Hi Dave, welcome to WAB.
I've made my views on the "Peregrines vs Pigeons" debate known in the past, and I'm reluctant to revive it. However, as you're new here, and as I birdwatch regularly on the Orwell, I suppose I'd better respond to this.

Where did you get this information? I wasn't aware of any marked decline - did Mick Wright make a connection with Peregrines, or is this your own inference?
I know Mick, in his capacity as SWT warden at Trimley Marshes, so I'll ask him about this next time I see him.

Possibly, but so what? Are you implying that Peregrines kill more birds for this reason? If so, do you have any evidence for this?

Forgive me, but what do lions have to do with anything?

What do you mean by "placing these birds"? If you mean "introduced", and you're referring to the birds now nesting on the Orwell Bridge, they weren't "placed" there. A nestbox was placed on the bridge in '05 or '06, but the Peregrines were already present, and would probably have nested on the bridge anyway, if it hadn't been decorated with anti-pigeon netting.

Why?

Peregrins kill at speed on the wing some call it majestic spruce it up how you like it kills other birds. |
Your point being...?

I'm not sure what you're getting at here.

Nonsense. Visit any major British estuary in winter, and you will find a Peregrine or two. Peregrines are an integral part of estuary ecology, and have been for thousands, probably millions, of years. They were certainly wintering on the Orwell long before the bridge was built, let alone any nestboxes provided.
As I said above, I'm not aware of any significant decline in either wintering or breeding waders on the Orwell, but I'm open-minded as to the possibility, and it wouldn't really surprise me if it was true. I find it difficut to believe, however, that the arrival of a pair of breeding Peregrines is going to have the sort of impact you appear to be suggesting.
Apart from the fact that the Orwell is mostly important for wintering birds, and Peregrines breed in the summer, I can think of a number of other possible reasons why numbers may have declined.
For example:
1. Increased recreational use of the estuary, particularly water-based activities like yachting, jet-skiing, bait-digging etc.
2. Increased overflights by helicopters. A survey carried out a few years ago on the Stour discovered that 60% of disturbance to feeding waders came from helicopters. This sort of disturbance to feeding birds is potentially very serious, and as the area is now being used for training RAF Apache pilots, it can only have increased.
3. As I expect you are aware, 20-odd years ago the Orwell estuary was the site of two major construction projects; the Orwell Bridge at one end of the estuary, and Felixstowe Docks at the other. I've only been in the area a few years, and can offer no evidence for the hypothesis, but I would not be surprised to learn that the ecological consequences of these immensely disruptive projects include a decline in the numbers of waders on the estuary.

Sorry, but that's impossible to forget. You clearly have a personal, anti-Peregrine, agenda here, thinly disguised as a concern for the ecology of the Orwell. Are you a member of the Songbird Survival Trust, by any chance?
