It's important to create a safe environment for first clumsy flight attempts. Always keep your fledging baby close to the ground. He should only be as high as the couch or coffee table. Put away breakables that could be damaged in less-than-perfect landings. Close the drapes so your bird will be cushioned in case of collision. Make sure doors and windows are closed. Beware of other pets in the house. Even the slightest injury from a cat or dog can mean death within hours for a bird, due to bacterial infection.
