Spring has definitely sprung

Yesterday I was keeping an eye on things at Blashford and after a bit of time finishing things off in the office (the last couple of days have been filled with emails, creating signs and cancelling events and school visits) I had lunch outside the back of the centre with one of our very friendly robins for company and decided to make the most of the glorious weather and venture out onto the reserve.

Being at Blashford with the car park empty and the sun shining did remind me of the very quiet days we have on the reserve in the summer, when you know everyone has headed to the beach and the coast to stay cool. The main reminder of spring was the increase in birdsong, it was lovely to hear chiffchaff calling, and also the new growth on the trees.

Nearing the entrances however it was apparent people were very much still out and about and there were a fair few cars parked up. Fortunately most people were respecting social distancing, however I did have to stand in vegetation at one point to allow a group to pass who were quite happy to walk, albeit in single file, down the middle of the footpath. Out footpaths are not that wide… so please do take care out there and give people space!

Keeping the car parks closed does encourage fewer people to visit the reserve, which gives everyone a chance to keep their distance, but it does also reduce the risk of fly tipping on the site. Between me leaving on Friday and arriving back on Sunday a large amount of rubbish, including a couple of single mattresses, had been dumped in the first lay by on Ellingham Drove, if coming from the A338, and although this may have happened over night we have in the past had fly tipping occur during day inside our gates on the approach to Tern Hide and also on the nature reserve itself, near the water treatment works. Although those who fly tip will always sadly find somewhere for it to go, at least having the reserve secure at all times will reduce the opportunities available for fly tipping on the reserve itself, where the site is now generally quieter and our staff presence lower. Unfortunately with quieter roads this issue is something that may sadly increase over the next few weeks and months.

My real reason though for venturing close to the entrance was to stare at the very fine display of moss growing on the top of the wooden fence by our gate. I had been waiting for a sunny day to photograph it and usually when I am passing I am driving, either having just arrived or heading home. After a bit of searching, I think it is capillary thread moss, but am happy to be corrected if wrong!

The hazel trees near the entrance are also displaying fresh bright green leaves and lesser celandine carpets the woodland floor below them.

I followed the path along the Dockens Water, spotting a brimstone butterfly but it did not settle for a photo. On my way up to Lapwing Hide I saw great tit and blue tit feeding amongst the willows and nearer to the hide itself chiffchaff, Cetti’s warbler, water rail and little grebe were all calling and I saw a reed bunting in the trees.

I also spied my first adder of the year, something I wasn’t necessarily expecting as it was now mid afternoon and had warmed up considerably.

On the edges of the paths colt’s-foot is flowering. It looks like a short dandelion but has a much rounder middle. Flowering early in spring, the flowers appear before the leaves do which has led to the plant getting the name ‘Son-before-father’.

Blackthorn is also blossoming and looking very pretty against a bright blue sky:

After walking round to Goosander Hide I cut back across to Tern Hide via the closed Hanson path and saw my first peacock butterfly of the year, which was more obliging than the brimstone and paused just long enough for a photo.

I popped in to Tern Hide to check all was well and see if there were any little ringed plover yet on the shore line. I couldn’t see any, or the common sandpiper which had been quite frequent, but did see teal, wigeon, tufted duck, goldeneye, shovelar, goosander and good numbers of pintail out on the water.

On heading back to the Centre I decided to keep following the path along the Dockens Water to see if there were any signs of flowers on the bluebells (not yet, but it won’t be long!) and also to check the boardwalk was still taped off at either end where it is currently closed.

The hawthorn along the path is another tree coming into leaf. Its flowers are similar to blackthorn, however hawthorn comes into leaf first, and will not flower until May, whereas the flowers of blackthorn appear before the leaves, as seen in the photo above.

All in all it was a very nice wander around the reserve in the sunshine. I am working from home today, listening to the chaffinch and dunnock singing outside, and will be doing so more over the coming weeks and months so it was good to get out on the reserve while I still could. I will be spending more time in my little garden and walking my dog down to the closest stretch of the River Bourne in Laverstock, or possibly up to the Laverstock Downs themselves if they remain quiet. So I will finish this blog with a photo of a primrose, as there are still plenty flowering on the reserve:

Thinning

Not a reference to the effects of advancing age but to today’s volunteer task on the reserve, which was felling some sycamore trees to open up some space. In places we have dense stands of very tall, thin sycamores which tend to over-top and then shade out other species. To reduce the negative effects of this we are thinning out a lot of the smaller trees, especially where they are growing amongst other species such as oak. It was the perfect day for felling, at least until the rain started, being cool, so I did not overheat in the protective chainsaw gear and calm, so the trees would hopefully fall where I intended them to.

By the end of the day we had cleared quite a few trees, but the more we took down the more there seemed to be! At the same time there was a more open feel to the area so we must have done something. We did come across quiet a few small, self-sown hazel and even one covered in honeysuckle and these should benefit from some more sunlight.

I left a number of the stumps fairly high, this allows me to ring-bark the stump reducing the chance of it growing back, without using pesticide and also gives the opportunity to make some cut slots and holes to allow rot to get a hold and make habitat for various invertebrates.

Chainsawing for most of the day does reduce the chance of seeing wildlife somewhat, but not completely. Locking up the hides at dusk I was lucky enough to see both great white egret and bittern at Ivy North hide. I understand the yellow-browed warbler was again near Ivy South hide and out on Ibsley Water there were peregrine, Mediterranean gullyellow-legged gull and black-necked grebe, but no sign of the lesser scaup, perhaps it has moved to Blashford Lake where it spent much of its time last winter when it was here. At Woodland hide there was also a brambling reported, perhaps the same bird that Tracy saw yesterday.

Laying around

Another busy day with lots of visitors, a volunteer work party and the Pop-up cafe. The bittern performed from time to time at Ivy North hide, including at dusk as I went to lock up. A water rail there was seen to catch and eat a small fish, which surprised some watching, in fact water rail are not fussy eaters and will happily eat vegetation, seed, and animal matter alive and dead. I have seen them eat fish and even small birds and they are a well known hazard when ringing birds in a reedbed, as they will try to pick birds from the nets given half a chance.

The volunteers worked laying another section of the hedge alongside the A338 on the western side of Ellingham Drove. This hedge was planted in 2005/06 winter and is being laid to thicken it up and make it more useful for wildlife and as a visual screen for the road.

After the hedge laying you can see it is already much denser even though some of the side branches have been removed.

Those of you that are familiar with the traditional craft of hedge laying will immediately notice that this is not a craftsman’s job. The traditional craft produced a barrier that would keep livestock in before the days of barbed wire, it had a woven line of rods on top between stakes and much more of the twigs and branches were removed. This art is still practised and there are regular competitions, to make a good traditional hedge in this way takes great skill. However we are just trying to thicken up the hedge and retain as much of the potential for flowering and fruiting next year and for this purpose some reduction in the branches and a partial cut to lay the stem over will suffice.

Such hedges make good nesting places for many of our common birds like robin, dunnock and blackbird.

This hedge is almost entirely made up of hawthorn, but we are trying to diversify it by adding extra species. One that we could add is hazel, normally we would plant these in the winter when the plants are dormant, but looking at the hazel around the reserve today they are anything but dormant.

hazel catkins

The catkins are the familiar flowers of the hazel, but these just the male flowers which open to scatter their pollen, the female flowers are much smaller and easily overlooked. Each hazel will have flowers of both sexes, the catkins on the ends of the twigs and the female flowers a little further down.

Although winter is natures “downtime” it is not so for all species and on the outside of the Education Centre door this morning there was a male winter moth.

winter moth

Winter moth (male)

When moth trapping you always catch many more males than females, probably because they fly around more seeking females, however in the case of the winter moth you will only ever catch males as the females are wingless. The larvae to these moths eat oak leaves are the main food collected by blue and great tit when feeding their young, one of the possible effects of climate change could be a disconnect between the timing of peak caterpillar numbers and hungry chicks. Only time and project s such as the one undertaken by Brenda at Blashford (see the last post) will show if this becomes a real problem for the birds.

I was trying out a new camera today, a replacement for my one that packed up the other day, it is a “bridge camera”, not something I have used before so I was keen to see what it could do. The light was not good today, but it seems as though it will be useful. I tried a range of pictures, standard shots a sat the top of the page, some macro and finally some using the full magnification, although not a great shot I quiet liked the one below of a group of pintail.

Hopefully we will get some better light and I will get the chance to put it through its paces rather more fully.

Birds, Beetles and Butterflies (and a bit more besides)

We are slipping into autumn, despite the weather remaining warm the signs are everywhere. Berries are ripening and birds are on the move. Over the last few days there have been between 500 and 1000 house martin over Ibsley Water, gathering before migrating south. On Ivy Lake numbers of winter wildfowl are starting to rise, at least 12 wigeon and 18 shoveler were there on Sunday and last week 3 pintail dropped in. In fact overall numbers of wildfowl are very high for the time of year, probably due to good weed growth.

Any visitor to Ibsley Water recently cannot have failed to miss the large numbers of cormorant and heron. They are feeding on the huge numbers of small common carp, a fantastic spectacle, but a sign of problems ahead. Such large numbers of small carp will grow into a very large population of medium sized fish which are likely to largely eliminate the weed and eventually most of the food for wildfowl.

Another very obvious feature at present is the lace-like leaves of the alders, they have been eaten away to skeletons.

The alder leaf beetles that are responsible are a striking metallic blue and were considered as an extinct species in the UK until just a few years ago, however their status has changed dramatically in the last few years and they are now not just present but super abundant. They seem to be everywhere at the moment and almost every alder leaf has been eaten away and they seem to have been eating hazel and even birch as well. Quiet why they have undergone such an extreme change in fortunes is something of a mystery.

We are now heading into autumn and the moth trap is starting to catch species typical of the season, perhaps none more so than the aptly named autumnal rustic.

Another autumn favourite of mine is the intricately marked feathered gothic.

The males use their feathered antennae to test the air for female pheromones, in effect using them to smell.

The main butterfly on the wing at present is speckled wood and they are very abundant this year, they are one of the few species that you can see throughout the season as they have a series of overlapping broods. Sometimes the first are on the wing before the end of March ans they can still be flying in November.

Autumn is also the fungi, actually they are to be found all year but many species are most abundant at this time of the year. When we were working today we came across a bright yellow patch on a log near the Woodland hide, but although many of the logs in that are are covered in fungi, this was not a fungus, but a slime mould called troll butter.

For those that like to venture up to the Lapwing hide in the winter or spring I have good news. The need to take the long way round or risk getting wet feet when the route through the reedbed floods will soon be a thing of the past, we are having a boardwalk constructed!

Cake and Colours

A fine Blashford day and better still one with cake, because we hosted the Pop-up Café once again today. The reserve was fairly busy, both with visitors and birds. At opening up time Ivy Lake was busy with ducks, nothing unusual, but a good mix of species.

The trees are in particularly good colour just now, with the oak just turning, joining the beech, hazel, willows and others. Some hazel are still completely green while others are in their autumn glory.

Although there are few on the reserve, the guelder rose draws attention at this time of year thanks to very bright leaves.

Field maple, like all the Acers, has very good autumn colour, although most of their leaves seem already to have fallen at Blashford.

Not all the colour comes from leaves though, I know Tracy posted a picture of it on Friday but I cannot resist another one of the cobalt crust fungus.

The colour is amazing! It seems it is uncommon and mostly found on ash twigs and branches, at Blashford it is on rotting willow branches lying on the ground in deep shade.

Out on the reserve both the water pipit and pink-footed goose were on show at Tern hide on and off throughout the day. Over 30 goosander were present well before dusk and 3000 or so starling gave a rather brief display before going to roost rather earlier than I had expected.  Three Cetti’s warbler were singing around Ivy Lake and a fourth was calling beside Lapwing hide. At Woodland hide a redpoll, a couple of brambling and a firecrest were all reported and a woodcock was seen in the willows near the Centre car park. At dusk on Ivy Lake, Walter our regular great white egret was again roosting in his favourite dead alder beside the cormorant roost.

Spring Between the Showers

On Thursday the volunteers were working out on the shore of Ibsley Water putting out fresh shingle patches for nesting little ringed plover and oystercatcher. Now that the old concrete block plant has been removed and the site opened up to the lakeshore there is a much larger area of suitable habitat for these species and for lapwing, so we have high hopes for the coming nesting season.

“Plover patches” small areas of fresh shingle ideal for nesting little ringed plovers.

It turned out we were just in time as on Friday the first little ringed plover of the season was seen! They are usually one of the first of the spring migrants along with sand martin. There are lots of other signs of approaching spring around the reserve now, the hazel catkins and flowers are out.

Hazel catkins, these are the familiar male flowers that produce lots of pollen.

The tiny female flowers are easily overlooked and very different, each tree will have both the catkins and female flowers, you just need to look closely to see them.

It is not just hazel that has catkins, those of alder are also out now and rather similar to look at.

I was also working with the volunteers today, although in less benign conditions, it rained and hailed and we took shelter by the Centre and made nest boxes. However Jim had thought to put out the moth trap and I was quite impressed to find it contained five moths, 2 twin-spot Quaker, a small Quaker, an oak beauty and a yellow-horned, so we got to see a little wildlife at least.

I did get lucky as I was opening up the Ivy North hide as the bittern was in the open beside the “pool” just below the western end of the hide, it must surely be thinking of going soon. At the end of the day I took a quick look at the gull roost, now mostly smaller gulls with about 3000 black-headed gull, only 21 common gull and just a single Mediterranean gull.

30 Days Wild – Day 11

Not a great day weather-wise, but this need not stop the quest for wildlife. Running  a moth trap in the garden helps as you never know what you might catch. This time it was two species that I rarely catch, although neither is at all rare locally. They were a female fox moth.

The males can often be seen careering wildly about over heathland in the daytime as they search out females. The females, on the other hand, fly at night, this one laid a number of eggs in the trap which I will put onto bramble in the garden.

And a female common heath.

Another moth that can often be seen flying by day over heathland and also one that, like the fox moth, shows strong sexual dimorphism, i.e. the sexes do not look very alike.

Also in the garden I noticed that my hazel was being eaten, lots of the leaves had been stripped and it did not take long to find the culprits, a group of hazel sawfly larvae. when they feel threatened they curl their tails up over their heads as you can see here.

Bittern by a Great White

Bird News: Ivy Lakebittern 1, Cetti’s warbler 1, great white egret 1, green sandpiper 1. Ibsley Waterblack-tailed godwit 1, Bewick’s swan 5.

Not nearly so bad a day for weather as I had expected, although the bright sunshine was occasionally interrupted by short but vigorous showers. This did mean the sky was made more interesting than just the plain old blue.

Ivy Lake from South hide

Leaving the Ivy South hide a large female sparrowhawk flew into a tree just beyond the silt pond where it attracted a carrion crowwhich spent a couple of minutes noisily dive-bombing it before it got fed up of the attention and swooped off.

Ivy Silt Pond

I spent a few minutes in the Ivy North hide in the hope of seeing the bittern, but no luck. I did see another sparrowhawk though, this time a very bright adult male weaving in and out of the willows along the lake edge.

As it was Thursday the volunteers were in again this morning. Before we met for tea two nipped down to the Ivy North hide for  a few minutes and came back with reports of the bittern walking right passed the hide in full view.

We were working in the woodland beside the Dockens Water today on a range of tasks including restyling some steps sue dot access the river, digging out a few self seeded rhododendron bushes, cleaning out the nest boxes and putting guards around some self-seeded hazels. The woodland has a good few large hazels, but very few small ones. There are a reasonable few seedlings, but they do not survive more than a year or two, I think this is due to the increasing level of deer grazing, hence the guards, which should give them a better chance to get established.

The work on the steps did involves the installing of some new woodwork and in moving the new posts I came a cross a rather fine and, in close-up, rather fiercesome spider, unfortunately I have failed to identify it so far, any ideas out there?

unidentified spider

I decided to try having lunch in the Ivy North hide to see if I could finally see the bittern. Lunch was fine, but the bittern did not show, although the great white egret did, I saw it there the day it arrived but not since. There was also a calling Cetti’s warbler, water rail and 3 bullfinches, so I don’t feel I can complain, but it would be good to see the bittern properly and I am pretty sure it was somewhere just out there in the reeds below the hide.
