Coal Tit

About

The Coal Tit (Periparus ater) is a small passerine bird in the tit family Paridae. It is a widespread and common resident breeder throughout temperate Eurasia and northern Africa. Known for its distinctive black cap, white cheek patches, and a prominent white patch on the nape, it is often found in coniferous and mixed woodlands, where it forages for insects and seeds.

Size & lifespan

Length

10-11.5 cm

Wingspan

17-21 cm

Weight

7-12 g

Lifespan

2-3 years (up to 6 years in the wild)

Diet

Omnivore (primarily insects, spiders, and seeds, especially conifer seeds)

Physical characteristics

Plumage

Adults have a glossy black head with prominent white cheek patches and a distinctive white patch on the nape. The back is greyish-blue, and the underparts are buffy-white, often with a yellowish wash on the flanks. The wings are dark with two white wing-bars. The tail is dark grey.

Beak shape

Small, conical, and pointed, black in color, adapted for picking insects and seeds.

Eye color

Dark brown.

Leg color

Dark grey to blackish.

Distinguishing features

The most distinctive features are the white nape patch, black cap, and white cheek patches. The two white wing-bars are also a good field mark.

Juvenile appearance

Juveniles are similar to adults but have a duller, more yellowish-buff wash on the underparts and cheek patches. The white nape patch may be less distinct, and the black cap can appear browner.

Seasonal changes

No significant seasonal plumage changes. Plumage may appear slightly duller or more worn outside of the breeding season due to feather abrasion.

Sexual dimorphism

Males and females are virtually identical in plumage. There are no significant visual differences.

How to identify

1. 1

   Head Pattern

   Look for the glossy black cap, prominent white cheek patches, and, most importantly, the distinct white patch on the nape (back of the neck).

2. 2

   Wing-bars

   Observe the two clear white wing-bars on the dark wings, a key distinguishing feature from Marsh and Willow Tits.

3. 3

   Size and Shape

   It's a small, compact tit, slightly smaller than a Blue Tit, with a relatively short tail.

4. 4

   Habitat

   Often found in coniferous trees, where its grey-blue back provides camouflage.

5. 5

   Vocalization

   Listen for its high-pitched, repetitive 'pee-choo pee-choo' song, which is faster and higher than a Great Tit's.

Habitat & range

Biomes

Temperate forests, coniferous forests, mixed woodlands, parks, and gardens.

Geographic range

Widespread across Eurasia, from Western Europe to Japan, and in parts of North Africa. Absent from Iceland and parts of northern Scandinavia.

Elevation range

Sea level up to 2,000 meters, sometimes higher in mountainous regions.

Preferred environments

Prefers coniferous forests (spruce, pine, fir) but also inhabits mixed woodlands, parks, and large gardens, especially those with mature trees. Often found in the canopy and mid-story.

Behavior

Activity time

Diurnal.

Feeding habits

Primarily insectivorous during the breeding season, feeding on caterpillars, aphids, and other small invertebrates. In autumn and winter, their diet shifts to seeds, particularly those of conifers, which they often extract from cones. They are known to hoard food, caching seeds and insects in bark crevices, moss, or under lichens for later retrieval.

Social behavior

Often solitary or in pairs during the breeding season. In autumn and winter, they frequently join mixed-species foraging flocks with other tits, goldcrests, and treecreepers.

Flight pattern

Undulating flight, typical of tits, with rapid wing beats interspersed with short glides.

Migration pattern

Mostly resident throughout its range. Some northern populations may undertake short-distance altitudinal or irruptive movements in harsh winters or when food resources are scarce.

Territoriality

Territorial during the breeding season, with males defending nesting sites and foraging areas. Outside of breeding, they are less territorial and more tolerant of other birds.

Breeding & reproduction

Breeding season

April to July, typically two broods per year.

Nesting habits

Nests are usually built in holes in trees, stumps, or banks, often utilizing old mouse holes or crevices. They may also use nest boxes. The nest is a cup-shaped structure made of moss, hair, and feathers.

Clutch size

6-11 eggs (average 7-9).

Egg description

6-11 eggs, white with reddish-brown speckles, particularly at the broader end. Approximately 14 x 11 mm.

Incubation period

14-16 days, primarily by the female.

Fledging period

18-20 days after hatching. Both parents feed the young.

Parental care

Both parents participate in feeding the nestlings and fledglings. The female incubates, while the male brings food to her and later to the young.

Where to find

Field tips

1. Look in the canopy. Coal Tits often forage high in trees, especially conifers, meticulously searching for insects and seeds.
2. Listen for their song. Their distinctive 'pee-choo' song is a good way to locate them, especially during spring.
3. Observe mixed flocks. In winter, join mixed-species tit flocks; Coal Tits are often part of these groups.
4. Check bird feeders. They are regular visitors to feeders, particularly those offering sunflower seeds or suet.
5. Watch for food caching. In autumn, observe them hiding seeds in bark crevices, a characteristic behavior.

Fun facts

• Coal Tits are renowned for their food-hoarding behavior, caching thousands of seeds and insects, especially in autumn, to survive the winter months. They have an excellent memory for these hidden stashes.
• Despite their small size, Coal Tits are quite hardy and can survive harsh winter conditions, thanks to their ability to find and remember cached food.
• The scientific name 'Periparus ater' means 'dark titmouse', referring to its black cap and overall darker appearance compared to some other tits.
• They are highly acrobatic foragers, often hanging upside down from branches to access insects and seeds.
• There are numerous subspecies of Coal Tit across its vast range, showing slight variations in plumage color and size, reflecting adaptations to local environments.
