[Martin Scott]

hybrid with what parentage?

[Joe Ray]

hybrid with what parentage?
Presumably arctica x pacifica?

Are there any photos of the bird, it was promoted from a possible to a definite by the information services some time ago, I don't know if this was due to photos, or simply better views of the bird allowing more features to be seen.

Does anyone know why a hybrid has now been suggested, and what features on this individual are different to those found on 'standard' pacifica?

Birdguides are reporting it as "aberrant Great Northern or hybrid", so presumably the speculation is immer × arctica, rather than pacifica × arctica.

[Martin Scott]

Apparently it is a Great Northern.
