IN order to try to encourage the iconic Osprey (or Fish Eagle) back to Gibraltar, the Department of the Environment, Heritage and Climate change (DEHCC) has begun installing artificial nests within the Gibraltar Nature Reserve.
Ospreys were known to nest on Gibraltar’s steep eastside cliffs up until the 1930s when the last breeding pair was recorded. Population numbers declined throughout much of Western Europe during this time largely due to the collection of eggs, hunting and habitat destruction and in Gibraltar, it is likely that quarrying and military activity during the war years also contributed to its disappearance.
In the region, a few pairs of Ospreys remained nesting on inaccessible sea cliffs on the coast of north-eastern Morocco but over the last decade the Osprey population has increased in many places around Europe including Scotland, Germany and Scandinavia.
A reintroduction programme is currently underway in Cadiz and scientists from the Department of the Environment have recently joined the regional efforts to increase population numbers in consultation with the Gibraltar Ornithological and Natural History Society as well regional experts from Andalucia.
Partly as a result of the reintroductions in Cadiz, where some pairs are now nesting, Ospreys are now found all year round in the Bay of Gibraltar and are regularly seen on migration in Spring when arriving from their wintering grounds in Sub-Saharan Africa.
The installation of artificial nests with decoys is aimed at attracting the interest of passing Ospreys that may then be enticed to stay.
