Kolipázis

Kolipázis is a term used in ornithology to describe a specific behavior observed in certain bird species, particularly members of the family Corvidae, which includes crows, ravens, and jays. It refers to the act of a bird carrying food in its beak for a significant distance or for later consumption by itself or its offspring. This behavior is a form of food caching or hoarding, a common survival strategy among many animal species.

The term "kolipázis" is derived from Greek roots, with "koli" relating to food or eating and "pázis" suggesting holding or carrying. While not as widely known as terms like "caching," it specifically highlights the carrying aspect of food provisioning. Birds employing kolipázis often select food items that are easy to transport and can be stored in a suitable location, such as a hidden cache in the ground, a tree cavity, or a dense thicket.

The primary purpose of kolipázis is to ensure a consistent food supply, especially during periods of scarcity, such as winter or breeding seasons when food demands are high. It allows birds to overcome immediate hunger and save resources for times when foraging might be difficult. This behavior also plays a role in the social dynamics of some corvid species, as individuals may defend their caches from rivals or even raid the caches of others. Understanding kolipázis contributes to our knowledge of avian foraging strategies and the ecological adaptations of these intelligent birds.
