        FINCHES

           HERE ARE TWO MAIN groups of finches, the
        TFringilla species (Chaffinch and Brambling)
        and the Cardueline finches.The Chaffinch
        and Brambling are clearly closely related, their
        different colours arranged in very similar patterns;
        they have the same basic shape and behaviour,
        and frequently mingle in winter.
         The others, however, are a very diverse group.
        Their shapes and behaviour are strongly
        determined by their food.The crossbills have

                                                     Crossbills eat an abundance of dry seeds and
                                                     must frequently pause to drink from a puddle
                                                     before flying off to another conifer.
