Tasmania’s Derwent Valley is notorious for it’s ‘Bridgewater Jerry’ a layer of fog pushed South East by cold air drainage through a series of valley systems towards the city of Hobart. The city, surrounding suburbs and the airports are usually the first victims of this phenomenon. While waiting for the visibility to improve, a group of starlings decided to take flight.
This on a morning where all aircraft from Hobart and Cambridge airports were grounded for a short period until the fog layer lifted allowing the resumption of commercial and private flights.
