I'm all in favour of interest in conservation being popular. What's the downside?

JK, the downside of conservation for the Hen Harriers was 10s if not hundreds of people tramping around their nesting site every weekend

Combination of RSPB, Northumberland Wildlife trust and Forestry Commission Courting publicity, They were running Mini busses to the nest sites to facilitate viewing. Same sort of thing with the Kielder Ospreys, although at least the public area is a good mile away from nest that is publicised, there are other nests but at least they are having the sense to keep quiet about location. They still climb up to the platform remove chicks and ring and tag and fit GPS beacons to all the young Ospreys, then replace in nest, RSPB oversee, FC provide clmbers. so now the Ospreys not only have rings to catch on branches, wing tags to bugger their aerodynamics, but they also have a GPS transmitter glued to their back.

Thanks.

That sounds very close to the harriers' nest. Was the failure discussed?

I once went through the literature about disturbance from high-tech tagging for mammals and reptiles and it was surprisingly benign. I don't know enough about birds.

The RSPB here are a bit over zealous. They put up big eagle watch signs telling people they can't stop, obviously everyone stops to see what it is they shouldn't be stopping for.

JK not possible to discuss in a meaningful way with conservation folk, they are the experts. (sorry jaundiced view from past attempts) 

I have to say I have no rigorous studies or double blind trials to back me up, mind I am not sure the conservation people have either , re tagging and Sat trackng, just my gut feeling that anything that interferes with the air flow over a wing,  thats been developed over thousands of years, can only hinder, Just watch a Goshawk fly through trees to understand how beautifuly their control surfaces work.   It may not even be measureable in the short term, but I feel it must handicap the bird and however slight that is it cannot be a good thing. At the very best it is neutral, it cannot benefit the Bird.  In what way does an Osprey gain from the RSPB knowing its exact route to Africa? .

I love the irony of it being on the Otter.

Keep off the straight and narrow Thumb Up
