Sherrie K. Henne, Webmaster

Sherrie bred and showed parrots for eight years in New Orleans, LA and in Dover, FL. She also volunteered at the Baton Rouge Zoo in the docent program and at a no kill animal shelter there. After retiring from aviculture, she still wanted to give something back to the avian community so in 1998 she began building this website. The site has definitely grown since its beginning and continues to be one of her favorite projects. She is a full time web designer and webmaster, with one of her specialties being sites that are animal oriented. If you are interested in hiring a web designer, you can find more information at
