Scientist in Winter
One of the resident scientists came outside with some of her study birds and told us a great deal about Crossbills. More than I can remember.
One thing I do remember is that the bills are not all crossed the same way. Some cross the upper beak over to the right of the lower and others to the left. This is not something that is apparent at birth but develops as the bird grows. It is more complicated than that but that is the basics of it.
