While time outside a cage can be a positive experience your bird, it can also be dangerous, especially for small birds that can be easily stepped on or injured in falls. Birds also do not understand the nature of glass windows or mirrors. Like wild birds that fly into windows from the outside, pet birds can be injured flying into these barriers. Birds outside their cages should be carefully monitored to ensure they cannot escape and to avoid accidents and injury. All windows and doors in the area should be fully closed before you release your bird from its cage.
Other hazards for birds outside their cages include access to toxic materials (including certain house plants and dangerous foods and medicines), electrical cords, stove tops, open toilets, and other seemingly innocent household objects (see Common Household Poisons). Birds have been caught in blankets, trapped in clothes dryers, drowned in sinks and toilets and even sucked into vacuum cleaners. Be sure to monitor your bird any time it is outside its cage.
