Letting the Light in

For several weeks now there have been contractors working up at the Linwood reserve working to open up an areas of mire habitat that had become seriously shaded. This happens more or less imperceptibly, in this case it was easy to think the area had always been continuous woodland , but the flora told a different story. Many species present, although declining, were ones that do not tolerate being heavily shaded. In addition when the trees are looked at more closely it was obvious that many were no more than twenty or thirty years old. The Our Present, Our Future (OPOF) New Forest National Park project had a strand that was dedicated to helping to restore habitats such as this and it is this project that has enabled the heavy work to be done.

Work to clear shading trees from Linwood mire habitats

The oak and beech trees have been left alone, the opening up has been achieved by felling birch and pollarding willow. Some trees have been ring-barked to leave them as valuable standing deadwood habitat. It will be interesting to see how species such as white sedge and bog myrtle respond to having access to more light in the years to come.

Last night was very mild and I was looking forward to seeing what the moth trap had caught. The trap was against the wall of the Centre and there were 45 “November” moth on the wall alone! November moths are hard to identify reliably as there are a few very similar species, so I lump them together when recording. Other moths included three merveille du jour.

Merveille du Jour – I know I have used pictures of them many times, but they are one of my favourite moths!

There were also late large yellow underwing and shuttle-shaped dart as well as more seasonable black rustic, yellow-line Quaker, red-line Quaker, chestnut and dark chestnut.

Dark chestnut, it is usually darker than the chestnut and has more pointed wing-tips.

In all there were 16 species and over 70 individual moths, other notable ones were a dark sword-grass and two grey shoulder-knot.

We have been doing a fair bit of work around the hides recently, mostly aimed at improving the views from them. Tomorrow it is the turn of Ivy North hide, so I expect there will not be much to be seen in the northern part of Ivy Lake during the day. With luck I will get some sight-lines cut through the reeds, so perhaps the bittern will get easier to see, if it is still around.

Arrivals and Sightings

A quick update on the last couple of days. Yesterday I was working with the volunteers near the Lapwing hide, on the way there I flushed two water pipit from the shore and later one was showing really well at Goosander hide. These birds like the exposed stony shore and the piles of washed up weed, so they should be very happy with things at present with the lake so low. They winter in small numbers in the UK, but breed in the Alps, a rather odd migration strategy on the face of it.

Colder weather has heralded the arrival of more winter wildfowl, in particular goldeneye, which first turned up last weekend and have risen in numbers daily since,  today I saw 14 birds, including four adult drakes. Goosander numbers have increased markedly too, and I counted 51 at roost yesterday. There are at least two great white egret still on the reserve and two marsh harrier were seen yesterday, with at least one again today.

The colder nights have significantly reduced the catches in the moth trap, but despite this the last two nights have produced “November” moths Epirrita spp. , grey shoulder-knot, yellow-line Quaker, brick, satellite and black rustic. 

Reports and a Bit of Garden Wildlife

5th October reports from Blashford showed that all the main player are still present. On Ibsley Water the ferruginous duck was still around the north end of the Long Spit visible from either or both of Tern  and Goosander hides. The wood sandpiper seems to have relocated to the shore near Lapwing hide, with both common and green sandpipers also still present to “complete the set”. A few wigeon and a single pintail are mingling with the wildfowl and it is worth checking for the occasionally reported juvenile garganey. Both great white egret and several little egret were also about.

Over on Ivy Lake the bittern was seen on the edge of the reeds near Ivy North hide, viewed from the screen along the path between Ivy Lake and Rockford Lake.

I was not at Blashford myself so my wildlife sightings were restricted to my garden and especially the moth trap, a mild, calm, damp night resulted in a good catch of autumnal species.

The angle shades is perhaps the moth most adapted to hiding in piles of dead leaves and a species that can be seen as an adult all through the year.

dark sword-grass

The dark sword-grass is a migrant and although they can turn up at almost anytime, they are mush more frequent in autumn.

deep-brown dart

Whilst some autumn moths are yellow to hide in autumn leaves, others just go down the very dull and unobtrusive route, the deep-brown dart is one such species.

feathered ranunculus

feathered ranunculus

Feathered ranunculus is an autumn species that lives mainly around the coasts on cliffs. It colonised the mainland coast of Hampshire in the late 1970s. I remember this well as I was working at Titchfield Haven at the time and caught a number of them, indicating that there were established on the mainland and not just wandering from the Isle of Wight.

southern chestnut

southern chestnut

The southern chestnut was first discovered in Britain in 1990 in Sussex. At the time it was considered that it had previously been overlooked, this may be so, but what is certain is that it has increased greatly since and is now quiet frequent across the New Forest heaths and in similar habitat elsewhere in southern England.

Other species in the trap included large yellow underwing, lesser yellow underwing, lunar underwing, willow beauty, shuttle-shaped dart, black rustic, turnip, sallow, pine carpet, spruce carpet, cypress carpet, square-spot rustic and broad-bordered yellow underwing.

I have recently found a new species in my garden, a most unusual plant, called yellow dodder. The dodders are parasitic plants that have roots only as small seedlings and once their tendrils have found a host the tap into the plant to gain all their nutrients and do away with their own roots. There are native species of dodder that can be seen on gorse and heather plants, especially in the New Forest, yellow dodder is not a native and comes from the Americas, almost certainly with bird seed and most likely in nyger seed and this plant was climbing up a self-seeded nyger plant, supporting this idea.

Comings and Goings

It finally seems as though the grey phalarope has left us, I am  surprised that it has not gone before now, the nights have been fine and apparently idea for flying. The wood sandpiper remains though and turns up fairly regularly in front of the Tern hide giving very good views. They are one of the most attractive of all waders and this one has proved very popular with our photographers.

The phalarope may have left but Ibsley Water was playing host to a new scarcity today, perhaps not entirely unexpected but still good to see, the drake ferruginous duck has returned. At least it seems safe to assume that it is the same bird that has been coming since October 2010. It usually arrives in late September and is often on Ibsley Water for a day or two before going to the, difficult to see, Kingfisher Lake. I have no idea why it does not go straight to Kingfisher Lake or why it stays there so determinedly once it does get there.

In other news today the, or perhaps a, bittern was photographed flying across Ivy Lake again, I assume the same as in early September but who knows. As I was talking to a contractor outside the Education Centre I thought I heard the call of a white-fronted goose, I discounted this as a mishearing but then saw a small long-winged goose fly over, so I am pretty sure it was actually a white-fronted goose, but where it had come from or where it was going in anybody’s guess.

The moth trap is still attracting a fair few species, although nothing out of the ordinary, today’s catch included: large wainscot, black rustic, white-point, lunar underwing, large yellow underwing, sallow, barred sallow, pink-barred sallow, brimstone, snout, straw dot and lesser treble-bar. A lot of autumn species are yellow, no doubt helping them to hide amongst autumn leaves.

I also managed to record a moth as I was locking the gate this evening, or rather the caterpillar of a moth, as there was a grey dagger larva on the main gate catch. The adult moths are difficult to identify with certainty as they are very similar to the dark dagger, however the caterpillars are quiet different.

A little bit of everything…

Yesterday our Young Naturalists were back at Blashford for a varied session in search of birds and fungi and a practical task in our camp fire meadow. Kevin and Jack, BTO bird ringers, were ringing at Goosander Hide in the morning so we headed straight up there to try and catch them before they had finished. Whilst we were there, we were lucky enough to watch Jack ring a robin and a chiffchaff and talk us through the process.

Thank you Kevin and Jack for taking the time to chat to the group and explain what you were up to and looking for, giving a great overview of bird ringing.

Whilst in Goosander Hide, Young Naturalist Talia took some great photos of some of the birds on Ibsley Water:

It was then time to rummage through the light trap which revealed a really nice variety of moths for us to identify, including this lovely Feathered Thorn:

The most abundant moth by far was the November moth sp. but we also had the following:

Close to the Education Centre we found this fantastic Shaggy Ink Cap, which sadly by this morning had become too top heavy and is now in two bits! Unfortunately this photo doesn’t do its size justice, it was super tall!

After lunch it was time to do something practical and we spent the afternoon in our camp fire meadow, raking up the vegetation strimmed by volunteers Emily and Geoff in the morning. We also cut up some of our old den building poles to use as firewood, as these will be replaced with new poles cut over the Winter.

We finished our time in the meadow with more toffee apple cooking over the fire, with newcomers Gregory and Jodie having a go at fire lighting and old hands James, Cameron and Talia showing how it’s done.

With time left at the end of the session, we checked our mammal traps in the loft which revealed two wood mice, who had ventured into the building where the nights are now cooler.

Finally, we went on a short walk to Ivy South Hide, spotting fungi on the way and a Red admiral butterfly making the most of the October sun’s warmth:
