Committee members, Stefan and Els have been considering the issue of species seen in winter which we would normally expect to be summer migrants on the Costa Blanca, and whether we should collect information about them. They have identified five relevant species namely – Cory’s Shearwater, Squacco Heron, Little Bittern, Quail and Scops Owl. Malcolm and Barry have added House Martin, Barn Swallow, Whiskered Tern and Night Heron to the list.
An issue arises when someone sees one of these species in the spring, and it is not clear whether the bird should be included on the Spring Migration List or not, as the bird may have been here all winter. This confusion could mean that we do not collect information about either the bird’s spring arrival time, or about sightings of the species during the winter.
These considerations have been discussed by the Committee and members were also invited to comment, leading to the conclusion that we should add a new page to the Reports section of the website to record sightings of the above mentioned species on a new Winter Sightings Report. We would therefore invite and encourage CBBC members and other local and visiting birders to report any sightings of these species during the months of December, January and February to be recorded in this report.
Relevant months – December, January and February
Species – Cory’s Shearwater, Squacco Heron, Little Bittern, Quail, Scops Owl, House Martin, Barn Swallow, Whiskered Tern and Night Heron
