Cantabrian capercaillie: captive breeding to prevent its extinction

Published on April 25, 2026 | Translated from Spanish

The Ministry of Environment of Castilla y León has intensified its commitment to captive breeding of the Cantabrian capercaillie, a species in critical danger of extinction. The program, centered on the Sobrescobio facility (Asturias) and the Junta's installations in León, aims to increase the population through controlled reproduction and specific care to improve the survival rate of chicks.

Technology and biology at the service of the capercaillie 🧬

The facilities feature climate control systems that replicate the capercaillie's natural habitat, including variable light and humidity cycles. Automated incubators are used to record the weight and temperature of eggs in real time. Additionally, personalized diets with vitamin supplements are applied, and the health of each specimen is monitored through genetic analysis to avoid inbreeding. These advances allow control over factors that are lethal for the species in the wild.

Good thing they don't need wifi to hook up 😂

While technicians rack their brains over thermostats and DNA analysis, captive capercaillies only think about two things: eating and, with a bit of luck, perpetuating the species. Of course, at least they don't have to deal with dating apps or the social pressure of finding a mate before the program's resources run out. If this works out, maybe in a few years we'll see capercaillies lining up to book an appointment at the breeding center.
