What is a common frustration when taking an eyass from the nest?

When taking an eyass from the nest, a common frustration arises from climbing the tree only to find one eyass present. This situation can be disappointing because falconers often aim to select a young bird that has siblings, as this can aid in socialization and development. Having only one eyass not only limits the potential choices for the falconer but may also indicate that the nest did not thrive as well as others. Furthermore, an eyass raised with siblings typically benefits from the competition and learning experiences that come from interacting with its nest mates. Thus, encountering just one eyass can lead to concerns about the bird's vigor or viability in training and adapting to captivity.
