Whilst birding the Waste Water Lake in the very early morning, I located eleven Ferruginous Duck an increase from the seven seen recently. The birds were sitting on the lake and hiding in the reeds but were disturbed by two Western Marsh Harriers hunting and flew around a little before settling again on the lake. This allowed me to take a few photos in flight as they circled deciding if it was safe to land back on the water. Four of these birds have been around for almost two months with the others joining over the last couple of weeks.
