very common
It is the most abundant bird of prey in the lake. It is common to see it gliding on the reedbed. When flying, its characteristic silhouette shows as a “V”.
Due to the desiccation of wetlands such as the lake and many others throughout the peninsula in the mid-twentieth century, and the systematic hunting of ‘alimañas’ (feristeles, in Catalan), the harpoons became a difficult bird to see. Today, happily, their population is in good health again.
