Northerly airflow affected all air traffic

Whilst in Donegal I found this Brent Goose. It appeared exhausted and poor physical condition, barely moving for holiday makers.

I first found it on Sunday and apart from looking thin it appeared in reasonable health and feeding well, and flying freely around the headland. By Monday morning however an eye infection was having severe impact on the vision of the bird.

I wonder if the same airflows that have brought volcanic ash misery to thousands of human travellers have caused this bird to turnback on it's trip north towards Iceland. There were still many Whimbrel in both Donegal and Ballycastle all waiting for more favourable weather conditions.
