A chilly start today with the car temperature gauge reading -1.5 in the estate and -2.5 out on the open road. 
First stop of the day was a Stirlingshire Black Grouse lek which can be watched from a vehicle on the road with no disturbance to the birds. Even while it was still dark the bubbling display call could be heard and there were brief flashes of white undertail coverets. When it was light enough to see clearly, it became apparent that only one male was present.After a while, he was joined by six females (including one that fanned her tail and paraded up and down like a male) and he was still actively displaying when I left at 06:30.
Next port of call was Balloch Country Park where I was hoping to find a passage diver or grebe on the loch. As luck would have it, none were present but highlights were singing Nuthatch, screeching Jay and probable Green Woodpecker at two sites.
