Oh, to Bee in England…

As though to emphasise the change in season today was one of those rare days when it was possible to see both brambling and swift at Blashford Lakes an opportunity that lasts for only a few days.  When I started birdwatching in the Midlands our equivalent was seeing fieldfare and swallow in the same place, on the same day. The brambling were at least 2 males at the feeders and the swift at least 14 over Ibsley Water.

Despite the remaining reminders of winter it felt very spring-like, with orange-tip, green-veined and small white, comma, peacock, brimstone, holly blue and several speckled wood butterflies seen, along with the year’s first damselfly, the large red.

After last night’s thunder storm I was not surprised that the moth trap was not over-filled with moths, although the catch did include a lesser swallow prominent, a pale prominent and a scarce prominent, the last a new reserve record, I think.

The warm weather has encouraged a lot of insects out, I saw my first dark bush cricket nymph of the year near the Centre pond. Nearby I also saw my first dotted bee-fly, this species used to be quite scarce but can now be seen widely around the reserve, although it is well outnumbered by the commoner dark-bordered bee-fly.

The wild daffodil are now well and truly over but the bluebell are just coming out.

A lot of trees are in flower now or are shortly to be, the large elm on the way to Tern hide is still covered in flower though.

Trees are a valuable source of food for a lot of insects and the find of the day was a species that makes good use of tree pollen. I had spotted what I at first thought were some nesting ashy mining bees Andrena cineraria, but they did not look right. That species has a dark band over the thorax and black leg hairs. This one had white hairs on the back legs and no dark thorax band. I took some pictures and it turns out to be grey-backed mining bee Andrena vaga, until very recently a very rare species in the UK which seems to now be colonising new areas.

They make tunnelled nests in dry soil and provision them with pollen from willows for the larvae.

The same area of ground also had several other mining bees, including the perhaps the most frequent early spring species, the yellow-legged mining bee.

Garganey!

When I opened up the Tern hide this morning I was greeted by the sight of a pair of garganey feeding just to the right of the hide. It is always a treat to see these small ducks, our only duck species that visits for the summer having wintered in Africa. They used to be called “Cricket teal” after the call of the drake, or “Summer teal” because they are about the size of a teal and come here for the summer. The only other notable birds was a another common tern, at present they seem to be adding one a day.

Later in the morning I was amazed to hear that there were now 7 garganey on Ibsley Water, some years we don’t even record a single one, clearly there had been a significant arrival of these ducks.

It has been much more spring-like in the last two days and there have been lots of butterflies seen, including brimstone, peacock, small tortoiseshell and comma in some numbers. Adder have been spotting basking by the paths north of Ellingham Drove and the great tit are nest building in earnest. Perhaps spring has finally arrived.

The last few days have been quiet, we are in an interim period, almost all the summer visitors and migrants have gone, but as yet, most of the wintering birds have yet to arrive. This reflected in this week’s sightings, a few chiffchaff remain, especially around the main car park. A juvenile ruff dropped into Ibsley Water for a day, but there are still only a few tens of wigeon around.

This does not mean there has been nothing to see though. Opening up Tern hide this week I have twice seen an adult peregrine perched on the small shingle island near the hide.

During the day on Friday the two New Forest National Park apprentices paid us a visit, they will be working at Blashford for three months from November. As it was their first visit we took a look around the reserve to see some of the areas they will be working in. The sun was out and it was remarkably warm, along the way we saw lots of butterflies, at one spot on the Dockens Water path we could see 4 red admiral, 5 speckled wood and a comma and we saw many more elsewhere along with a single peacock. There were also a few reptiles, including this very small adder, proof that they have bred successfully on the reserve again this year.

Our best sighting though was when we visited the Tern hide, there was very little to see as all there attested and the lake looked at best sparsely dotted with birds. However I glanced at the shingle just in front of the hide and realised that with the couple of meadow pipit strolling around was a woodlark, my best views ever of this species.

I will end with a plea, at this time of year rats will be spreading out looking for a good place to winter, something we do not want them to do on the reserve if we can avoid it. To this end we try not to have food lying on the ground during the autumn, we only ground feed in the late winter. Recently I have found a number of piles of bird food on logs and seats, or just on the ground as I have been going to lock up at the end of the day. This shows that the birds are not eating it, so it will be consumed by rodents overnight, potentially by rats. If any rats find enough food for them to decide to settle with us we will be unable to ground feed in the late winter when the finches are at their best. So my plea is for visitors to please not leave bird food around the reserve where rats and rodents can get to it.

 

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.

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.

Hover Bother and Getting a Goat (Monday)

After yesterday’s attempt at a picture of a flying hoverfly I had to have another go today and I got the chance on my way round to close up at the end of the day. Yesterday’s was a Syrphus species, today’s was Volucella pellucens.

The warm nights are improving things in the moth trap with catches increasing in number and species diversity. The highlight overnight was a very fresh male goat moth.

These extraordinary moths have caterpillars that eat wood by tunnelling into live trees, especially willows. As wood is not very nutritious they take several years to grow to full size.

It is also proving a good year for butterflies, with most species well up on recent years on the transects. Just now the summer brood of comma are very obvious, nectaring on bramble and just perched out in the sunshine.

Comma, this one has received some damage to the left wings.

Dragon and damselflies are also enjoying the warmer summer with good numbers of most species. The only ones that were scarce seem to have been the spring species, possibly because last year’s spring was so poor there were few to hatch this year even though the conditions were good. So far I have failed to add any new species to the reserve list, despite there being several that could wander here, especially from the New Forest. For instance there is the scarce blue-tailed damselfly, which could easily get blown in and is known to wander from breeding sites. It is rather similar to the much commoner blue-tailed damselfly, which may be one reason why we have so far failed to find one.

30 Days Wild – Day 22: Punctuated

It was thankfully cooler today which allowed us to do some work along the open western shore of Ibsley Water. As it was Thursday the “us” was the famous Blashford volunteer team. We were trimming brambles and pulling ragwort. I know ragwort is a great nectar source, but in this case we are trying to establish grassland where there has been bramble, willow and nettlebeds, this means mowing, but as we have ponies on site we need to remove the ragwort first. Ponies will rarely eat growing ragwort, but if cut and mixed in grass they will and so can get poisoned.

This shore was dominated by huge beds of ragwort and nettles but years of cutting and light grazing are taking effect and we now have mostly grassland with patches of ox-eye daisy, bird’s foot trefoil and other more desirable species. In turn this is attracting insects such as long-winged conehead.

We saw a good few butterflies including good numbers of comma. It seems they are having a very good year and the fresh summer brood emerging now is particularly strong. This generation will breed and produce another generation of adult in the autumn which will them hibernate.

comma

They get their name from the white comma-shaped marking on the under-wing, which is not visible in this shot. Their ragged wing outline makes them less butterfly-shaped and so harder for predators to find, this is especially so when the wings are closed.

I ran two moth traps last night, only about 50m apart, but one under trees and the other in the open. An illustration of what a difference location makes is seen from the number of hawk-moths caught. The one in the open contained 8 elephant hawk-moth, a pine hawk-moth and 2 poplar hawk-moth, whereas the one under the trees contained just one eyed hawk-moth.

As you will have gathered from this blog, I am a fan of insects in general, even horseflies, although I am less keen on them when they come into the office as this one did today.

It is the females that bite, so it would be better if this one went outside again.

 

30 Days Wild – Day 19: Too Hot for Walking

I was down to do a guided walk at Blashford in the morning, but it was so hot that two of the walkers cried off and all we managed was a short amble along the Dockens Water to Goosander hide. At least going through the trees by the river was a bit cooler and the Goosander hide was quite busy with a fair few sand martin coming into the nesting wall. There are also now hundreds of greylag and Canada geese on Ibsley Water, come to moult their flight feathers on the relative safety of the open water. Unlike ducks, geese become completely flightless for quite a while when they moult so they have to seek out somewhere safe, but also with accessible food.

On the way to the hide we saw a few bee orchid and several butterflies, including a couple of summer brood comma, my first small skipper of the year and a few marbled white. One of the participants on the walk told me that they are also known as “Half-mourning”, something I had not heard before.

Sometime ago I posted that we had some puss moth caterpillars, they were quite small then, but now they have grown a lot and today I was dividing them up into three groups to make it easier to keep up with feeding them. They are very fine caterpillars and get ever more so with age.

30 Days Wild – Day 14: Getting Brown

A hot day and at this time of year one when you need to take care in the full sun. I was in the office for much of the morning, which was at least cooler. At lunchtime I went outside, hoping to see some hoverflies and soldierflies on the hemlock water-dropwort, but all I saw was bees. I think it was too hot for many insects, on these kind of days they often sit out the hottest part of the day in the shade and can be found clinging to the underside of leaves.

A number of people have commented on the lack of butterflies in recent days, it is true there are not a lot, but this is not that unusual at  this time of year. The spring species have mostly finished and the high summer species are just starting, the “gap” is often bridged by lots of white butterflies, but this year they have been quiet scarce. At Blashford the mid-summer butterflies are the browns and the meadow brown are just starting to appear in numbers now. They do not bask with wings open very much once the day has warmed, up so it was no surprise that they were all sitting with wings closed today.

Meadow brown has just one generation a year and they will fly from now until early September. Some species, like small tortoiseshell and comma have two generations, with the second over-wintering as an adult hidden away out of the worst of the frost. Another of the browns, the speckled wood has three overlapping generations so can be seen from late March to early November, it can also over-winter as ether a caterpillar or a pupa.

In other news, I saw the larger of the lapwing chicks today from tern hide and it must be getting close to fledging now, as is the one remaining oystercatcher chick. The three smaller lapwing chicks seem to have been reduced to two, but they at still growing well. Out on the rafts most of the common tern eggs have now hatched and generally they seem to be in broods of three, with lots of small fish being brought in, so they are growing fast. Today many of the chicks were using the shelters to get out of the strong sunshine, over-heating can be a real problem for small chicks, so shade is important.

April Catch-up

April is flying by and we’ve been busy! We’re sorry for the rather long gap between this and the last blog, but hopefully this one explains a little of what we’ve been up to and what’s currently out and about on the reserve.

The sunshine brought plenty of visitors to our local craft event, who enjoyed the excellent refreshments provided by Nigel and Christine’s pop-up café (which will return in November) along with basket making, hurdle making and wood turning demonstrations and the chance to have a go at making bird feeders from willow.

This was swiftly followed by Wildlife Tots, who got into the spirit of Spring by making excellent nests for our cuddly birds.

We then entertained a holiday club visiting from London with den building and fire lighting activities, followed by a night walk. We’ve welcomed new six-month volunteer placement Harry, who is with us now until September and thrown him in at the deep end with a group of beavers who were here to enjoy a river dip. Luckily that didn’t put him off and Emily and the other volunteers have been busy showing him the ropes.

This week we’ve had two wet Wild Days Out, pond and river dipping in search of newts, fish and other monsters, rescuing ducks, floating boats, building dams and enjoying a balloon free water fight. Our most monstrous find was this awesome Great Diving Beetle Larva, which tried to devour anything in its sight:

Our volunteers have been super busy, with the warmer weather bringing with it the start of our butterfly transects and reptile surveys. The butterfly transects have had an excellent start, with Peacock, Orange Tip, Brimstone, Speckled Wood, Comma and Small White all recorded and Holly Blue, Green Veined White and Small Tortoiseshell also seen around. They have already recorded more than they did in the whole of April last year, so fingers crossed numbers will continue to be good!

Grass snakes and adders have started to venture into areas accessible to visitors so if the cloud disappears and the temperature warms up again keep your eyes peeled! Two grass snakes were seen recently from Ivy South hide, but out of the window at the far end rather than their usual basking spot on the log outside the front; whilst the grass verges too and from Lapwing hide are usually good places to try for a basking adder.

In bird news, Lapwing, Common sandpiper, Redshank and Little ringed plover have all been showing nicely in front of Tern Hide, along with the Black headed gulls which are getting more and more vocal! An osprey reportedly flew over the reserve on Wednesday and a Common tern was also seen on Wednesday from Tern Hide.

A Great spotted woodpecker has been busy excavating a hole in a tree trunk near Ivy Lake and best viewed from the far right hand window in Ivy North hide. Brambling were also still being spotted from the Woodland Hide this week, looking very smart as they develop their summer plumage and our first fledglings have been seen too – Robin and Dunnock – so keep an eye out for parent birds feeding their young.

Thanks to Lyn Miller and Steve Michelle for also sending in some great photos from recent visits to the reserve:

Finally thank you to everyone who’s popped in to tell us what they’ve seen, Jim and I have unfortunately been slightly office bound when not out and about leading events and group visits, so it’s great to know what’s going on out on the reserve!

We will try not to leave such a long gap between this and next blog, Bob’s back from leave soon so fingers crossed!
