Down to the park for 0600 this morning to try to catch up with a Ruff (found by Keith Edwards on Monday). I'd tried after work on Monday but glare and poor optics defeated me. 2 Foxes seen and 2 Tawny Owls heard en route. Found a single Ruff as tide came in, then 2 together when it receded. Met up with Keith after a spot of vis-migging (visible migration) which had produced Tree Pipits, Meadow Pipits, Chaffinches, Siskins, Pied Wagtails and Grey Wagtails, and Swallows as well as an Osprey. Detoured into the 'bowl' north of the composting toilet as Keith headed homewards and Keith's sharp eyes spotted a new park-tick for us both - a Spotted Flycatcher (only the second sighting - one previous sighting in September 2012). I ended up staying at the park until 1400 and managed to rack up a new record day count for the site of 66 species of bird - though if I'd been able to hang around longer (and walk even more) I suspect I might've caught up with some of the 'missing species' including Dunlin and Coal Tit (possibly also Little Egret - 2 seen together on Saturday, and Little Grebe - sporadic sightings over past month or so) to get a total closer to 70. I might try again on Sunday, weather permitting, as late August seems to be the best time for getting a lengthy list (previous best was 63 on August 31st 2014). Other highlights today included Turnstone, Knot, lots of juvenile Blackcaps, Great Spotted Woodpecker, Goosander, Guillemot, 6 Osprey sightings, Sand Martin, Swift and a Wheatear, as well as a showy Speckled Wood butterfly in exactly the same spot as my previous sightings of the species at the park this year.
