All pet birds benefit from weekly exposure to fresh air and sunshine. Many pet bird owners take advantage of the approaching warmer weather of springtime to allow their caged birds to enjoy an outside sunbathe. This is a great idea, as long as the birds in cages are not left unattended, There are many predatory birds in the great outdoors such as currawongs, magpies, crows and goshawks. In the springtime breeding season, these predators are more dangerous than at other times of the year. In common with all wild birds, the predatory birds are raising their chicks and looking for food to sustain their hungry broods.
Smaller pet birds in cages hanging outside on balconies, verandas or patios are like hors d oeuvres for the predators. When a predatory bird swoops on an unattended cage, housing a small bird, there is no protection or shelter for the pet. Terrorised, they flap uncontrollably about the cage to escape the predator. As their wings, feet or head touch the bars; the predator grabs with its beak or talons and pulls at their prey. The birds most at risk from predator attacks are the smaller pets (budgies, canaries, finches, love birds and cockatiels).
I am often presented with birds suffering injuries of varying degrees of severity from these attacks. Some victims suffer nothing more than minor abrasions. Others have eye injuries or are scalped. Many have dislocated or broken legs and wings. Some have wings that are degloved (the skin torn from the muscle). In very severe cases, birds have been decapitated or had their wings torn from their bodies. We must remember it is not the predators fault; they are doing what comes naturally i.e. taking advantage of an easy meal for their offspring. It is the pet bird owners responsibility to take steps to protect their pets from predators. That is why I am constantly reminding my clients not to leave their smaller caged birds outside, unattended. Birds in aviaries are less likely to suffer from attacks as there is more room within an aviary to escape from the predators.
Spring and summer are also the times when reptiles are active. Hungry carpet pythons and brown tree snakes pose another danger to caged birds left outside, unattended. Even larger birds such as galahs and cockatoos can be preyed upon by larger carpet pythons. Birds in aviaries are not immune from predation by snakes. It is necessary to make your aviary snake proof i.e. blocking up any areas that could enable a snake to enter the aviary.
By all means allow caged birds to enjoy some fresh air and sunshine but take care to protect them from the predators that exist naturally in the wild.
