On September 19, our last two young Ospreys of the 2015 reintroduction season left for Africa. The project team were watching PP1 and PP4 (named after the code on their colour ring) when the female suddenly spiralled high into the sky before heading south. A few hours later PP4 did the same. The photo above shows the difference in size between PP1, the female (to the left), and PP4, the male, on top of their release aviary. Since September 19 we waited several days to be absolutely sure that they had really left. It is common that young ospreys first make a “false departure”, which might last up to 2 or 3 days, before returning to the reintroduction site for more food before they finally decide to set off. Now that we are sure that PP1 and PP4 have really left we wish them a safe journey, hoping that they will avoid the numerous risks that all Ospreys face from the moment they are born.
