I found your site while searching for help with my 6 y/o parakeet. it seems to be a female. Once a year it regurgitates food onto its perch and then gets it on her face , its reddish brown stuff that dries up on the perch and then he bird picks at it. She doesn't seam to mind it on her face. but when it covers her nostril is when i worry. what's going on? Thanks for the help, and welcome!
