ヒガラ

The coal tit, Periparus ater, is a small, active passerine bird in the family Paridae distributed across a vast range from western Europe through central Asia to the Pacific coast of Russia, China, and Japan. It inhabits predominantly coniferous and mixed forests, showing a particular affinity for spruce and fir woodland where it forages acrobatically among needles and bark for insects, spiders, and seeds. In Europe, including Scandinavia and the Benelux countries, it is a familiar resident of pine and spruce forests at all elevations from sea level to treeline. The coal tit is recognized by its distinctive black cap, white cheek patches, a white spot on the nape that distinguishes it from other tits, and buff underparts. It is one of the smallest members of the Paridae family, measuring around 10–11 centimeters in length. Coal tits are notable food hoarders, caching seeds and invertebrates in bark crevices and under moss to sustain themselves through winter. The species is monogamous and nests in natural tree holes, old woodpecker cavities, or nest boxes. It is assessed as Least Concern by the IUCN with a large, stable population and extensive range across Eurasian coniferous and mixed forests.
