The Willow Screen

I went down to the reserve today to fill up the feeders to find that the willow screen had been tampered with. There is now a gap, almost one foot high at eye level of the average person in the screen.
This infuriates me. It is an act of pure vandalism, and the thing that annoys me most is that i am certain that the people responsible for this are bird watchers!!
Do people not understand the purpose of hides and screens? Yes, it to to give people the opportunity to see the wildlife, but more importantly, it is there to prevent DISTURBING the birds. The way things are now, there is little to no chance of any birds breeding close to the screen or at that side of the loch because some thoughtless individuals have taken it upon themselves to create a gap in the screen so they can see better.
I just can't believe that bird watchers would be so inconsiderate to the actual birds and so self-centered. They are clearly only interested in what view they get of the birds, not on the impact this has on the birds themselves. For me, the first rule of bird watching is to do so WITHOUT disturbing the birds.
If the people responsible for this read this, i hope they are ashamed of themselves. They've clearly put no thought into the disturbance they have caused and the results will continue to cause to the birds and also no thought about the time and effort David Blair and his conservation team put in to erect the screen for the benefits of the birds and for the people. I don't expect the people responsible for this to come forward or to make amends. I suspect that they will show true cowardice on this front.
Please be aware that anyone seen tampering with the screen, or on any other part of the reserve will be reported to the police for vandalism. Enough is enough now. It is a nature reserve, for the benefit of nature. We don't need these bad elements spoiling it.

On a slightly different note, please be aware that some sheep from the Flying Flock are now using one of the meadows on the reserve. Please keep dogs under control at all times to avoid worrying the sheep.
And on the dog front. Please pick up after your dog. I don't like stepping in it, and i'm sure nobody else does either. It has no benefit to the nature interests on the reserve, so please remove it.

Anyway, i think I've ranted enough for now. Again a reminder that anyone seen causing damage to any part of the reserve will be reported for vandalism. I welcome any comments, both positive and negative to this post.
