I looked for these for at least two hours and then got lucky. Two appeared in front of me and perched, as if they came from nowhere, stayed just long enough for a photo, then flew away quickly and were not seen again. Right place, right time, mega lucky.
Heavilly cropped photos, not the best images, but a new one for me and a new one for NatureShare. I only had very distant views. I was lucky to see them as they didn't call at all and I only saw them because I saw something move from the corner of my eye.
