Having done three big days in mid-May, I've thought for a while that I could potentially beat my record total of 81 species in late summer, when most of the summer visitors are still around and there's more potential for migrants, waders and seabirds. So today, I had my first try at beating it. I was out the house by around 5.45 and started off at St Fittick's. A useful thing I learned is that it's probably not worth bothering with at dawn at this time of year, as nothing much was singing and very few birds were active. I did get Goldcrest on the list though.
I headed off round the headland, where I spent the next few hours, mostly moving between the foghorn, Greyhope Bay and the Battery. Two Stonechats were again seen on the south side of the golf course. Seawatching was fairly slow, although I did get two Puffins, a juvenile Black Guillemot, a few Common Scoters and a flock of seven Teal. Four Harbour Porpoises surfaced in the calm waters. Waders were also pretty ordinary, with three Knot and four Dunlin the best of it. Otherwise, there was a steady accumulation of birds, with highlights being a Peregrine picked out on a city centre building and two Swifts over Torry. A flock of 12 Tree Sparrows briefly landed in the bushes at the Battery, a Wheatear was in Greyhope Bay and a Siskin was heard calling as it flew over.
I spent that late morning looking carefully looking around St Fittick's, trying to dig out the passerines that were no doubt lurking there. A pleasing surprise was a Pied Flycatcher, which appeared in the trees at the northeast end of the park. Otherwise, I was able to find potentially tricky birds like Long-tailed Tit, Coal Tit and Bullfinch. A Stock Dove flew over Tullos Hill. It was also lively for butterflies, including very large numbers of Red Admirals and a few Speckled Woods. The latter species seems well established here these days. I also saw my first Odonata of the year, with an Emerald Damselfly and a Common Darter. I walked over to the River Dee early in the afternoon, but Buzzard was the only notable addition there. Several Guillemots were along the river, right up to the railway bridge.
I had a rest through the middle of the afternoon with the total on 72 species. There were plenty of possible things to look for but I reckoned the best bet was to go to the foghorn to seawatch. A pair of Collared Doves on Victoria Road and a Whitethroat at the Battery took the total to 74. Seawatching in the calm conditions and light onshore winds was quite good, although the light was sometimes awkward. Three Arctic Skuas and a Bonxie took me up to 76. A Ruff flew south with other waders to make it 77. Two Sooty Shearwaters went north, with one fairly close in, and a Whimbrel went south. That was 79 and species number 80 came with a line of 35 Canada Geese heading north over the sea. That was about it though, so one short of the record.
I think it should be easy enough to get well over 80 in late summer, particularly if it's a good day for migration. I suspect the total could be beaten at any time between late July and mid-September, so there's a fairly long window of opportunity too.
