Eurasian bittern
In the 'Birds of Ayrshire and Wigton' of 1869, the Eurasian bittern ("Botaurus stellaris") is recorded to have once bred at Bruntwood Loch. The 1861 OS Gazetteer refers to it as a "quondam loch", meaning former loch, having once been much frequented by waterfowl, but now completely under the plough.
