This weekend..
concentrating on the watch point at Ferryhills with yet more impressive movement of Tree Pipits; 81 in 3 hrs on Saturday and 43 in 2.75 hrs on Sunday. Meadow Pipits saw an increase in passage this weekend (peak of 71 on Sat) and there is likely to be a role reversal now as we enter September with the Tree Pipits dropping off and the Mipits taking over.
The highlight  was a Yellow Wagtail flying over on Saturday, a new bird for the Site and an uncommon migrant in Fife. Also of interest was apparent overland migration by Sandwich Tern on Sunday; several flocks totalling 67 birds spiralled up over the Forth and headed high inland. The Forth Estuary holds internationally important numbers of Sarnies in the late summer/ autumn and I've seen birds on many occasions travelling in the opposite direction at dawn from the upper Forth out to the coast having presumably been using a roost site beyond the bridges. However it's more unusual to see them travelling in the other direction early morning so I would say these birds were taking an overland route to the west coast.
I've made more time to look for grounded migrants at Ferryhills following the min-fall last weekend but not much doing, a Wheatear on Sat and a Spotted Flycatcher on Sunday. Probably need some classic conditions with strong easterlies and rain before too many drift migrants make it this far up the Forth but last weekend proved it is possible.
Also while scanning from Ferryhills on Sat, I was looking through the gulls in Inverkeithing Harbour and saw a likely candidate for an adult Argentatus Scandi Herring (darker grey mantle than nearby local Herring Gulls, but not as dark as LBB Gull) -this seemed on the early side for one and made me wonder if it was more likely a hybrid Herring x LBB Gull but there was nothing really to suggest this; the bird was seen preening and a had  massive all white tip to P10 as well as being a very large bulky bird clearly bigger than accompanying local Herring Gull. Yellow-legged Gull had also crossed my mind but the legs were clearly pink and too much white in primaries. Interestingly Whitburn, County Durham recorded their first Argentatus of the autumn passing this weekend see here

Also Sunday I checked Fife wader sites, Letham- 3 Greenshank, 2 Ruff, 14 Snipe, 4 Water Rail and 6 Black-tailed Godwits were my highlights (Other observers recorded more Ruff, as well as the continuing Spotted Redshank at this well watched location). The Wilderness-2 Ruff and 6 Black-T Godwits.

Sunrise at the watchpoint on Ferryhills, bring on the overland skuas soon.
