² tn There is debate in the commentaries and lexicons about the identification of some of these birds, particularly regarding the identification of the “swallow,” which is more likely the “swift,” and the “crane,” which some identify with the “thrush.” For a discussion see the Bible encyclopedias and the UBS handbook Fauna and Flora of the Bible. The identity of the individual birds makes little difference to the point being made, and “swallow” is more easily identifiable to the average reader than “swift.”
