We have a fabulous field report from our friend and keen osprey watcher Chris Wood who twice in the past week has actually visited the Spanish reservoir (Embalse de Piedras) where Blue YZ has been hanging out.
Chris has seen several osprey around the reservoir – adults and juveniles – and is pretty sure he has seen Blue YZ but has not been able to get a picture of her.
Chris has also solved a mystery for us! Recent satellite tracking data has shown Blue YZ favouring 3 roost spots which are in a very straight line and at a height that seemed rather high for the citrus trees in the area. Chris’s visit to the site revealed that those roost spots are a line of pylons. It shows that although satellite tracking gives us invaluable information, complementing it with site visits (when possible!) gives a clearer, fuller picture.
