Grive à gorge noire

Turdus atrogularis

Une grive sombre, aux couleurs discrètes, des forêts de moyenne à haute altitude. Hiverne généralement à des altitudes plus élevées, mais se déplace occasionnellement vers les zones de piémont et de plaine. Le mâle est unique, avec un dos gris, un ventre blanc et la gorge et la poitrine d'un noir de jais. Les femelles sont brun strié en dessous et peuvent être confondues avec la Grive à gorge rousse, mais les femelles de la Grive à gorge noire ne montrent pas d'orange sur la gorge ou les côtés de la queue ; les seules couleurs chaudes chez cet oiseau sont le dessous des ailes orangé. Dans les zones de chevauchement, attention aux hybrides qui peuvent présenter des caractéristiques des deux espèces. Le chant consiste en diverses phrases répétées ; le cri comprend un « chekchekchek » grave et un « tseee » aigu et fin.

Identification

This is a large and distinctive thrush. The male has black from the chin to the breast with a greyish black tail. The upperparts are grey and the underparts are whitish with orange-red underwing coverts. Females and immatures are similar but the black on the throat and breast is replaced with dusky streaking.

Taxonomie

The scientific name comes from Latin. Turdus is "thrush" and the specific atrogularis is derived from ater, "black", and gula, "throat". Formerly considered conspecific with the red-throated thrush T. ruficollis but now considered a separate species.

Répartition et habitat

The breeding range of the black-throated thrush extends from the extreme east of Europe to Western Siberia and north-west Mongolia. The wintering range extends from the Middle East, although uncommon in the Arabian Peninsula to eastern Myanmar. As a vagrant it has occurred in Japan, Thailand, and Taiwan as well as to most of Europe west of its normal range. Black-throated thrushes breed along the edges of clearings in coniferous or mixed deciduous forest, often in the undergrowth of Siberian Pine Pinus sibirica or mixed spruce fir forest, especially along watercourses or in swampy areas.

Comportement

Breeds solitarily or in loose aggregations of pairs in late May through to late July. The nest is made of grasses and thin twigs bound with earth and lined with fine grasses, moss or lichens. The nest is usually placed within 1.5 to 2m of the ground, sometimes on the ground. Otherwise the behaviour is similar to that of the fieldfare T. pilaris. In winter often found in large flocks with other thrushes such as Tickell's thrush T. unicolor, eye-browed thrush T. obscurus and mistle thrush T. viscivorus, on migration often with dusky thrush. Roosts in dense evergreen vegetation. Feeds on the ground on invertebrates and also feeds on various berries, cherries and some seeds.
