There are many carnivorous birds descended from Garuḍa, the winged carrier of Lord Viṣṇu. Indeed, there is a particular type of bird that is very fond of eating monkeys, and eagles are fond of eating goats. Of course, many birds eat only fruits and berries. Therefore the words caram, referring to moving animals, and acaram, referring to grasses, fruits and vegetables, are mentioned in this verse.
