GULL CULL REPORT 2002 - 2003
GONHS Gull Control Unit
The yellow-legged gull Larus michahellis is considered a pest in Gibraltar. Not recorded by Howard Irby in his Ornithology of the Straits of Gibraltar published in 1897, it had become numerous enough for the Royal Air Force to commence gull culling activities in the late 1970s, mainly by destroying eggs, nests and chicks. These activities were subsequently taken over (still under R.A.F. supervision) by the Gibraltar Regiment and the private contractor SERCO International. SERCO's Bird Control Unit continues to be active in the airfield area. In previous years the Armed Forces carried out destruction of gull nests throughout the Rock. However, since 2000 there has been no significant contribution to gull culling by Forces personnel or contractors other than on the airfield.
In July 1997, the Gibraltar Ornithological & Natural History Society (GONHS) was engaged by the Gibraltar Government Ministry for the Environment to cull gulls.

LITTLE BAY CLIFF
Environmental Survey
October 2002
This survey has been conducted in a hurry. The failure of the Government of Gibraltar and of Golder Associates to properly consider the environmental aspects of cliff stabilisation works at Little Bay prior to the allocating of the tender for the works resulted in a complaint being made to Government pointing out the need for an assessment. The Technical Services Department agreed that such a survey should take place but placed a time limit of 22 October, a total of three weeks.
GONHS, through its Cave & Cliffs Section, organised a survey of the cliff, which included inspection and photography. The survey has been quick but thorough, and there has been little time to properly digest and assess the results or to prepare a thorough report. This, therefore, is a brief summary of results and recommendations .
