Fish Island


In the latest quest to get the Ouseburn Otter to 'perform' in front of the cameras, Bob has built himself a fish island. That is, a mini island in the middle of the Ouseburn river to which Bob has pegged a large and rather delicious piece of fish. The idea is that the Ouseburn Otter will pass this island on one of his jaunts down the river and not be able to resist the lure of a free and very large meal. As discussed before, this large and prominent structure in the middle of the river should also prove irresistible to him (the otter not Bob), thus causing him to pose and frolick on said island, right in front of the cameras. I doubt the Ouseburn has ever offered something this good!

So far (one night), all that Fish Island has been able to attract is rats. So, on the learning side of things, who knows the difference between a rat and a watervole? Well, a water vole has small hidden ears while the rat (as seen in the video) has big ears - pretty easy to spot really. Water voles also have blunt noses (as opposed to a rats pointy one) and a shorter, furry tail (i'm sure you've all seen a rat in a petshop which has a long, pink, scaly tail). Less obvious differences include a water vole's fur which is silky and midbrown (a wild rat's is more grey) and on jumping into the water, a watervole makes a distinctive 'plop' sound. Why is this important? Well, water voles have disappeared from almost 90 per cent of the sites they occupied in the UK in the last 60 years, a fact which we can all do something about. Although American mink can largely be blamed for this decline, so can human interference - water voles are commonly mistaken for rats (hence the ID lesson above) and are prosecuted because of this. We have also had a lot to do with the destruction of their habitat and pollution of waterways, not making it easy for those water voles clever enough to outsmart the mink to survive. Lesson over but please try to remember these differences and think before you carry out any kind of 'pest control' near waterways.

The rain has (once again) set in so I think I'm going to have to pull on the old waders and the waterproof coat (once again) and go and rescue my cameras (once again). I can't bear the thought of Bob falling over that prickly, prickly hedge and heading downstream all for the sake of my cameras!

PS I hope that with your (perhaps) newfound knowledge you spotted the picture above is of a watervole and NOT a rat!
