Yes, welcome to Birdforum.
Fernhill Heath is just a stone's throw from Porter's Mill / Tapenhall area.
During passage periods, this area can produce Whinchat, Wheatear, Tree pipit, Redstart, Spotted Flycatcher, Stonechat and Yellow Wagtail. There is a good selection of breeding warblers and, in a good year, Grasshopper Warbler may be present. Little Egret are quite frequent and occasional species include Red Kite, Lapwing, Common Tern, Oystercatcher, Common Sandpiper, Curlew and, exceptionally, Osprey and Merlin.
Mandarin Ducks are sometimes found in this area as well as Little Grebes and Little Owls are often present (bred successfully last year). Kingfishers and Grey Wagtails are frequent along the canal and river.
Many of the usual farmland species are present - Yellowhammer, Skylark etc. and Meadow Pipits outside the breeding season.
In late August 2004, a Wryneck was present in a garden at Dane's Green, Claines, for a few days.
All the best and good birding.
