Essex adder challenge

Danbury Common near Chelmsford in Essex is a National Trust site that is a mixture of woodland and heathland and is renowned for reptiles, in particular teh European adder (Vipera berus). The weather for the last 2-3 weeks has been ideal for resurrecting hibernating reptiles so myself and my friend, Dave, who is a very accomplished nature photographer, went along to try to get some pictures of adders. They are the only venomous reptile native to the UK and their preferred habitat is heathland. Dave originates from Essex and is familiar with Danbury Common and assured me that we would definitely see adders, so I was rather excited as I’ve never seen a wild one before.


The heathland terrain was perfect reptile territory, there are substantial areas of gorse and heather intermingled with bracken

Unfortunately two events conspired against us: the weather on Saturday morning was the coldest it has been for weeks and with 100% cloud cover there was little warmth to entice the adders out of their burrows, and secondly there had been an accidental fire right over the main hibernaculum, all of which resulted in the total absence of adders and any other reptiles!

Despite that, the Common is a great place for wildlife so we wandered around to see what else was in residence and were rewarded by the first blackcap (Sylvia atricapilla, Dansk: munk) and chiffchaff (Phylloscopus collybita, Dansk: gransanger) sightings of the year for me.


A male blackcap, one of a pair

Until recently blackcap were considered to be summer migrants to the UK, spending there winters in sub Saharan Africa and as far down as South Africa.  More recently they have been winter residents too and it is thought this is the result of westward migration of birds from eastern Europe and also from the Low Countries, not our summer residents staying put. They disappear from my regular haunts around Histon in the winter, but my friend who lives on the other side of the village, just half a mile away, has been hearing them sporadically through the winter.

I heard several chiffchaff and saw a couple too, but they didn’t come close enough to photograph, but the woods were full of great tit (Parus major, Dansk: sortemejse) which were more amenable to pose for a portrait:

Backwarden nature reserve and Danbury Common are bisected by a road and Backwarden is an area of woodland containing sycamore, oak, birch and willow similar to that on the Common. Many of the trees were hosting various fungi including moulds and these brackets growing out of the stumps of felled trees:


…and this amazing mass of gelatinous psychedelic slime mould which I thought resembled candle wax:


I’ve never seen anything quite like this before but it appeared the sap had welled up out of the felled tree and the sugar rich solution was providing a glut of nourishment to opportunistic fungi.

The highlight of the trip, in the absence of snakes, was a weasel (Mustela nivalis) which bounded across the path and stopped to scrutinise us for long enough to take a couple of photographs. It’s years since I’ve seen weasel and we had to zoom in on the pictures to decide whether it was a weasel or a stoat (Mustela erminea). The stoat is around 30cm long so is bigger than the weasel which is around 20cm, and the stoat has a black tip to its tail which our little creature didn’t. Stoats go completely white in the winter except for the black tip of their tails and it is the pelts of the winter stoat which are used to make the ermine gowns of members of the UK House of lords.


Momentarily distracted by our presence

Then probably a potential prey item. Ready…

Set…

Go!

And he was off, like a brown furry exocet, at quite phenomenal speed. The pictures aren’t very good quality, but you can clearly see what he is and it may be a good few years before I get to photograph another! I’ll try to get to Danbury again over the summer and if I manage to take some pictures of an adder I’ll post them here.

More signs of Spring

The weekend before last, the 3rd/4th of March, was generally pretty murky and grey and generally not very pleasant, but a stroll around the fields and meadows of Histon showed up some encouraging signs of Springtime. To start with, several birds including blackbirds and house sparrows were plucking nesting material out of the shrubbery in my garden.

And in the meadow the buds of the willow, ‘pussy willow‘, were bursting out

…and amongst the buds was this little dunnock singing his head off. Dunnock (Prunella modularis, Dansk: jernspurv) make a big sound for such a small bird. You can here the song here.

And other birds which are all adding to the avian orchestra around here at the moment are the green woodpecker (Picus viridis, Dansk: grønspætte) whose striking call I posted a link to a short while ago:


Not just one green woodpecker, but a pair. There are lots of these in the meadow but it’s seldom I see two together, and even more seldom they let me photograph them!

And this delightful wren who sat high and sung loud

I was very pleased with my wren picture because I rarely see them in a suitable place and they’re usually flitting in and out the undergrowth and don’t stay still for long enough to photograph. And even though it was very murky that morning and I had to use ISO 400, I like this shot. Like dunnock, wrens also make an amazing sound for such a small bird. And wrens (Troglodytes troglodytes, Dansk: gærdesmutte) really are tiny, they are 4-5cm long and weigh approximately 10g but they make a huge sound which is easily recognisable as it’s punctuated by short stretches of ‘whirring’ which differentiates it from other small bird song.

And the last thing to catch my eye on this trip was this tree bark. I couldn’t tell what type of tree it is so I’m waiting for the leaves to open so I can give it it’s proper name, but it has some wonderfully textured bark which is covered in a white mould:


I had to get down and crawl through the leaf litter to get to the base of the tree

Lots of early Springtime phenomena were going on, from pairs of green woodpeckers to singing wrens and blackbirds collecting nesting material. More Springtime firsts next post.
