Although it is not a bird that many people see very often, the common crossbill (Loxia curvirostra) is quite common in the UK and has probably increased in numbers as a result of the planting of pine forests. It is a very distinctive bird, sometimes called the ‘parrot of the northern woods’. As its name suggests, the tips of the bill cross, enabling the birds to extract seeds from pine cones, their principle food, and giving the birds a rather parrot-like appearance. Males and females are noticeably different in colouration. Males are a rich brick-red on the head, back, rump, and belly. The wings and tail are a dark brownish-grey on both sexes, but females are grey-green where the males are red. The head of the bird is disproportionately large, with a thick ‘bull’ neck, and the tail is forked. Common crossbills call frequently whilst moving about in the trees, making a high-pitched, metallic sound like ‘glipp-glipp’. The song is a series of trills and twitters.

 

There is an old belief that the common crossbill acquired its peculiar beak as a result of trying to remove the nails from the hands and feet of Christ when he was on the cross. This incident also accounted for the male bird’s red breast, a story which is also associated with other red-breasted birds such as the robin and goldfinch.
