Encouraging stuff. The other thing they need to do is to stop those maniacs driving their 4 wheel drive vehicles all over the habitat and destroying it for amusement. There are pressure groups for this leisure industry which insist that they have the right to do whatever they like because they are in the USA. I don't think Abraham Lincoln had that in mind.

that's such a good idea and curbs behaviour also. as an aside us british are the biggest bird feeders apparently too. CB

Very interesting.
Thank you
