What do the terms 'passage,' 'imprint,' and 'chamber' describe?

The terms 'passage,' 'imprint,' and 'chamber' are specifically used in the context of raptor training and falconry to describe the conditions and experiences of how a raptor was raised.

'Passage' refers to a wild bird that has recently fledged and is still in its juvenile stage. These birds are typically caught in the wild during their first migration, and they have not yet been influenced by human interaction, which can affect their behavior and training.

'Imprint' describes a raptor that has been raised in captivity and has developed a strong attachment to humans, often affecting its behavior and how it responds to the falconer. Imprint birds are typically raised from chicks and, as a result, may not have the natural survival instincts that wild birds possess.

'Chamber' relates to a specific housing condition or environment where raptors are kept, often in terms of their physical space, but in the context of this question, it ties into the overall experience of the raptor in its upbringing.

These distinctions are crucial for falconers as they determine the training approaches, handling techniques, and overall management of the birds based on their early life experiences.
