Having been to Spain now at different times of the year I still would find it helpful to have a phenology of birds in Spain at hand. Especially late in summer it is hard to judge whether it is worth the effort to look for a specific species which might already have returned to its wintering grounds.
Is some information on the phenology available (preferrably accessible in electronic form)?
Cheers,
Matthias
