19-3-2016 MONTE CORONA, VALENCIA - EURASIAN BLACKCAP (FEMALE)

The Eurasian blackcap (Sylvia atricapilla) is a common and widespread warbler that breeds in much of Europe, western Asia, and northwestern Africa. Its rich and varied song has led to the blackcap being described as the "mock nightingale" and it has been featured in literature, films, and music.

The Eurasian blackcap is mainly grey in color with distinct male and female plumages. The adult male has olive-grey upperparts, other than a paler grey nape and a neat black cap on the head. The underparts are light grey, becoming silvery white on the chin, throat, and upper breast. The tail is dark grey, with an olive tint to the outer edge of each feather. The bill and long legs are grey, and the iris is reddish brown. The female resembles the male but has a reddish-brown cap and a slightly browner tone to the grey of the upperparts. Juveniles are similar to the female, but their upperparts have a slight rufous tinge, and the breast and flanks have a more olive tone; young males have darker brown cap than their female counterparts.

Eurasian blackcaps breed in much of Europe, western Asia, and northwestern Africa. They are partial migrants; birds from the colder areas of their range winter in northwestern Europe, around the Mediterranean, and in tropical Africa. Some German birds have adapted to spending the winter in gardens in Great Britain and Ireland. Eurasian blackcaps breed in mature deciduous woodlands, with good scrub cover below the trees, and may also be found in parks, large gardens, and overgrown hedges. The preferred winter habitat around the Mediterranean is scrub and olive orchards, while in Africa they occur in cultivated land, acacia scrub, mangroves, and forest.

Eurasian blackcaps are very active birds. They are usually found singly but may form loose groups during migration. They feed by the day mainly picking prey off foliage and twigs, but may occasionally hover, flycatch or feed on the ground. Blackcaps eat a wide range of small fruit and squeeze out any seeds on a branch before consuming the pulp. They defend good winter food sources, and at garden feeding stations they don't hesitate to repel competitors as large as starlings and blackbirds. Eurasian blackcaps are known for their beautiful loud song. The males' song is a rich musical warbling, often ending in a loud high-pitched crescendo, which is given in bursts of up to 30 seconds. In some geographically isolated areas, such as islands, peninsulas, and valleys in the Alps, males sing a simpler fluting song. The main call of Eurasian blackcaps is a hard 'tac-tac', like stones knocking together, and other vocalizations include a squeaking sweet alarm, and a low-pitched trill. Blackcaps may sometimes mimic the song of other birds, especially preferring to copy the garden warbler and the common nightingale.

2-3-2024 RIO SERPIS GANDIA, VALENCIA - EURASIAN BLACKCAP (FEMALE) (Sylvia atricapilla)

The Eurasian blackcap (Sylvia atricapilla), usually known simply as the blackcap, is a common and widespread typical warbler. It has mainly olive-grey upperparts and pale grey underparts, and differences between the five subspecies are small. Both sexes have a neat coloured cap to the head, black in the male and reddish-brown in the female. The male's typical song is a rich musical warbling, often ending in a loud high-pitched crescendo, but a simpler song is given in some isolated areas, such as valleys in the Alps. The blackcap's closest relative is the garden warbler, which looks quite different but has a similar song.

The blackcap breeds in much of Europe, western Asia and northwestern Africa, and its preferred habitat is mature deciduous woodland. The male holds a territory when breeding, which is defended against garden warblers as well as other blackcaps. The nest is a neat cup, built low in brambles or scrub, and the clutch is typically 4–6 mainly buff eggs, which hatch in about 11 days. The chicks fledge in 11–12 days, but are cared for by both adults for some time after leaving the nest. The blackcap is a partial migrant; birds from the colder areas of its range winter in scrub or trees in northwestern Europe, around the Mediterranean and in tropical Africa. Some birds from Germany and western continental Europe have adapted to spending the winter in gardens in Great Britain and Ireland. Insects are the main food in the breeding season, but, for the rest of the year, blackcaps survive primarily on small fruit. Garden birds also eat bread, fat and peanuts in winter.

Despite extensive hunting in Mediterranean countries and the natural hazards of predation and disease, the blackcap has been extending its range for several decades, and is classified by the International Union for Conservation of Nature as least concern. Its rich and varied song has led to it being described as the "mock nightingale" and it has featured in literature, films and music. In Messiaen's opera Saint François d'Assise, the saint is represented by themes based on the blackcap's song.

8-1-2024 VILLALONGA TUNNELS, VALENCIA - EURASIAN BLACKCAP (FEMALE) (Sylvia atricapilla)

The blackcap is a mainly grey warbler with distinct male and female plumages. The nominate subspecies is about 13 cm (5.1 in) long with a 7–8 cm (2.8–3.1 in) wing length. The weight is typically 16–25 g (0.56–0.88 oz), but can be up to 31 g (1.1 oz) for birds preparing to migrate. The adult male has olive-grey upperparts, other than a paler grey nape and a neat black cap on the head. The underparts are light grey, becoming silvery white on the chin, throat and upper breast. The tail is dark grey, with an olive tint to the outer edge of each feather. The bill and long legs are grey, and the iris is reddish brown. The female resembles the male, but has a reddish-brown cap and a slightly browner tone to the grey of the upperparts. Juveniles are similar to the female, but their upperparts have a slight rufous tinge, and the breast and flanks have a more olive tone; young males have a darker brown cap than their female counterparts. This species is unmistakable; other dark-headed Sylvia species, such Sardinian and Orphean warblers have extensive black on the head instead of a small cap. They are also larger and have white edges on the tail.
