Gannet migration frenzy

Last night I picked up severeal lines of adult Gannets going west past Europa Point, heading out for the Atlantic. It was a clear signal that migration of these birds had intensified. The passage continues today with small groups flying out in lines. Most are adults which is what you would expect in February. Adults will continue to dominate the passage into April. After that, first, second and third years will become more abundant. The extent of Gannet migration is strongly dependent on age, the youngest birds flying furthest away from the breeding colonies, many staying in the winter areas through the summer. Many of the Gannets were getting attracted to an upwelling off Europa Point this morning, pausing to have a snack before continuing. Here are some photos from today. Notice how some Gannets have fishing lines trailing.
