The California condors seem to have changed their diet habits. Though now, they are fond of dead deer, cattle and other animals, carcasses of marine animals once formed a large part of their diet. To add to it, some condors are already finding food in sea lion and seal rookeries that have been growing along the West Coast, the Stanford University researcher Page Chamberlain reports. As a natural food source, conservationists provided dead animals, especially the marine mammals to the condors as a large part of their diet. The birds like to stick to the diet, once they like it. Though they eat whatever they can find, they will continue to fly over the area looking for more once they find a source of food. So, to help reintroduce them to the seals and sea lions some young condors are being raised in pens near the marine mammals breeding ground. ‘When these are released they know of this source of food and others will follow them there’, Chamberlain, a professor of environmental science said.
