English & Spanish Bird Check List
There are many sites on the Internet that give mixed language lists of our European birds. Some of these may be found under LINKS (page 9).
However, if visiting Spain and you are able to make contact with one of the local Bird Groups affiliated to or part of the Spanish Ornithological Society (SEO), then try and obtain a copy of their little handbook which includes the full Spanish list with the corresponding Latin and English name. The price may vary depending upon whether you are purchasing at source or from a fund-raising affiliate. Either way, it will cost no more the 2 € and has 5 columns that can be used as a check list.
