At our last meeting we ventured back in time to the last Ice Age, when the Bay was scoured out from the underlying rock by glaciers making their way down from the Scottish Highlands and the peaks of the Lake District. Since then the Bay has been filled with fine silts to a depth of 80m in places, leaving a shallow, productive, estuarine environment. The plants at the bottom of the food-chain in the Bay are microscopic unicellular algae called ‘phytoplankton’, and their lives are governed by the tides and river currents, and they are so small that you may have overlooked them, even though massive numbers of them live in the Bay…
On the 9th December we will turn our attention to two, more visible, groups of wildlife that use the Bay – the fish and the birds. These animals use the winds and the tides, and are able to hunt and explore as they see fit. Among the bird life of the Bay you may spot Percy the peregrine falcon. If you’re lucky you’ll see him doing a ‘fly-past’ over the bay during the autumn and winter and causing a commotion!
