Unusual number of Glaucus gull and Iceland gull

Glaucus gull (Larus hyperboreus) and Iceland gull (Laurus glaucoides) were observed in Portuguese coast in an uncommon number. Normally we only see one or two individuals of this species, but this winter, were registered 7/8 of each specie.
There’s still no scientific explanation for this behaviour.
