💡 Everyday Comparisons for Size, Mass & Speed

💡 Its tail alone is about 40 cm long, well over half of its total length of 65 cm (40 ÷ 65 ≈ 62%, Comparison).
💡 Because flocks fly in single file, it is also called the 'long-tailed formation' in Taiwan (Tri-Mountain National Scenic Area Administration).
💡 It can be seen in low- to mid-elevation broadleaf forests in Taiwan such as Lion's Head Mountain (Tri-Mountain National Scenic Area Administration).

📖 1. Overview

The Taiwan Blue Magpie is a crow-family bird endemic to Taiwan that flies in single-file flocks trailing its long tail.

🦴 2. Anatomy & Morphology

Its body is mostly blue with a paler belly, a black head, neck, and breast, a red bill and feet, and yellow eyes. Its wingtips are spotted with white, and its very long tail feathers have white tips.

🔍 3. Ecology & Behavior

It is omnivorous, eating seeds, fruits, and insects. During the April–August breeding season, it builds a shallow saucer-shaped nest of twigs, vines, and grass on horizontal treetop branches and lays 4–6 eggs, using a helper system in which individuals other than the parents also help raise the chicks.
