Birds Of Japan 069-Marsh tit -日本の野鳥069-ハシブトガラ

Marsh Tit ハシブトガラ Scientific name: Poecile palustris

The Marsh Tit is a small, active songbird belonging to the tit family. It has a distinctive black cap, pale cheeks, brownish-gray upperparts and light underparts. Although its English name suggests a bird restricted to wetlands, it also inhabits woodland, forest edges and areas with mature trees. In Japan, the Marsh Tit is particularly associated with the forests of Hokkaido.

Key info for card

Habitat: Deciduous and mixed forests, broadleaf woodland, forest edges and wooded areas with mature trees.

Range in Japan: Primarily Hokkaido, where it is a resident breeder. Do not show it as a widespread resident across Honshu, Shikoku and Kyushu.

Diet: Insects, spiders, other small invertebrates, seeds and berries. It may store food for later use.

Season: Resident year-round in Japan.

Size: Approximately 12–13 cm long.

Nesting: Nests in tree cavities, including natural holes and old woodpecker cavities. The female typically incubates the eggs while the male helps provide food.

Behavior: Active and agile, often moving through branches and foliage in search of food. It may join mixed-species flocks outside the breeding season and can hide food in bark crevices for later consumption.

Conservation: Globally classified as a species of relatively low conservation concern, but local populations depend on suitable woodland and available nesting cavities. Protecting mature trees and forest structure supports its habitat.

The Marsh Tit has a glossy black cap, a small black bib beneath the bill, white cheeks and subdued brown-gray upperparts. It closely resembles the Willow Tit, so identification can require careful observation of its head markings, bill and calls.

In Japan, the Marsh Tit is especially useful to distinguish from the Willow Tit because the two species can occur in overlapping northern forest habitats.

The Marsh Tit (ハシブトガラ) is a small, resident songbird of Hokkaido's forests. Recognizable by its black cap, white cheeks and compact shape, it searches branches and foliage for insects, seeds and other food. Adaptable and energetic, this woodland tit sometimes stores food for later, making it a fascinating subject for observing the everyday lives of Japan's forest birds.

Marsh Tit ハシブトガラ

The Marsh Tit is a small passerine bird in the tit family, recognized by its black cap, dark bib, pale cheeks, and soft brown upperparts. Despite its name, it is not restricted to marshes and is commonly associated with mature deciduous woodland, mixed forests, and wooded areas with plenty of trees. It searches branches and foliage for insects, spiders, seeds, and other small food items.

Marsh Tits are active and agile foragers, often moving quickly through branches while giving their distinctive nasal calls. They may store seeds for later use, hiding them in crevices or beneath vegetation. In Japan, this species is found mainly in Hokkaido, where it inhabits suitable woodland throughout the year. It is easily confused with the closely related Willow Tit, so careful attention to its calls and identification features can be helpful.

ハシブトガラ Marsh Tit

ハシブトガラは、黒い頭頂部と喉元、白い頬、茶色みを帯びた背中が特徴の小型の野鳥です。シジュウカラ科に属し、主に落葉広葉樹林や針広混交林などの森林に生息しています。名前に「ハシブト」とありますが、くちばしだけでなく、頭部や翼の形、鳴き声なども近縁種の識別に役立つ特徴です。木の枝や葉の間を動きながら、昆虫、クモ、種子などを探します。

ハシブトガラは動きが素早く、枝から枝へ移動しながら、特徴的な声で頻繁に鳴きます。食べ物を後で食べるために、樹皮の隙間や植物の陰などに隠しておく習性もあります。日本では主に北海道に分布し、適した森林で一年を通して見られます。よく似たコガラと混同されることもあるため、くちばしの形や羽色、鳴き声などを注意深く観察することが識別のポイントです。
