 Blue parrots are very numerous there , as well as other birds ; among which are a kind , conspicuous for their size , larger than our swans , with huge heads only half covered with skin as if clothed with a hood . These birds lack wings , in the place of which 3 or 4 blackish feathers protrude . The tail consists of a few soft incurved feathers , which are ash coloured . These we used to call ' Walghvogel ' , for the reason that the longer and oftener they were cooked , the less soft and more insipid eating they became . Nevertheless their belly and breast were of a pleasant flavour and easily masticated .
