Since arriving in Senegal almost a month ago, 30 has remained faithful to a short section of coastline, midway between Saint Louis and Dakar. It’s just 2km south of where 09(98) used to winter, and like 09, 30 has made only short local flights since arriving. In fact her latest ten days’ of data shows that the furthest she has ventured from her favourite perches is just over one-and-a-half miles! This is easy to understand. The sea provides a rich food supply, and Google Earth suggests that the area is relatively undisturbed; the ideal combination for a wintering Osprey.
As we have come to expect from our satellite tracking studies, most adult Ospreys are extremely sedentary in the winter, and that is certainly the case with 30. She is fishing in the sea once or twice every day, and then perching either on the beach or in a scrubby area less than 100 metres inland. Although the Google Earth imagery for this part of the coast is not of the best definition, I wouldn’t bet against her favourite perches being isolated tress in amongst the scrub.
We’ll continue to report on 30’s progress over the course of the winter. Let’s hope it remains as peaceful as her first month in Senegal.
