Anatomy and function
The upper respiratory system (URS) consists of the external nares, operculum, nasal concha, infraorbital sinus, and choanal slit.
The nares are paired symmetrical openings with an operculum within each. The nares each communicate with the nasal cavity containing the concha.
The left and right nasal cavities are separated by a septum. The nasal cavity communicates with the left and right infraorbital sinus.

I have a 5 yr old Catalina Macaw that I have had since he was 6-1/2 weeks old. At 6 months old, he broke the bars of his first cage, then we got him a big “Kings Corner” Cage, and it didn’t take him long to learn how to open the latch on the door, so we have been duct-taping that for quite some time now.
