Hi Skirge
Mark has basically covered the main spots and my thoughts. What you will find will very much depend if we're still in winter, or if spring has arrived. But Ospreys should be in situ and paired up unless the winds have been wrong for their migration. Short-eared Owls will likely be back on the moors and a good place to try is the top of Moulin Moor, just east of Pitlochry, plenty of parking places to pull in to and scan from.
The Birks of Aberfeldy is maybe worth a short walk too, for Dippers and maybe Grey Wagtail. Not sure where "Toon" is, so don't know what you will normally see in your area.
The National Trust Reserve can be accessed either from the visitor centre near Killiecrankie, or from the car park at Gary Bridge (you need to pay either way!). Though this is a really lovely walk, it is best for summer visitors but you could hit lucky with some early arrivals.
You will find Ospreys on most lochs and they fish in the rivers too.
If the weather allows, go right to the end of the road to Rannoch Station, taking your time to view. Possibility of Golden Eagles and returning waders (Golden Plover, Oystercatcher, Lapwing, Ringed Plover, Curlew etc breed on some of the moorland) and divers pass through on their way to the north-west coast, resting up on the lochs for a day or two. And of course there's the
chance of both Red and Black Grouse
Return via the little road on the south side of Loch Rannoch.
Most of all, enjoy the scenery!
