Alpine Swift I saw a lot of these all over Barcelona
Audouin's Gull I only saw a couple of these
The Audouin's Gull is a large gull restricted to the Mediterranean and the western coast of Saharan Africa. It breeds on small islands colonially or alone, laying 2-3 eggs on a ground nest.
In the late 1960s, this was one of the World's rarest gulls, with a population of only 1,000 pairs. It has established new colonies, but remains rare with a population of about 10,000 pairs.
This species, unlike many large gulls, rarely scavenges, but is a specialist fish eater, and is therefore strictly coastal and pelagic. This bird will feed at night, often well out to sea, but also slowly patrols close into beaches, occasionally dangling its legs to increase drag.
This was the only Hoopoe I saw
These were all over the city
Spanish Wagtail ?
Yellow Legged Gull's
I have just returned from 5 days in Barcelona on a city break I managed to get some bird photos on the last couple of days
