I know of a few spots, but even then it requires patience and some luck in catching them in flight. This is the main give away for me. Lots of other birds will flit about and dart across, or even hang up under the leaves. The Spotted Flycatcher though will often take a perch and then swoop up or out to catch a fly before returning to the same branch.
I searched in vain for an hour or so last Saturday night, but then returned to the same spot on Sunday morning and found one within minutes. I knew I was in the right spot, just needed to bide my time. Unfortunately now, the trees are in full leaf in most parts and so photographing these lovely birds is a bit trickier. Despite not many pictures, I enjoyed watching this particular bird for some time. I hope it won't be my last of the year.
