The whole business of rescuing birds is both wonderful and sad. It is wonderful that unwanted, perhaps mistreated and abused birds can find a new home. It is sad that the whole problem arises in the first place. Some people have even gone so far as to suggest that people stop breeding birds until homes can be found for all the birds in need.

The blue and gold Macaw in the photo is "Blue". Blue found himself at Chihuahuan Desert Wildlife Rescue after the owner who had kept him for 12 years passed away. (Look for his story and others in their animal casebook).
