seeds. They forage on the ground with a distinctive run-and-stop style, and often spread their wings open in a display that may startle insects into moving, making them easier to catch. This wing-flashing behaviour is also used in territorial displays.

## Frequently asked questions

### How many songs can a mockingbird imitate?

Individual northern mockingbirds can learn over 200 distinct songs and sounds during their lifetime, and they keep adding new ones. Males generally have larger repertoires than females and use their song range to attract mates and defend territory.

### Why do mockingbirds sing at night?

Unmated males sing at night — particularly under bright conditions like a full moon or near streetlights — to advertise their availability to females. Once paired, night singing usually stops. The behaviour peaks in spring and early summer.

### Are mockingbirds aggressive?

Yes — they are notably territorial and will dive-bomb and physically strike animals many times their size, including cats, dogs, hawks, and people, if they perceive a threat to their nest. The attacks are genuine and can include contact.

### Which states have the mockingbird as their state bird?

The northern mockingbird is the official state bird of Arkansas, Florida, Mississippi, Tennessee, and Texas.

### What does the mockingbird eat?

In warm months mockingbirds eat mainly insects; in autumn and winter they rely more on berries, fruit, and seeds. They are versatile omnivores that forage on the ground and in shrubs, and their diet shifts with seasonal availability.
