24 Apr: Overcast skies with a moderate easterly becoming lighter in the afternoon. Normally raptors are not recorded from the Rock, during spells of easterly winds. But after several days of gale force easterlies, the number of raptors accumulating on the African side of the Strait, unable to cross in these strong winds, must have been incredible.
