The first week of April a Birdlife Malta team went to Filfla to make the annual Yellow legged gull (Larus michahellis) census. Filfla is the more important site breeding site in the Maltese islands for Yellow legged gull. Since 1982 Filfla has been visited yearly to monitor the Yellow legged gull’s colony.
The team reached the plateau of the island in a helicopter provided by AFM (Armed Forces of Malta). Gull nests were mapped with GPS on the plateau and regurgitates samples were collected.
Nest are found all around the plateau on the ground. In general every nest has two or three eggs. At this time of the season the majority of gulls are incubating the eggs in the nest. But some eggs were already hatched and some small chicks can be seen.
Late in the season Birdlife team will come back to Filfla plateau to count and ring the Yellow legged gull chicks. Then we will know how many eggs hatched successfully.
