Ile de Ngor 1 October
Four hours of staring at the sea, hopefully motivating a student who had seen none of her target study species for a month, produced a very short list of the two daily present terns (Sandwich and Royal) and one pomarine skua. I distracted myself for a while by photographing sheep, then noticed a familiar looking butterfly feeding on the cliff top.
It is painted lady, a species found throughout Europe. I had no idea, as quick Google Scholar search revealed, that this species migrates between Europe and West Africa, though in a rather different manner from birds. Migration is staged over several months and several generations. The species breeds throughout the year, adults flying south from Europe in summer , breeding and dying and the next generation continuing the southwards migration.

The defunct, twin volcanoes of Mamelles, in Dakar’s Ouakam arrondissement, with Cape Verde Shearwaters and Bottle-nosed Dolphins. The rocky coast of Dakar, forming the Cap Vert Important Bird Area, is an outstanding site for seabirds (photo: P. Robinson). Technopole and its numerous waders, herons, gulls, terns and other waterbirds (including Greater Flamingos when conditions are right) is one of the best sites for birds in the greater Dakar region (photos: B.
