September in Andalusia, raptors across the Strait of Gibraltar, flocks of Greater Flamingoes and other waterbirds on the saltpans, a fantastic array of traditional resident species across the region. However, for me, the main focus of this four-day trip was the search for several late season butterflies, most specifically Two-tailed Pasha, Geranium Bronze and the highly localised Desert Orange Tip and Zeller's Skipper.

Despite September being way past the peak butterfly season, I did still manage to see a total of 22 species, including all my targets, plus some additional bonuses such as European Chameleon and a good range of birds, including impressive raptor movements and some highly desirable species such as Rüppell's Vulture, Long-legged Buzzard and Bald Ibis.

Primarily a short trip to Catalonia to search for Spanish Festoons, Nettle-tree Butterflies and other early season butterflies, the trip evolved a little to include a detour to seek Dupont's Lark, one of the last of Europe's regular breeding birds that I had yet to see. With this in mind, traveling from 7-14 April 2017, the basic itinerary was a day on the Belchite Steppes for the Dupont's Lark, then a day in the Ebro Delta, then the remainder of the week in northern Catalonia, looking for the target butterflies.
