Bird species sighted in the marsh and its surrounding

In this section Urdaibai Bird Center publicizes  the  bird species observed in the marshes of Gautegiz Arteaga and its surroundings during the last week. This list will show red colored, those species that we consider remarkable due to its phenology, number, weirdness or other aspects that we consider significant.

As usual, the most important ornithological  sightings  will be shown as  independent news apart from this list.
