The pictures on these pages were taken at the Łubna rubbish dump in May 2003 and 2007. In 2003, I estimated that the most abundant large gulls at the dump at this time of year were Caspian (cachinnans) and Herring (argentatus), followed by Yellow-legged (michahellis). Lesser Black-backed Gulls were uncommon, with just two fuscus and one graellsii/intermedius. In 2007, the situation seemed to have changed. Caspian Gulls still by far were the commonest species, but Yellow-legged definitely outnumbered Herring, as I only saw a couple of the latter (I cannot exclude that more experience may be an important factor here! ;) Lesser Black-backed Gulls were seen in much larger numbers in 2007. I was rather surprised to find quite a few western birds. Mediterranean Gulls were very scarce in 2003 but four years later several birds were present on each visit.
