Common Swift (Apus apus) Vencejo común
The scientific name means 'without feet' and is eminently appropriate for a species that lives, sleeps and even mates on the wing. It nests in eaves and roof spaces of older buildings in cities and towns across Europe. It generally arrives in Ireland in early May and the vast bulk leave in August for Africa - making it one of the shortest staying migrants we have. Juveniles, such as the bird in this photo, are not often well observed in Ireland as they appear to depart soon after fledging. This bird was photographed in Fuerteventura.
