Parakeets need a varied but balanced diet and plenty of water. Dehydration can kill your bird quickly, so always make sure there's water in her cage. Instead of buying a standard bird seed, look for a seed mix that is designed specifically for parakeets. These often contain dried fruit and other nutrition your bird needs, such as calcium -- low blood calcium can cause sudden death. Give her some small pieces of fresh, raw fruits and vegetables to help round out her diet. Don't leave fruit in her cage all the time, though.
Birds usually reach the ground before they die, and because they know that they are vulnerable on the ground they hide. The bird is sometimes carried off by a weasel, stoat, or cat, but more usually they just die and the carcass is soon disposed of by crows, magpies, seagulls, or maggots.ost humans, at least in the developed world, live long enough to have children. Birds also tend somewhat towards the âKâ end but not so far as humans. Passerines in particular (which include most common garden birds) produce large numbers of offspring, the majority of which do not suvive to adulthood.
