Twitching was not a common term in the early 80’s, but some surveys like autumn raptors migration in Kafer Kasem fields, or spring migration survey in Eilat (photo above with Hadoram Shirihai & Yaron Baser) along with other trips through out the country, contributed some good bird families to the list.  Bearded Reedling and Wallcreeper are worth mentioned as they are half of the 4 Palearctic endemic (monotype) families.
