Coal Tit

Informazioni

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 Europe and Asia, often found in coniferous and mixed woodlands. Known for its distinctive black cap, white cheek patches, and a prominent white patch on the nape, it is an active and agile feeder, often seen clinging to branches and cones.

Caratteristiche fisiche

Piumaggio

Adults have a glossy black head with prominent white cheek patches and a distinctive white patch on the nape. The back is slate-grey, and the underparts are buffy-white, often with a slight yellowish or brownish wash, particularly on the flanks. The wings and tail are dark grey with faint paler edgings to the flight feathers. There are two narrow white wing-bars.

Forma del becco

Small, conical, and pointed; black in color.

Colore degli occhi

Dark brown.

Colore delle zampe

Dark grey to blackish.

Caratteristiche distintive

The most distinctive features are the glossy black cap, the large white cheek patches, and especially the prominent white patch on the nape (back of the neck), which is unique among European tits. The two white wing-bars are also a good field mark.

Aspetto giovanile

Juveniles resemble adults but have duller plumage. The black areas of the head are less glossy, more sooty-brown, and the white cheek patches and nape patch are often tinged yellowish or buffy. The underparts are also more yellowish-buff.

Cambiamenti stagionali

No significant seasonal plumage changes. The plumage remains consistent throughout the year, though it may appear slightly worn or faded towards the end of the breeding season before the annual molt.

Dimorfismo sessuale

Males and females are generally monomorphic in plumage, appearing identical. There might be slight size differences, with males being marginally larger on average, but this is not discernible in the field.

Come identificare

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). This nape patch is the key identifier.

2. 2

   Plumage Coloration

   Note the slate-grey back and buffy-white underparts. The two narrow white wing-bars are also a good feature to observe.

3. 3

   Size and Shape

   It's a small, compact tit, slightly smaller than a Great Tit and similar in size to a Blue Tit, but with a more slender build than the latter.

4. 4

   Behavior

   Observe its active foraging style, often hanging upside down or clinging to conifer cones. Its preference for coniferous trees is also a strong clue.

5. 5

   Vocalizations

   Listen for its characteristic 'pee-choo, pee-choo' song, which sounds like a bicycle pump, and its sharp 'tsee-tsee-tsee' calls.

Habitat e areale

Biomi

Temperate forests, boreal forests, mixed woodlands, parks, gardens.

Areale geografico

Widespread across Europe and Asia, from the British Isles and Iberia eastward through Scandinavia, central and eastern Europe, Russia, and across Siberia to Japan and China. Also found in parts of North Africa.

Fascia altitudinale

Sea level up to 2,000 meters, occasionally higher in mountainous regions (e.g., up to 3,000 meters in the Himalayas).

Ambienti preferiti

Strong preference for coniferous forests (pine, spruce, fir), but also common in mixed woodlands, especially those with a significant conifer component. Can be found in deciduous woods, parks, and large gardens, particularly outside the breeding season.

Comportamento

Periodo di attività

Diurnal.

Abitudini alimentari

Primarily insectivorous during spring and summer, feeding on insects, spiders, and their larvae. In autumn and winter, their diet shifts to seeds, especially conifer seeds, and nuts. They are adept at extracting seeds from cones and will also feed on beech mast and acorns. Known for caching food (seeds and nuts) in crevices, under bark, or in the ground for later retrieval, a crucial survival strategy in winter. They forage actively, often hanging upside down or clinging to the tips of branches.

Comportamento sociale

During the breeding season, they are territorial and typically found in pairs. Outside the breeding season, they often join mixed-species foraging flocks, particularly with other tit species, Goldcrests, and Treecreepers. They can be quite bold at bird feeders.

Tipo di volo

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

Migrazione

Mostly resident throughout their range, but some northern and eastern populations undertake short-distance irruptive movements in years of poor food supply. Juveniles may disperse further from their natal sites. Generally considered a sedentary species.

Territorialità

Highly territorial during the breeding season, defending their nesting and foraging areas from conspecifics and sometimes other small birds.

Riproduzione

Stagione riproduttiva

Typically April to July, with peak activity in May and June. Often raises two broods per year.

Abitudini di nidificazione

Nests are usually built in holes in trees (often old woodpecker holes), stumps, or banks, but also readily uses nest boxes. They prefer small, dark cavities. The nest is a cup-shaped structure made of moss, hair, wool, and feathers, often lined with finer materials.

Dimensione della covata

7-11 eggs, sometimes up to 13.

Descrizione dell'uovo

Eggs are white with reddish-brown speckles, particularly concentrated at the broader end. They are small and oval-shaped.

Periodo di incubazione

14-16 days, primarily by the female.

Periodo di involo

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

Cure parentali

Both parents participate in feeding the young. The female incubates, while the male brings food to her and later to the nestlings. After fledging, the young are fed by both parents for a short period before becoming independent.

Dove trovarlo

Consigli sul campo

1. Listen for the song. The repetitive 'pee-choo' song is often the first indication of a Coal Tit's presence, even before you see it.
2. Check conifer trees. Focus your search on coniferous trees, where they actively forage for insects and seeds. Look for small, active birds moving quickly through the branches.
3. Observe mixed flocks. In autumn and winter, join mixed-species tit flocks. Coal Tits are often part of these groups, moving through the canopy.
4. Look for the nape patch. Once you spot a small tit, quickly scan for the white patch on the back of its neck – this is the definitive field mark for a Coal Tit.

Curiosità

• The Coal Tit is one of the smallest European tits, often overlooked due to its size and preference for dense foliage.
• It is an expert at caching food, sometimes storing thousands of seeds and nuts in a season, remembering the locations for later retrieval.
• Despite its name, 'Coal' refers to its dark cap, not its habitat or diet.
• Several subspecies exist across its vast range, showing slight variations in plumage coloration, particularly in the extent of buff or grey on the underparts and back.
• Its ability to extract seeds from conifer cones makes it a vital disperser of conifer seeds in its ecosystem.
