What type of habitat do eyasses typically depend upon?

Eyasses, which are young raptors, primarily depend on nesting sites as their habitat during the initial phases of their development. These locations offer the critical shelter and security that young birds require while they are still reliant on their parents for food and care. Nesting sites provide not only a safe environment for growth but also access to food that adults bring back from their hunting excursions. During this early stage, eyasses are not equipped to hunt independently and remain in the nest until they develop the necessary skills and strength.

The other options do not accurately reflect the primary needs of eyasses. Urban environments are not specifically suited for young raptors, especially since they need safe places to nest and grow away from potential dangers and distractions prevalent in city settings. The ability to hunt independently pertains to older raptors that have left the nest and developed their skills. Lastly, while open fields may provide hunting grounds for adult raptors, they do not serve as nesting habitats, which are critical for eyasses during their early life stages.
