Habits and Lifestyle
Taiwan blue magpies are not very afraid of people. They can be found near huɱaп residences in the mountains or newly cultivated lands. They are gregarious and are usually found in groups of three to twelve. The birds often fly in a line, following each other. This is someᴛι̇ɱes called “long-tailed formation”.

Similar to other members of the crow family, they have a raucous call which is described as a high-pitched cackling chatter, kyak-kyak-kyak-kyak. Other calls include ga-kang, ga-kang, kwee-eep and gar-suee.

Diet and Nutrition
Taiwan blue magpies are scavengers and omnivores. Their diet includes snakes, rodents, small insects, carrion, eggs and chicks of other birds, plants, fruits, and seeds. They also feed on food waste of huɱaпs. They someᴛι̇ɱes store leftovers on the ground and cover them with leaves for future retrieval. Someᴛι̇ɱes they store food in the leaves or branches.
Mating Habits
The breeding season is from March to July. The Taiwan blue magpie is monogamous. Females incubate eggs while males help with nest building and feeding. Their nests are built on high branches of trees. The nest is in the shape of a bowl and is made of twigs. Usually there are 3–8 eggs in a clutch. Eggs are light green in color, with brown marks. Hatching takes 17–19 days. There are 3–7 chicks per nest. Chicks leave the nest after 21–24 days, and can start flying for short distances after a few days. Some pairs breed a second ᴛι̇ɱe after this. The Taiwan blue magpie has helpers at the nest, mostly juveniles from previous breeding seasons. They help to feed the chicks and defend the nest. Taiwan blue magpies have a strong nest defence behaviour, and will attack intruders until they leave.
Population threats
Taiwan blue magpies may be hit by cars or captured by huɱaпs. They are also killed by predators, such as the crested goshawk, white-bellied sea eagle, spot-bellied eagle owl and the Gurney’s eagle.
Population number
The IUCN Red List of Threatened Species has currently assessed the species to be of least concern as it does not meet the criteria to be vulnerable. The population trend is suspected to be stable. Due to its endemism, however, the Taiwan blue magpie has been listed as other conservation-deserving wildlife (Chinese: 其他應予保育之野生動物) and protected by Taiwan’s Wildlife Conservation Act (Chinese: 野生動物保育法).

There is a small population of red-billed blue magpies that has been introduced to Wuling Farm in Taichung County (now part of Taichung City). In 2007, three hybrid chicks were found in a nest in Taichung, with red-billed and Taiwan magpie parents tending them. This caused some concern to conservationists, given the decline of the Taiwan hwamei due to the invasion of the Chinese hwamei. However, the Endemic Species Research Institute of Taiwan has been working to control red-billed magpie populations by capturing individual birds and relocating their nests.
