Kulmasiipiä

Kulmasiipiä is a Finnish term that translates to "corner wings" or "angle wings." It primarily refers to a specific type of bird, particularly a small bird that builds its nest in corners or sheltered angles. While not a formal taxonomic classification, it is a descriptive colloquialism used in certain regions of Finland to identify birds that favor such nesting locations. The species most commonly associated with this description are typically small passerines that seek protection from the elements and predators in nooks and crannies, such as those found on buildings or within natural structures.

The behavior of nesting in corners is a survival strategy. These sheltered spots offer a degree of camouflage and protection from wind and rain, which can be crucial for the survival of young birds. The term "kulmasiipiä" highlights this observable characteristic of the birds' nesting habits. It is important to note that the specific bird species referred to as "kulmasiipiä" can vary depending on local dialect and the bird populations present in a particular area. However, the underlying concept remains consistent: birds that utilize angles and corners for their nests. This folk term reflects a common observation of nature within Finnish rural and urban environments.
