Why are rats different?

rats are not native to a lot of islands and the birds never evolved to cope with rat predation. The rats were introduced by man. In the same way Mink and grey Squirrels are not native and there is minimal controls on managing them. crows, weasels, foxes, badgers are all native species of the UK.

Non-indigenous rats on Lundy is a verified fact. Neither brown nor black rats are indigenous with both only having arrived in the UK with the advent of ship trade. Now, you could argue that throughout the UK a couple of millennia entitles an animal to be considered a native and you may be right, but a couple of hundred years certainly doesn't with regards to rats on Lundy.

Given the way the bloody things seem to love it so much in the UK - i always find it remarkable that the Brown rat didn't arrive in the UK until the 1730s.

I have no problem with the action taken to protect the birds on Lundy. What strikes me as hypocritical is that the very organisations that are behind this complete removal of a species are equally keen to prevent us as land managers from controlling (not eradicating, just controlling) other predators of wildlife. Maybe they were just lucky that the rats aren’t a protected species, but then again, who’s in charge of those designations?

Hedgehogs have been 'translocated' from the Uists to 'rescuers' on the mainland as they eat eggs. Is there any evidence to suggest that hedgehogs are not indigenous and native to the islands and the birds any different to mainland birds where their eggs are normally predated by hedgehogs?

Apparently my name came up as someone who might train the locals in the use of dogs to hunt them, but that got vetoed because my solution would have involved something a bit more permanent than they wanted! It would be interesting to know what that control and rehoming is costing them now.

A couple of years ago we visited Handa island off the Scottish west coast, to see the seabird colonies managed by the Wildlife Trusts. On arrival we were treated to an introductory talk and told that rats were live trapped and relocated to the mainland. Naturally we queried this, and were then told that of course the rats were killed, but telling us this might upset some of their visitors!

The most common rat outside London is actually the Norwegian rat. The Black rats that once spread the bubonic plague favour big urban population centres.

If you want to see who is the biggest licenced killer of raptors, I suggest you look at the Natural England website to reveal... The RSPB...

Call me cynical, but I can’t help thinking that rats are being blamed for reductions in wildlife on these islands because there aren’t enough farmers to pin the blame on.

And your proof is.......?

Historical records give us clear dates to work from, and they tally with the fact that there are no fossil or any other sort of records of either the black or brown rat before about 250 and 1720 respectively. Add to that the genetic studies which reveal the rate of mutation away from original populations and it becomes pretty clear that rats aren't native - as in they got here via anthropogenic means.

"Pretty clear" is not proof of a negative.

It was long supposed that the Normans introduced the rabbit. But recent evidence suggests they've been here since Roman times. But that doesn't disprove the hypothesis that they've been here a lot longer!

I still say the Black Rat should be reintroduced to Whitehall, it's native habitat, where the 'experts' could keep an eye on it and ensure it's welfare from the comfort of their centrally heated offices.
