Can I remind Aberdeen people about Loirston Loch. Located near Cove, it is about 1km x 200m, with direct access from the dual carriageway. Is is accessible from the 3, 117 and 21(No evening or Sunday service) buses, provided you are equipped for a damp hike, but circular routes are possible (one small barbed wire fence and the main road). It is adjacent to an almost abandoned Country Park, dilapidated well beyond being charming, but has 2 hides which the birds do approach closely. This is particularly so now that the bird scarer scarcely revolves and the flag has collapsed. (Not me guv, honest, it was just old age.)
There are normally about 200 birds there, reliable just now are Grey Heron, Mute Swan, Cormorant, Goosander, Goldeneye, Widgeon, Tufted Duck, Mallard, Larus. The LBJs are starting to appear, and I see deer on 50% of my visits.
And of course despite being close to civilisation, there could be others.
You could spend all day going to Strathbeg, not see much more, certainly not the bird you went to see, and not see anything at less than 60 x magnification. Although you may get wet feet, you will see the birds close enough to use a camera phone.
The catkins are out, the Curlew and Oystercathers are around.
Go on, you know you'll enjoy an hour away from Mega potential.
