Seems as if the Bonaparte's Gull has departed. Only 2 Black-headed Gulls on the estuary this morning in contrast to the 6-7 that have been associating with the Bonaparte's Gull in recent days. Other birds included at least 6 singing Cetti's Warblers, 2 Whimbrel north up the estuary and 4+ Sandwich Terns off the seafront. However, whilst scanning the sea, a distant Glaucous Gull sat off-shore was a nice bonus as it slowly followed a small fishing boat. Unbelievably, it followed the boat all the way in to Budleigh beach allowing very close views of this 2nd winter bird. Best viewable from western side of seafront around hauled up fishing boats.
