Report information
12th March
Logie has started her migration!! She roosted overnight on her usual tree; at 10 am she was perched 500 metres to the south on one of her normal daytime roosts, then back at main roost at 11am. Maybe she had caught and eaten a morning fish, because at midday she was 4 kilometres to the north, very close to her position of 10th, but this time she was flying NNE, at 50 km/h at an altitude of 258 metres. She was off!
An hour later she was flying NNE at 57km/h low over the sea to Bolama Island; at 2pm she was crossing from Bolama to mainland Guinea Bissau 53 kilometres from her winter quarters. She was circling and gaining height to 233 metres. Two hours later she had crossed the wide estuary of River Corubal, about 40 kilometres upstream from the capital, Bissau. By now she was flying over woodlands and villages at 564 metres altitude.
At 5 pm, she had covered another 47 kilometres NNE and was flying at 47 km/h in a NE direction at 900 metres. Half an hour later she crossed into SENEGAL and was just north of Lengueto. Her speed was recorded as 80 km/h, heading NNE, but she was probably descending fast towards woodlands 10 kilometres further north where she roosted for the night by 7pm.
The first leg of her great migration was 221 kilometres and she flew for just over 6 hours at an average of 36 km/h. The weather was ideal for starting her migration; clear conditions, rising pressure and light winds 16 km/h from the west. The temperature up to 79F.
