Red-flanked Bluetail

Introduction
Once regarded as an extreme vagrant, records of this relative of the Robin have increased dramatically, likely following a marked population increase in the forests of eastern Finland, where it was first recorded breeding in the 1940s.
This migratory species breeds from Finland east to Kamchatka and winters across parts of China.

Biology
Survival and Longevity
Survival is shown as the proportion of birds surviving from one year to the next and is derived from bird ringing data. It can also be used to estimate how long birds typically live.
