We saw 2 Great Spotted Woodpeckers this morning, both adult males I think, given the red spot on back of their heads. Over the course of a short 5mins watching them we saw these two interact - sometimes it seemed like they were trying to ignore each other by turning their backs and looking away from each other, at other times they looked directly at each other. We saw them chase each other - they started in a scrub patch/tree next to a hedge (too thin to use as a nest, I would think), then onto a telephone pole and finally perching on the telephone wire above the pole. After 5mins they flew off in different directions - one back to the original scrub/tree we found them in and the other went in the other direction. Is this usual territorial behaviour? If anyone knows where I can read more about this would be appreciated, thanks in advance if you do.
