In a location like that, it would help if you could find out how many nests are in the area. From there you can take a wild guess as to how many might show up. My experience is with coastal New England (USA) osprey so your mileage may vary! The ones I'm familiar with will usually eat about twice a day, in the morning and late afternoon. This can vary depending on the size of fish and how successful their fishing trips are. When they are here, they are here to reproduce and the male will fish for the female who, after laying eggs, will spend most of her time on the nest incubating. That time frame is good for about 2 successful dives per male per day. If there are 5 nests in the area, that's not much action. Once the little ones hatch, the demands on the male increase and as they grow, each chick can eat a fish or two per day. Thus, more dives! Finding out when the eggs hatch and waiting 30-45 days should get you the best odds of getting dives.If its the river Gwash hide at Rutland UK I can confirm its really tricky there. Its a working Trout farm , they have an Osprey or two visit there every year after the Trout . The visits from the birds can vary and you only get a few hours early morning or evening in this paid for hide . Sometimes you may only get one bird visit and one dive during your visit , also they may come in and dive from behind the hide depending on the wind direction. The hide opening viewing window is small and awkward ,its extremely difficult to follow the bird in such restricted conditions and you often get little chance to manoeuvre the lens in time . Its also in a valley so lighting can be bad , last time I went I was at ISO8000-12800 1/1000-1600 with my A1 200-600 , I also took my D850 300mm f2.8 but the A1 was much better suited for it despite the much slower lens .
Best I got with the D850 was auto AF , it missed quite a few but I thought it did better than group , anyway good luck.
Osprey repeat behavior, so as long as they can get fish, they will come back to the same place to get it. They do fly up to 10 miles when they fish but like all raptors, they prefer to get their groceries close to home!
