This species is native to the western Mediterranean Basin in Europe (Iberia, southern France, Italy, Monaco) and North Africa (Algeria, Morocco, Tunisia). It is common in much of its range.

9-8-2020 GANDIA PUERTO, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)
Not really a black-headed bird, the Black-headed Gull's head is more chocolate-brown. In fact, for much of the year, it has a white head. It's most commonly found almost anywhere inland. Black-headed Gulls are sociable, quarrelsome, noisy birds, usually seen in small groups or flocks, often gathering into larger parties where there is plenty of food, or when they are roosting.
Spring and summer days are full of squawking and squabbling for Black-headed Gulls. These dainty gulls nest in tightly packed colonies, where safety in numbers gives the best chance for their chicks’ survival. Like other members of their family, Black-headed Gulls are adaptable, and these colonies are as at home on our coastlines as they are in our towns. Large groups of birds are often seen following tractors on our farmland, too.

27-10-2017 ADOR, VALENCIA - MEADOWHAWK DRAGONFLY (Genus Sympetrum)
Sympetrum is a genus of small to medium-sized skimmer dragonflies, known as darters in the UK and as meadowhawks in North America. The more than 50 species predominantly live in the temperate zone of the Northern Hemisphere; no Sympetrum species is native to Australia.
Most North American darters fly in late summer and autumn, breeding in ponds and foraging over meadows. Commonly, they are yellow-gold as juveniles, with mature males and some females becoming bright red on part or all of their bodies. An exception to this color scheme is the black darter (Sympetrum danae).
