An immature Great Black-backed Gull near the Bou Regreg estuary at Rabat, 25 February. Other interesting gulls were a Common Gull and also a Slender-billed Gull, a species which is rarely seen around there.
Other interesting sightings were three Marbled Teal at the marshes, a Moroccan Wagtail (another taxon I hardly see here) and a flock of Spoonbills migrating north (Pedro Fernandes)
