The article highlights the unique capabilities of the migratory bird known as the piiritaja, or the bar-tailed godwit, which spends a significant portion of its life in the air. This bird is remarkable for its ability to feed, sleep, and even mate while in flight. In the first two to three years of its life, when the bird is not yet mature, it may not even rest its feet on land, indicating a highly adapted lifestyle suited to migration. Once it becomes a breeding adult, it will still return to the same location within its colony to nest, a behavior that shows its loyalty to its breeding grounds.

In addition, the article notes that the piiritaja has become more of an urban bird due to a decrease in suitable nesting sites in nature, particularly old trees with hollows. As a result, after renovations to buildings, it is now common to see this bird checking out areas where it previously had nests, illustrating its adaptability and resilience in changing environments. This shift to urbanization highlights the impact of habitat loss on wildlife and raises questions about the conservation of such species.

The article presents an intriguing look at the piiritaja, not only focusing on its biological and behavioral characteristics but also addressing the broader environmental changes affecting its habitat. The findings underscore the need for continued research and conservation efforts to ensure that these birds, as well as other species facing similar challenges, are preserved for future generations.
