Common shrew jawbones. The enamel at the very tips of the teeth is red.

Badger hair: white at the tip, ridged when you roll it between your fingers.

Weighing one of the mammals we trapped. 

The Longworth traps are opened inside a bag so the animal doesn't leap away and escape.

Shrew in motion.

I think, going by tail length, we decided this was a pygmy shrew.

Bank vole.

Wood mouse. Scruffing small rodents is the best way to hold them; picking up a wood mouse by its tail can cause the skin to shear away painfully and permanently.

I was lucky enough to attend a Field Studies Centre course this autumn on mammal identification. The FSC run training courses for both amateur and professional ecologists, and cover a wide range of wildlife topics across their various schools: http://www.field-studies-council.org/ My course was at Preston Montford in Shropshire.

We were taught to prepare and set small-mammal traps, the correct way to check them and the proper way to handle and record the wild rodents we caught. We were also shown how to clean the traps after use. We looked at animal prints, nests, skin markings, scat, skulls and feeding signs, and listened to some common mammal calls. We looked at recording and reporting methods; we dissected owl pellets. At the end of the three-day residential course, students were invited to take an exam in Mammal Identification.

I'm delighted to say my certificate came this week and I got a Distinction, with 60 marks out of a maximum 64. So I'm very pleased because I enjoyed the course so much. Now I'm off to join the Mammal Society!  http://www.mammal.org.uk/

Foster Hedgehog

Wildlife rescue centres around the country are currently inundated with juvenile hedgehogs who need carers to feed them up to 600g, a safe weight for hibernation. I took myself down to the West Midlands centre and brought back two small hogs, one for myself and one for Lorcan from the Whitchurch Water Vole group.

We've been told to keep our hedgehogs warm and to feed them meaty (not fishy) cat food (in jelly, not gravy). A saucer of cat biscuits also goes down a treat, and they need plenty of fresh water to drink (never milk).We're weighing them every day or two, handling as little as possible, and when they attain their ideal mass we can put them in an outdoor sheltered place, like a shed or a garage, with a box or hutch from which they can come and go, plus food and fresh water. The hope is that the cold temperatures then will trigger hibernation, though the animals will still need to be checked every day and supplies renewed. Come the spring they can then be released into the wild.

Lorcan's blog charts our progress here: http://www.younghog.blogspot.co.uk/ My hog had a poor start as he had to be taken to the vet and wormed, but since then he's picked up strongly. Lorcan's female hog goes from strength to strength.

If you have a spare room and an unused hutch and think you could foster a small hedgehog, do google your local wildlife rescue centre because I know they'd appreciate any help they can get!

BBC Wildlife Magazine

Hello to new readers!

Cover-vole

Me, waiting for voles.

I'm the chapter on water voles in Hugh Warwick's gorgeous book about wildlife advocates.

Before She Was Mine: the only novel you're likely to read this year which tells you how to set up a mink raft.

*

I am thrilled to report that my own Whitchurch water voles form a seven-page feature in the November edition of BBC Wildlife Magazine (out today!). I write about what happens to water voles in the winter, and the article is complemented by the most beautiful photographs from Terry Whittaker, Jules Cox, Ben Hall, John Harding, Roger Wilmshurt, Simon Booth, Simon Colmer and Dennis Lorenz, as well as one I took of a vole chewing my boot.

If you're coming to this blog for the first time, welcome, and please check out my photos of field signs - use the labels on the right to pull out whichever sort you're interested in.

You can hear me talking about water voles on Radio 4's 'Saving Species' here, 16 minutes in: http://www.bbc.co.uk/programmes/b014fd21   

and here on one of Hugh Warwick's wildlife podcasts: http://www.urchin.info/podcasts/
You can watch my videos of voles and hedgehogs on my Youtube channel here: http://www.youtube.com/user/HarvyCola?feature=mhee

Lastly, this blog is fairly quiet during the colder months, like the voles it follows, but come spring there will be posts every few days as I follow the progress of my local colonies and record their activities over 2013.

Activity - if you look for it

We still have at least two hedgehogs coming into the garden, one on the early shift and one on the late. Early hog is smaller, but still a decent-sized adult.

Meanwhile a quick peep at the back of Saddler's Walk (Mossfields) shows the ditch to be full and healthy - rainy summers benefit this colony as the site easily dries out. This group of voles is notable for the number of feeding stations it always produces, always a lot more than other sites I survey. Though with the colder weather most water voles switch their diet to more calorific tubers and roots, these ones are still making piles of chopped sweet rush well into October. In the bottom photo, the vole has bent the blade down, folded it in half and made the usual diagonal cut, which then opened to make a point (would have been a V if the cut had been made from the other side).

Holing Up for the Winter

Blocked up burrow

It's more or less time to say goodbye to the voles for this year - I did spot one briefly this morning, but mostly they're packing away in preparation for the winter. They'll be storing high-calorie tubers and blocking up strategic burrow entrances, as in the photo above. Very little sign of feeding, except for gnawed iris roots, but are still plenty of droppings about, so I know the voles are around.

Looking forward to speaking at Walford College's Bioblitz this afternoon with Rosie Rees and Lorcan Adrian, stressing the importance of reporting sightings and disseminating vole information between various parties - landowners, the EA, the council, water authorities, the WT etc - and also the need to protect wildlife corridors as well as individual colonies themselves. 

Water Vole Heroes

I've lately been doing some research for a magazine article, and also for a talk at Walford College's Bioblotz
http://www.bnhc.org.uk/home/bioblitz/national-bioblitz/midlands/walford-college-bioblitz-shropshire.html
and it's struck me just how many people are working hard nationwide to save the water vole.

I've lost count of the folk who track and log these animals, who lobby their council planning departments, who travel the country taking wonderful photographs to raise the species' profile. This year I've met up with Richard Steel (link to his website is on the right); with Vicky Nall and team at the Cheshire Wildlife Trust; with Gareth Parry who's studying the effect of carnivores on vole populations; and with John Harding and Rosie Rees who've been putting together a film about water vole behaviour. The Whitchurch Water Vole group led by Malcolm Monie continue to do vital habitat management and survey work, and online I've been following vole news from Views of the Ock (link right) and Jo Cartmell, amongst others. There's a substantial network of men and women doing their best to halt the decline of the species and help build up numbers again.

But three people I've come across lately deserve a special mention for the good they do. The first is Rob Strachan, who currently works for the environment agency and co-authored what I believe is the definitive guide to water vole mitigation, The Water Vole Conservation Handbook. He also gives excellent talks and is a mine of information on riparian wildlife generally.

Secondly there's Derek Gow, a man who actually farms water voles: http://www.watervoles.com/ He offers training days to help with issues like translocation when voles need saving from building developments, and he provides voles for release when conservationists are trying to re-stock sites where those animals once were. To say he loves his work would be an understatement.

And lastly, Professor Xavier Lambin of Aberdeen university, who's been in the news this week with his findings of water vole dispersal models: http://www.bbc.co.uk/news/science-environment-19503827 Once again his investigations underline the need to preserve wildlife corridors as well as individual colonies themselves, and avoid habitat fragmentation.

It's good to have so many on the case, volunteers and professionals at all levels. Given the problems water voles face at the moment, they need all the allies as they can get.

Change of Behaviour with the Seasons

I'm already noticing a change in the way the voles are feeding, and moving about generally. Just a month ago they were happy to swim about openly in front of my camera and sit and eat just by my feet. Now they're dashing past at speed underwater, and the two I saw feeding tonight were working from the safety of tunnels, occasionally putting out their noses but that was all. I suspect it's to do with population density which is thinning out now the voles are dispersing to new sites. I know there are still plenty of animals about - the banks are still volescaped and there are lots of fresh droppings and tidy burrows, prints and chopped or grazed vegetation. These signs will gradually disappear, though, as autumn progresses.

The practical upshot for this blog is that I don't think I'll be getting many more photos; the pictures of voles at the top are some of John Harding's, taken earlier this year. However, as I usually do, I'll be keeping an eye on this colony and the others over the winter and cataloguing the first field signs as they appear in spring. In general it's not been a bad year for water voles in Whitchurch, mainly because we don't experience the severe flooding many other sites have had across the country, and because we've managed to keep the mink out for another season. Long may it continue!
