Perhaps, but it gives the perfect opportunity to study birds whilst they're feeding and settled. Then you can wander the Foulshaw Moss reserve and find them for yourself. And should you chance upon them elsewhere in Cumbria you'll know what you're hearing and seeing. And viewing birds from the Foulshaw hide, you are close enough to take photographs without disturbing them.
Water rail are secretive but food scattered below the feeders tempted a bird to come foraging. You rarely have such an opportunity to see plumage details and that glossy red bill.
On a bright winter's day the rich colours in the Foulshaw landscape are stunning.
