A Family of 'Ginkkori Ddaksae' Appears on Munsusan Mountain in Ulsan

Endangered Wildlife Category II ... Efforts Needed to Create a Safe Breeding Environment

A family of endangered long-tailed flycatchers was recently spotted in the Munsusan Valley, Ulju-gun, Ulsan.

[Asia Economy Yeongnam Reporting Headquarters Reporter Kim Yong-woo] The discovery of a breeding nest of the endangered "Ginkkori Daksae" (Long-tailed Robin) has attracted attention.

According to Ulsan City on the 6th, a breeding nest of the Long-tailed Robin, a summer migratory bird and a Class II endangered wild species designated by the Ministry of Environment, was confirmed in the Munsusan Valley of Ulju-gun.

During the monitoring of waterfowl habitats and endangered/protected wild species in the Ulsan area, including the Taehwa River, the investigation team, who received a report on June 20 that the calls of the Long-tailed Robin and the Pal-saekjo (Fairy Pitta) were heard, conducted an exploration and observed a female incubating eggs in a nest among branches near the valley.

Later, when the investigation team revisited the nest on June 29, they captured scenes of 4 to 6 chicks estimated to be competing by opening their beaks to receive food from their mother.

The female parent bird brought food several times, and occasionally the male also brought food to feed the chicks before leaving the nest.

The Long-tailed Robin, belonging to the family Muscicapidae, arrives in early May to breed. The eggs are incubated for two weeks, and the chicks grow for 8 to 12 days before moving to a new habitat. After breeding, they return to their wintering grounds in Southeast Asia in early August.

Until recently, it was called "Samgwangjo," a Japanese name. The Korean Ornithological Society renamed it Long-tailed Robin, highlighting the characteristic that the male's tail is more than three times longer than the female's.

It is known that the female accepts the male with the long tail as a mate. The longer the tail, the healthier the bird is considered.

An official from Ulsan City said, "The breeding environment of the Long-tailed Robin is deteriorating due to various developments," and added, "We will continue efforts to create a safer breeding environment through monitoring of summer and winter migratory birds visiting Ulsan."
