Select a collar that approximates the bird's head size or slightly larger.  Several sizes may fit. Choosing the best one for the restraint intended is key to achieving effectiveness while maximizing comfort. Avoid maximum extension of a bird's neck.  This could result in discomfort, pressure sores, or circulatory compromise to the head.

The collar size increases in 0.2 inch increments.  Sight variations in a bird's conformation and size  will result in different degrees of effectiveness.

Always check for any injection molding imperfections that occassionly occur during production. Smooth any burrs off surfaces that contact the patient using a dremel or similar sanding tool.

Any collars that close with difficulty should be examined for extra plastic in the joints. This, too, may be dremeled off to enable easier closer.

'Three step’ Process of Applying the Collar: 

First, align the numerically marked side of each hemisphere to the inside of the opposing hemisphere's unmarked side.

Second, rotate back and forth to release any feathers.

Third, place finger pressure on each protruding unmarked rim. Press to lock. Do not apply a constant, increasing force. The collar is designed to lock easily. Recheck alignment of the two halves or try shifting pressure points slightly. After locking, verify the collar turns freely.

Helpful Tip: When fitting smaller collars, place a temporary mark at each numerical site. This will help to more easily identify correct alignment while placing on the patient.

Cautions:                                                                                             

• Due to the unique locking mechanism, always instruct owners on how to remove the collar should the need arise. Let each client put a collar together and take it apart until a clear understanding is achieved.
• Always examine each collar before applying to verify smooth surfaces and ease of use.  Due to slight variations the injection molding process, some collars may initially require more pressure to lock and unlock. It is appropriate to determine this before trying to apply on a patient.   
• The collar may affect the balance of weak patients or birds with leg injuries. Routinely monitor all birds wearing a collar.                         Never take this or any restraint collar for granted.
