This initiative combines leisure, environmental education, and the dissemination of the Territory's natural heritage. The program kicks off on April 18 in Valderejo Natural Park, at the Lalastra Parketxe, with a guided visit focused on alpine birds. Participants will learn about the role of these species in the ecosystem and the challenges they face due to climate change, through both theoretical introduction and direct observation in nature.

In Aizkorri-Aratz, on April 19, a scientific bird banding workshop will be held at the Araia Parketxe. Led by an accredited bander, this activity will provide a close look at the process of capturing, collecting biological data, banding, and releasing birds. It is an educational and environmental awareness proposal for both adults and children, with children required to be accompanied.

Gorbeia Natural Park will host the Amphibian Night on April 24 and 25 at the Sarria Parketxe. This nocturnal experience will offer insight into one of the planet's most threatened vertebrate groups. During the activity, various sites will be visited, including the parketxe pond and the wetlands around Marakalda, where different species can be observed in their natural habitat.

Furthermore, Izki Natural Park will feature several activities specifically designed for families. On April 18, at the Korres Parketxe, a craft workshop for children aged 7 and above will take place, where they will create an articulated mobile inspired by the middle spotted woodpecker, using natural materials and fostering creativity.

Additionally, for April 25, a dry wicker construction workshop has been scheduled at the Korres recreational area. Participants will collaboratively build a hut-like structure, learning basic weaving and assembly techniques with natural materials in the heart of nature. All activities are free and require prior registration through the websites of each natural park.
