Sombre Tit

Poecile lugubris

How to recognise a sombre tit?

General appearance

The sombre tit is a small bird species approximately 14cm in length. Its overall coloration is predominantly a smoky bluish-grey, with a black crown and nape that elongate towards the back. The chest and belly are pale grey, and the bird also features a robust, dark bill and sturdy legs.

Male vs female

Sombre tits show minimal sexual dimorphism, meaning males and females are somewhat similar. Males are typically larger and slightly darker with more black on the head; however, these differences are often difficult to distinguish in the field.

Juvenile

Juvenile sombre tits resemble adults but have lighter plumage with a brownish hue. They also feature less black on the head and a slightly smaller bill. Juvenile plumage gradually darkens and becomes more like adult plumage after the first moult.

Size

4.7 - 5.9 in/0.5 - 0.7 oz

Habitat

Primary habitat

The Sombre Tit prefers coniferous and deciduous woodlands in mountainous regions.

Additional range

This bird is found across Southeast Europe and Western Asia. It tolerates a temperate climate, but can also surprisingly survive in semi-desert areas.

What do sombre tits like to eat?

Natural diet

The sombre tit primarily feeds on insects, caterpillars, and other small invertebrates found in its natural habitat. It forages through foliage, tree bark, and undergrowth to find its prey. During the breeding season, it relies heavily on protein-rich insects to feed its young. Additionally, it consumes various seeds and berries, particularly when insect availability is low.

Bird feeders

At bird feeders, the sombre tit often consumes sunflower seeds, suet, and peanuts. These high-energy foods supplement its diet, especially during colder months or in areas with limited natural food sources. The sombre tit is attracted to both seed-filled feeders and suet hampers, which provide essential fats and proteins.

What does a sombre tit sound like?

The sombre tit has a varied repertoire of vocalizations. Its most typical call is a sharp "pit" or "pitchew," often given in series or combined into a chattering alarm call. The song, typically delivered from a high perch, consists of a set of plaintive, melancholic whistles, repeating a pattern of "pee-poo-pee" or "pee-pooh" notes. Occasionally, it produces more complex, rapid sequences of notes. The sounds are often muted and rather mournful, matching its sombre name.

Willow Tit

Poecile montanus

How to recognise a willow tit?

General appearance

The Willow Tit (Poecile montanus) is a small, plump songbird with a robust body. Its plumage primarily consists of grey, brown, and white shades. The head is capped in glossy black extending to the nape, contrasting sharply with the pale cheeks. The upperparts are brownish-grey while the underparts are white, with sides tinged buff-brown. Its wings and tail boast a darker hue. An essential characteristic is a small black bib under its chin.

Male vs female

There is minimal sexual dimorphism in Willow Tits, making it hard to distinguish males from females by appearance. Both sexes have similar coloration and size. Thus, identification between genders is generally achieved through their distinct vocalizations.

Juvenile

Juvenile Willow Tits resemble the adults, but the glossy black cap is duller and they lack the black bib of mature birds. Additionally, juveniles exhibit a paler plumage with a more yellowish-brown hue. As they age, the coloration gradually darkens, approaching the adult appearance by their first winter.

Size

4.3 - 4.7 in/0.3 - 0.5 oz

Habitat

Primary habitat

The willow tit favors damp deciduous and mixed forests in cool and temperate climate zones, specifically thriving in willow, alder, and birch trees.

Additional range

Astonishingly, this bird can also be found in scrubby areas and gardens. It mostly inhabits the Palearctic region, with a range extending across Europe and Asia to Japan.

Range Map

What do willow tits like to eat?

Natural diet

The willow tit primarily consumes insects and spiders, which provide essential protein, particularly during the breeding season. These birds forage for caterpillars, beetles, aphids, and other small invertebrates found among foliage and bark. Seeds from trees like birch and alder, as well as a variety of berries, form a significant part of their diet, especially during the colder months when insects are scarce.

Bird feeders

At bird feeders, willow tits are known to eat sunflower seeds, peanuts, and suet. These foods offer a convenient and reliable source of nourishment, particularly during winter when natural food sources are limited. The willow tit's preference for sunflower seeds is widespread among passerines due to their high energy content.

What does a willow tit sound like?

The willow tit produces a variety of vocalizations; its common call is a sharp, nasal "tsit-tsit" or a scolding “chaa-chaa-chaa”. This bird's song, mainly produced by males, is a series of variable clear, high-pitched notes vibrating at a frequency of 3-5 kHz, with a "see-see-see-see" structure, and can contain imitations of other birds. Each song sequence lasts about 2 seconds. During courtship, it emits a repeated, faint "zeee" sound.

How to tell the Sombre Tit from the Willow Tit

Visual differences

The Sombre Tit is slightly larger at about 5-6 inches long, with a smoky bluish-grey plumage, pale grey chest, and a dark, robust bill. It has a distinct black crown and nape. In contrast, the Willow Tit is smaller, around 4.3-4.7 inches, with browner upperparts, a glossy black cap, and pale cheeks. Its underparts are white with buff-brown sides and it features a small black bib under the chin. The Sombre Tit is more uniformly colored, whereas the Willow Tit has more contrast in its plumage.

Key differences and behavior

The Sombre Tit and Willow Tit both display distinct behaviors and habitat preferences. Sombre Tits prefer higher altitudes (3,200 to 5,250 feet) in coniferous and deciduous woodlands, thriving in temperate to semi-desert areas. In contrast, Willow Tits favor damp deciduous and mixed forests, especially near water. For nesting, Sombre Tits utilize pre-existing cavities, whereas Willow Tits are adept excavators, carving their own sites in rotten wood. Sombre Tits have elaborate courtship displays, while Willow Tits engage in singing and fluttering flights. Both species share similar diets of insects and seeds, especially at feeders where they favor sunflower seeds and suet. Sombre Tits, however, are slightly heavier (0.53-0.67 oz) compared to Willow Tits (0.28-0.53 oz). Both species exhibit minimal sexual dimorphism, making visual identification challenging, so behavior and habitat are key for differentiation.
