It's only a glimpse but is on two cameras and well worth a look. The dog otter went past with a huge eel, almost as long as himself. What a pity he didn't stay to eat it in front of the cameras. I have slowed both down to quarter speed to make it easier to see the action.
Basil Dean, an Environment Agency specialist in river restoration and currently seconded as a Development Manager to the Ouseburn Way project, says he has long suspected that there are large eels in the lake as the habitat is perfect for them, so it is good to have proof. My cameras have previously recorded otters with fish, a rat, moorhens, ducks, frogs and now an eel. As long as it is meaty, if they can catch it they'll eat it.
Eels are a favourite food of otters but I expect most of those they catch are smaller than this. I can't imagine that he could eat it all in one go and I suspect he didn't need to go fishing for another night or two. The European eel population has declined by 98% over the past 40 years and the species is now on the IUCN Red List. And it's not because otters are eating them all - the principle causes include pollution, loss of habitat, climate change and physical barriers to migration, so it is good to know that this is somewhere they can thrive (if they stay out of the reach of the otters).
In other news, as they say. The otter cubs are still with their mother, or at least two of them are. The last time the cameras saw all three plus mother was 10th April but I can't tell if the two are always the same two. The cub with a bad leg is still there and is almost back to normal. The cubs are now 10 months old and are likely to disperse soon, perhaps this month. I think all three are still around because I am often seeing a solo otter (not the dog) and quite often it is whistling a contact call. It could be that one (or more) is already semi-independent but still in the territory. Here are all four in April - the middle cub is the one with the limp but you can see it doesn't look too bad.
And here is the latest play fight. When it involved three cubs the mother always joined in but this time she just let them get on with it. It's a bit disjointed as a lot of the action was off camera and it was a misty night with some of the cameras a bit steamed up but it looks like fun.
The previous three litters all left at about 10 months of age and each time it seemed that the mother initiated it by courting the dog otter. From the timing of things I suspect that the present female has been the mother of the last four litters but I can't be sure. Female otters generally only live long enough to have two or three litters so, if I am right, it may be that this female won't breed again. It will be interesting to see what happens in the coming weeks. More news soon.
