When they fly low over scrub now and again, they appear extremely dark. The males perform their skipping and dancing song flight especially in the morning. Their song activity is considerably reduced in spring compared to migrating warblers – presumably due to the Dartford Warbler pairs being faithful to their habitat and having already claimed their territory in autumn.
