What structural feature must an indoor raptor facility have for ventilation?

An indoor raptor facility must incorporate structural features that ensure adequate ventilation to maintain a safe and healthy environment for the birds. The choice emphasizing the necessity of at least one window secured with vertical bars highlights the importance of a physical opening that allows for airflow while safeguarding the raptors. This design helps to facilitate the exchange of fresh air and prevents the buildup of stale air and harmful gases, which can be detrimental to the health of the birds.

In addition to security provided by the vertical bars, this feature allows natural ventilation, promoting a comfortable and appropriate temperature within the facility. The design prevents the escape of birds while still permitting air movement, which is crucial for the well-being of raptors that require proper air quality.

Other options, while they address ventilation in various manners, do not encapsulate the dual needs of security and airflow as effectively. An open roof design may provide some ventilation but lacks controllability and safety. Multiple vents at ground level could facilitate airflow, yet they might not be as efficient in promoting sufficient ventilation compared to higher openings. An air conditioning system can regulate temperature but is not a natural solution for air exchange and may not function in an optimal manner without additional windows. Thus, the choice of a window secured with vertical bars addresses both the need
