We’ve Got the Blues, Again

Tomorrow I have a moth event at Blashford, we will be opening two moth traps and looking through at the catch, identifying and photographing them. Over the last few days we have caught three Clifden nonpareil moths, also known as the blue underwing, this is a spectacular species and probably the UK moth with the largest wing area. In fact there was one yesterday and another today, obviously it would be great if there was one tomorrow, but things being what they are I suspect there won’t be! It is also still quite rare nationally, having only recently recolonized the UK, luckily for us the New Forest area is probably their stronghold.

The caterpillars feed on aspen and probably other poplar species, as it happens we have a number of aspen at Blashford Lakes, which is probably why they seem to be established on the reserve. Aspen is an interesting tree as is has quiet a lot of insect species associated with it. It is a tree that can grow very tall, but also produces lots of suckers, so there can be niches for species that prefer the canopy and shrub layer provided for by a single tree. It is very prone to being browsed and the suckers are often eaten off, increasing numbers of deer are probably one reason that aspen is in decline in many areas.

We may not see a Clifden nonpareil, but I hope we will see a good few moths and one thing that I am fairly sure about is that a number of them will be yellow or orange, autumn is the season for yellow moths, probably because it is the time for yellow leaves.

Although autumn is well underway now there at still quite a lot of insects about when the sun comes out, southern hawker, migrant hawker and common darter dragonflies are still around in fair numbers and butterflies include red admiral, comma and a lot of speckled wood. As I was eating lunch yesterday I noticed a fly on the picnic table next to me and realised it was one of the snail-killing flies.

It is the larvae that kill the snails, in the case of this species , aquatic snails, which is probably why it was close to the Education Centre pond.

Goings on

This Sunday we are holding our annual Lymington and Keyhaven Nature Reserve Open Day. For details see: 2017 Keyhaven event flyer

It is a joint venture with the Hampshire County Council, Hampshire & Isle of Wight Wildlife Trust and the New Forest National Park to celebrate the wildlife of the marshes between Lymington and Keyhaven. There will be a range of local conservation groups present and a range of walks, bird ringing, a seashore search, birdwatching, activities, light refreshments and much more. If you have never been to the reserve or have but would like to find out more come along, all the details are in the link.

Talking of events I will also flag up that on the following Sunday, the 24th September we will be hosting the Bird Trail Event at Blashford. This is aimed at young birdwatchers and there will be a number of teams going around the reserve that day, so the hides will be very busy and I would suggest that regular visitors might like to give us a miss that day. The event is jointly organised between the Wildlife Trust and Hampshire Ornithological Society part of our goal of bringing on the next generation of wildlife enthusiasts. As well as using the hides the area around the Centre will be busy with other activities.

A Day Unparalleled

Although I failed to see it a when I opened up this morning, the grey phalarope remained on Ibsley Water as did a juvenile black tern and the two ruff. A feature of recent days on this lake has been the mass fishing events, when a flock of cormorant, sometimes a hundred or more will act together to drive  large shoal of small fish into a corner. This attracts grey heron, little egret and the great white egret, which patrol the shallows, everyone gets some fish, sometimes several, which shows just how big the shoal must be.

The swallow and martin flock was perhaps a little smaller today, but still ran to several thousand and once again included a single swift. However it was not the birds that made for an “Unparalleled” day, it was a moth, a Clifden nonpareil, or blue underwing.

These are very large and, until recently, very rare moths. Having become extinct in the UK they turned up only as rare migrants until recolonizing about ten years ago. The New Forest area seems to be their stronghold now and in the last few years we have seen one or two each year, but they at still a real treat. It is just a shame it did not turn up yesterday for the moth event.

We have been doing quite a lot of grass cutting recently, some areas we are managing like meadows to increase the variety of wild flowers and this means we have to cut and remove the bulk of the grass by the end of the growing season. Today we cut areas of the sweep meadow used by education groups near the Ivy North hide. In this areas we cut in alternate years to leave longer herbage for over-wintering insects. If we leave it uncut for too long bramble and small trees start to colonise and many of the grassland plants, upon which so many insects depend, disappear.

The grass is raked up and piled into a heap which should provide a good place for grass snakes to breed next year, especially if the heap is in a sunny spot.

A Black and Grey Day

That is black as in the tern, as there was another juvenile black tern today and even better, grey as in grey phalarope!

Yet another in a proud line of “record shots” of wildlife at Blashford, my excuse is that it was a long way off and I have to say to is much better than my efforts the last time we had a phalarope at Blashford. Of course it should not be here, it has been blown in by the north-westerly gales and Ibsley Water was just the nearest thing to the open sea that it could find.

Despite the phalarope and black tern and a supporting caste of 2 ruff, 2 dunlin a ringed plover and Walter the great white egret my personal show-stopping wildlife spectacle of the day was actually the house martins. Thousands and thousands of them, I think at least 8000, possibly even more than 10,000 at the start of the day. They swarmed over the water like gnats with a 1000 or so swallow a few hundred sand martin and still a single swift.

I had an autumn moth event this morning, I was a little concerned we might have no moths to look at after yesterday’s paltry two moths, luckily it was not quite that bad. The highlight were 2 feathered gothic, the first of the year, others included snout, pinion-streaked snout, frosted orange, canary shouldered thorn, square spot rusticautumnal rustic and a few micro-moths.

A Full House

The poor weather over the last couple of days has brought in huge numbers of hirundines, that is swallows and martins, to Ibsley Water. there are especially very large numbers of house martin, they are impossible to count but I estimated at least 5000 today with probably 1000 swallow and at least 500 sand martin. Everywhere you looked over the water there were birds and then, scanning upward against the clouds there were many, many hundreds more. These higher birds are mostly house martin the swallow and sand martin tend to keep lower. They gather over water in an effort to find insects in weather when there are few flying elsewhere, often they pick prey directly from the surface of the lake.

The other aerial plankton feeder of summer is the swift, they mostly leave around the end of July, but a few can linger and searching through the hirundines can sometimes result in finding one and today was just such a time. Swift in September is a scarce bird, in fact in some years I don’t see one after mid August.

Other birds today included a hobby, lured in by the masses of martins as potential prey, although I did not see it catch one. The great white egret was around on and off, the ruff of the last few days was joined by another by the end of the day, when there were also 2 juvenile Arctic tern. A single black-tailed godwit dropped in for a while and there were 2 sanderling reported.

This is really not the weather for moths, so tomorrow’s planned “Moth Event” promises to be a bit of a damp squib. Today’s catch total a massive two moths! I suspect tonight may well be worse. The highlight was a fresh frosted orange, always a nice sight.

Several people mentioned the very good show of flower put on by our small patches of heather near Ivy North hide this year, in fact there at small patches of heather in several places across the lichen heath and I suspect these will expand in the coming years. All of this heather is the common ling, but we do have one plant of bell heather Erica cinerea on the reserve and this is in full flower now, somewhat after the ling has finished.

Although it is feeling very like autumn already there are still some reminders of summer out there, such as grasshoppers, I found this somewhat atypically coloured field grasshopper near the bell heather at the end of last week.

An Alien has Landed

We run a moth trap at Blashford on most nights of the year, we record the species and numbers. Some species are regular and others we see only once every few years and just occasionally we get a new species. When I opened up the trap yesterday morning there was a moth I had never seen before, small but quite distinctive.

IMG_8172

When  I looked in the book I could not find it, luckily the internet came to my rescue and I managed to identify it as a Pyralid moth, Musotima nitidalis a species native to Australia and New Zealand and first found in the UK in 2009 near Bournemouth.

So how did it get here? It appears it feeds on tree ferns and is likely to have been introduced with plants imported from Australia. It seems it will feed on some native fern species here, such as black spleenwort and bracken. Now it is here it will probably stay, perhaps as a scarce insect having little impact, or perhaps not. Once alien species establish the consequences will only become clear many years later and certainly there is nothing we can now do about this particular one but wait and see what happens.

Fishing in the Rain

The last two days have not been the best, I think it rained, even if only lightly, for the whole time I was at Blashford on Sunday. It did not put of the monthly volunteers, or at least not completely, four stalwarts came in and spent nearly two hours pulling nettles from along the paths and around the wild daffodil bank. The rain did stop everyone from coming to my planned “Late Summer Wildlife” walk though and so they all missed the two black tern that spent the afternoon over Ibsley Water and the thousand or two of house martin and swallow too.

Iblsey Water has had a lot of fish eating birds on it lately and Sunday was not exception with both grey heron and great crested grebe hunting close to Tern hide.

There have been well over 70 grey heron on a number of days recently and my maximum count was late last week when I saw 153!

I have also made some of my highest counts of grebes for  along time recently, today I saw at least 57 from Tern hide alone. There have also been at least 6 little egret, Walter the great white egret and as many as 193 cormorant, so life for smaller fish has been difficult, but equally there must be  a lot of them to have attracted the attention of so many predators.

Goosander Hide Highlights

The Goosander hide has been attracting people from far and wide recently, especially photographers in search of that illusive kingfisher shot. However, as is often the way, the kingfisher does not always play along, luckily it is not only a place to get kingfisher shots and we have been send a selection of great images taken from there recently by Mark Wright, here are a few of them.

There have been lots of herons around recently and they do not always get on well.

Since my observation of Walter taking a fish from in front of a cormorant he seems to have developed a limp, it could be the cormorant had a go at him as they can be quite aggressive. Hopefully he will recover  soon and continue on.

Not all the birds are large, there have been a number of grey wagtail close to the hide recently.

And not all the wildlife there is birds.

Many thanks to Mark for sending us such a great series of shots.

Birds and a (mini) Beast

As promised here are a couple of excellent pictures of the avocet that dropped into Blashford Lakes on Monday, many thanks to Keith Beswick for sending them in.

What is immediately obvious is that this is a juvenile bird, the brownish feathers would be black in an adult. Juvenile birds tend to turn up in slightly unusual places as they learn about their environment and where best to be, this one will probably join the large wintering flock in Poole Harbour.

Signs of the changing season are all around now, opening the Tern hide yesterday I saw 8 shoveler, 7 teal, a wigeon (although this was probably the bird that summered with us), a shelduck and a garganey. There were also at least 3 common sandpiper and a green sandpiper. At the end of the day the lake was dominated by fish-eating birds with at least 50 grey heron, 6 little egret, 1 great white egret (“Walter”) and 195 cormorant.

During the day I was working with the volunteers on efforts to establish a grassland in the old concrete plant site, we are making good progress and I think it will be a valuable addition to the reserve. The new path is still not open yet as the necessary agreements with our landlords are still not in place. On our way back for lunch the volunteers found a splendid caterpillar, it reminded me of Dougal the dog, a reference that will date me for those who recognise it.

The sycamore moth is rather a dull pale grey species but the caterpillar is a wonderful creature.

Reserve Visiting

I have just returned from a holiday up north where I visited a few reserves myself, but the title here refers to a visitor we had at Blashford today, an avocet. Not perhaps quite the rarity they once were, but still very unusual, unfortunately I missed it. It flew in in the early afternoon and gave good views for  a short time from the Tern hide, I am told there are pictures too, so perhaps some will make it here. I then discovered that there had been an avocet at the Trust’s new Fishlake Meadows reserve in Romsey at about 11:30 and that it had flown off heading west, it seems highly probable that these two sightings relate to the same bird travelling between the two reserves.

The one problem with going away is the number of things that have to be caught up on when you get back and the dread emails kept me in the office for a fair bit of the day, which is not to say that I did not get out on the reserve as well. The sun had brought out a few butterflies, but numbers are on the decline now. I did find a very smart comma near the Goosander hide.

Not far away I also came across a female Roesel’s bush-cricket sitting on one of our benches.

Looking from Tern hide I saw Walter the great white egret now looking very relaxed with a large group of grey heron. The herons seem not to take so much notice of him these days, at one time they would constantly be chasing him around, perhaps they have just got used to him. It is a curious thing that when little egret were first turning up they were often mobbed by gulls but now they are just ignored. Perhaps there is something about the unusual that elicits these responses and once something is regular they just become part of the scenery.

Locking up I was pleased to see that at least one of our wasp spiders is still going, I am not sure if something has predated the others or if they have laid their eggs. This one looks a though it will not be long before she lays her eggs and disappears.
