These small outdoor structures are critical for our smallest patients, including insectivorous birds with a high metabolism as well as mammals such as a squirrel, marmot, or mink, for pre-release conditioning. The avian screen house was upgraded in 2018 with a concrete floor and wire screening to ensure it is predator proof. Both enclosures require annual maintenance including a deep clean, replacement of gravel, and repairs to screening, nest boxes, and other enrichment materials.

Annual sponsorship will support annual maintenance costs and supporters will have their name or that of an honouree displayed on the enclosure for one year as well as receive a certificate displaying their support.
