Summer Passing

It seems that once the 30 Days Wild are over, the signs of passing summer become increasingly obvious. I heard my last singing cuckoo on 22nd June, we now know that many will have left the country southward by the end of June, thanks to the advent of tiny satellite trackers fitted to some birds by the British Trust for Ornithology (BTO), you can follow their progress via a link on their website.

At Blashford Lakes common sandpiper are returning and on Sunday there was a greenshank, returned from breeding, probably in Scandinavia. Lots of the swift have left already as have the first generation of young sand martin. Over at Fishlake Meadows an osprey is being seen regularly, with other sightings including up to six cattle egret.

Around the reserves we are now at the peak of butterfly numbers, with lots of “Browns” especially.

This week will probably see “Peak-gatekeeper” and we may have just passed peak-meadow brown. Speckled wood, by contrast are perhaps the only butterfly with a real chance of being seen throughout the 26 weeks of the butterfly recording season as it has continuously overlapping broods.

In places you may notice a few very dark, almost black, meadow brown, actually these may well be ringlet, with slightly rounder wings and multiple eye-spots.

Several species now have their summer broods emerging, this is true for common blue, brown argus, small copper and peacock.

The warm weather has been great for insects in general, there have been good numbers of dragonflies, including a single lesser emperor, a formerly very rare migrant species that seems to be getting ever more frequent.

Summing up…

The past two weeks hasn’t all been about the current improvements at Blashford, we have been in search of reptiles and amphibians on two Wild Days Out, run a busy family pond dip session (distinctly lacking in newts, we must have scared them all off the week before!) and woven some very pretty Easter baskets using materials found on the reserve.

And the reserve is looking lovely! It is getting greener by the day, although some trees are suffering more than others from the ever increasing number of munching Alder leaf beetles. This Crab apple in particular is being stripped bare:

There are plenty of wildflowers out, including Germander speedwell, Ground ivy, Cuckoo flower, Moschatel, Primrose, Cowslip and Common Dog-violet. Lesser celandine is carpeting the woodland floor near the reserve entrance and the Bluebells will soon be following suit, with some already flowering.

The warm sunny weather has bought the butterflies out in force, with Brimstone, Orange-tip, Speckled wood, Small white, Comma and Peacock all on the wing.

Large numbers of Sand martin have been investigating the holes in the Sand martin wall in preparation for nesting and Swallows are also back, although currently in much smaller numbers. Three Black tern spent most of today over Ibsley Water and as I left all three had alighted the Osprey perch out in the lake. Little ringed plover have been on the shoreline and Lapwing continue to display overhead.

If you have visited recently and would like to share your wildlife sighting with us, please do email them to BlashfordLakes@hiwwt.org.uk along with whether you are happy for us to use them on the blog and on other promotional material and how you would like to be credited. We don’t always manage to post images straight away, but do always enjoy seeing them, so thank you David for sharing these.

The woodland is full of bird song, with Chiff-chaff and Cetti’s warbler in particular standing out with their more striking calls. Blackcaps are seen frequently although they do not stay in one spot for long and Willow warblers are also present whilst Brambling and Reed bunting continue to feed in front of the Woodland Hide. Sedge warbler and Reed warbler can also be heard in the reedbeds by Ivy North Hide and Ivy Silt Pond.

Brambling

And finally back to the events! On our Wild Days Out Amphibian and Reptile Rambles we managed one young grass snake, the same snake in the same spot on both days. This really isn’t the best photo, but if you look in the centre you might be able to make out the tip of it’s tail as it disappeared into the undergrowth.

Spot the tiny grass snake’s tail!

On both days the weather was fairly cool so we failed to spot an adder, but both groups enjoyed a longer walk over to Goosander Hide and the older children managed to make it as far as Lapwing Hide.

Back at the pond we had more success, catching a number of newts, and we also found some under the logs in the woodland. Both days were enjoyed by all, even if the reptiles were a bit thin on the ground!

And last but not least, on Wednesday morning a very satisfying two hours were spent weaving in willow wood, with a number of children creating some very striking Easter baskets using materials collected on the reserve and a wooden disc base prepped by volunteer Geoff. We used rush, sedge and larch as well as the willow, with a couple of the older children even having a go with fresh bramble. One of the girls stripped the bark off some of the willow leaving the inner white of the rod on show. They all looked amazing!

The last couple of weeks have been very varied, but with the weather warming up it has been lovely to be out and about on the reserve. Spring is definitely here!

Open Again

The Tern Hide will be open again today, although there are still some access restrictions elsewhere on the reserve, where works continue, please take note of any signs as works are changing day by day as they are completed. That said all the hides are open, as is the Centre.

The last few days have been as hectic as have many over the last few weeks, although thankfully we are firmly on the home stretch now. Despite a degree of chaos spring is definitely moving along apace.

Chiffchaff and blackcap are now present in good numbers and we have also have the first reed warbler and willow warbler on the reserve. Over Ibsley Water large numbers of sand martin, house martin and swallow have been gathering and some sand martin are now visiting the nesting wall. There have also been migrants passing through, the week has been characterised by a significant movement of little gull, with up to 12 over Ibsley Water at times, on their way to breeding areas around the Baltic Sea.

A proportion of the swallows and martins will be moving on as will be the splendid male yellow wagtail that was seen on Thursday.

Insect numbers are increasing also with many more butterflies around.

As well as the species that hibernate as adults there are also lots of spring hatching species too, particularly speckled wood and orange-tip.

The nights, although rather cool have more moths now, on Friday morning the highlight in the moth trap was the first great prominent of the year.

Earlier in the week a red sword-grass was a notable capture, possibly a migrant but also perhaps from the nearby New Forest which is one of the few areas in southern England with a significant population.

I have also seem my first tree bumble-bee of the year, a queen searching for a nest site, this species only colonised the UK in the last 20 years, but is now common across large areas.

Of course all the while resident species are starting to nest, blue tit and great tit are starting to lay eggs and I have seen my first song thrush fledgling of the year. Out on Ibsley Water lapwing and little ringed plover are displaying, truly spring has arrived at Blashford Lakes.

Bee is for Blashford

Or maybe Blashford is for bees, well of course it is! Blashford is for all wildlife and the people who like to experience it. Everyone knows the honey bee and bumble bees, although perhaps not that there are 28 species of them. However there are something like 250 other species of bees in Britain and they all spend their days visiting flowers and pollinating them. These 250 are the so called solitary bees, despite the name they can occur in great aggregations, importantly though each nest is the domain of just one female, there are no worker bees.

There has been much coverage recently about the declines in insect numbers around the world and that of pollinating insects in particular, perhaps because they are economically important to us as pollinators of crops. Declines could be for many reasons and probably are multi-factored, but a general loss of habitat and an increasing uniformity in what is left, along with increased prevalence of chemical contaminants are all likely contributors. Some enlightened local authorities are modifying their grass mowing regimes on verges, roundabouts and recreation site to allow more flowering, some of the best are actually seeding back wildflowers or using “meadow mixes”. In fact we can all help by providing flowers that are good sources of nectar and by valuing some of the “weeds” that we might have removed in the past. For instance a lawn with dandelions may not win the green-keepers prize but these are a very important source of food for early flying bees and hoverflies.

Blashford Lakes has lots of nectar sources, especially at this time of year when willows are important for many species and so has lots of solitary bees. Many also need bare, sandy soil to dig their nests and we have that in abundance too.

One of the problems with solitary bees is that some species are very similar to one another and so difficult to identify in the field. Although the grey-backed mining bee female is distinctive the male looks very like the male of another species, the ashy mining bee.

One of the commonest mining bees around at present is the yellow-legged mining bee, which can be found nesting in bare ground in banks, lawns and various other places.

Andrena flavipes male

yellow-legged mining bee (male) – or at least I think it is!

Some bees are neither colonial nor make their own solitary nests, they are nest parasites of other bees. One genus of bees the Nomada bees specialise in this way of life, often specialising on one particular host species. The yellow-legged mining bee plays unwilling host to the painted nomad bee, which looks very wasp-like.

The last few of days have seen big arrivals of hirundines, Monday was almost all sand martin, yesterday there were a few swallow and the odd house martin and today there were even more swallow, probably over 50. On Ibsley Water there a couple of pairs of oystercatcher, a pair of redshank, probably five little ringed plover, several lapwing and today two green sandpiper. Meanwhile around the Centre and Woodland Hide the wheezing of brambling is very much in evidence, particularly in the morning, there are at least 30 and I suspect 50 or more around just now.

And remember it does not take much effort not to mow the lawn for a few days and let the dandelions flower to feed the bees. You could put your feet up and have a cup of tea, or a beer (other drinks are available), whilst making your own contribution to Wilding Hampshire!

Some Birds and Some Bees

I had my first proper look out of the new Tern Hide when I arrived to open up this morning and was greeted by something between 600 and 1000 sand martin swooping over the water, the first serious arrival of hirundines this spring. I saw only one swallow though and no sign of any house martin.

Along the shore in front of the hide there was a pair of little ringed plover and a fine male lapwing.

There were several ducks feeding close in too.

I spent a good part of the day trying to complete the annual report, which kept me in the office on a day when outside would have been far preferable. However I did have an excuse to get out for a while and enjoy the sunshine as we had a visit from a small group of top entomologists to look particularly at solitary bees, of which we saw many species including a few new reserve records. Incidentally we also saw several orange-tip, including one female, speckled wood and peacock.

Locking up the weather was still sunny and at the Woodland Hide finches were still feeding, including a good number of brambling.

There were also several reed bunting, almost all males.

Bittern not Stung

I am fairly sure that the bittern that spent a good part of the winter showing off by Ivy North Hide left on the night of Sunday 17th March, conditions were perfect and there were no records in the next couple of days. However a couple of brief sightings in since suggested I was wrong. This evening I saw a bittern from the hide, but it was not the bird that wintered there, being somewhat duller and, I think, smaller. This may be the second bid seen during the winter but which was chased off by the regular one, now able to hunt in peace, or perhaps a migrant.

The sun was warm today, although the wind was a little chilly. In shelter there were lot of insects about, I saw peacock, brimstone and small tortoiseshell and probably thousands of solitary bees. I was able to identify a few species, the commonest was yellow-legged mining bee then the grey-backed mining bee, nationally a very rare species, but abundant locally at Blashford Lakes. The only other I certainly identified was red-girdled mining bee. It was pleasing to see lots of female grey-backed miners as I had been seeing what I was convinced were males for several days, but they are very similar to the males of a commoner species, the females are much more distinctive. My first female was sunning itself on the new screen I was building beside Goosander Hide.

I later went to see if there were any around the sandy bank we dug for bees a couple of seasons ago and there were, loads and loads of them!

The sound of the masses of bees was amazing, there really was a “Buzz in the air”, although solitary bees can sting they do not often do so and the vast majority of the bees around the bank were males, which have no sting, so it is possible to enjoy the experience with little risk.

I had the first report of sand martin at the nesting bank today, hopefully we will have a good few nesting pairs again this year.

Elsewhere reports of a glossy ibis at Fishlake Meadows was impressive as was that of a white stork very close by at Squabb Wood, Romsey

Nearly Re-Terned and Last Pop-up

We are nearly there, the Tern Hide reconstruction is getting close to completion. The structure is up, although the roof still has to be finished, then there are the banks and screens to put up and various other finishing elements to do, but we are nearing the end now. The project has not just been about the Tern Hide though.

There is a great new viewing platform on the bank to the rear of the main car park, which gives a fantastic view, not just of Ibsley water but a panorama of the whole valley, it could become a great place to watch migration.

Over at the Education Centre we have a new information hut and a second education pond, this is will allow us to reline the existing one which leaks badly, without having any time without a pond. There are also various other improvements to the lay-out that should make it much easier and safer for education groups and visitors as a whole.

Further out on the reserve there will be new signage and one or too surprises too. If you have not visited for a while you may also notice that we have done some further tree felling, this has been targeted at invasive Turkey oak and grey alder, in both cases removing these will allow space for more native trees to grow. Although the landscape value of such non-native trees can be positive, they harbour markedly less wildlife.

Although we are approaching the end there are still some restrictions in places, most notably the car parking at the Centre, which is being re-levelled and surfaced, please take notice of signage and temporary fences whilst this work is going on.

This work has been made possible thanks to a grant from the Veolia Environmental Trust.

vet-logo

Despite all this work we have remained open for business as close to normal as possible. The bittern has been parading about, although it seems likely it has now departed. The ring-billed gull has been roosting on Ibsley Water, where there has also been a very fine drake garganey. At Woodland Hide there have been small numbers of redpoll and brambling among the chaffinch, goldfinch and reed bunting. On top of all this there are migrants arriving in moderate numbers with at least 27 sand martin yesterday and also blackcap, chiffchaff and little ringed plover.

This weekend sees the last appearance for the season of the Pop-up cafe, so if you do not make it to the reserve you will have to wait until next autumn for some of the best cake around.

Spring is all around with insect numbers increasing, numbers of moths have been rising and last night we saw our first brindled beauty of the year, following on from our first streamer and engrailed earlier in the week.

Numbers of solitary bees have been increasing too, including lot of what I think are male grey-backed mining bee, this is a very rare bee and the males are very similar to the much common ashy mining bee.

And Wildlife Too

Although the week on the reserve was undeniably hectic with contractors working away all over the place, it was still a week of wonderful wildlife.

The early surge of migrants dropped off when the wind and weather changed, but as we get into mid-March migrants are arriving anyway. Chiffchaff are now singing at various locations, sand martin are being seen occasionally and a little ringed plover has been a fixture on Ibsley Water, although hard to find hunkered down out of the wind.

Perhaps the most surprising bird on the reserve has been the bittern, which seems not to want to leave and has been giving good views day after day from Ivy North hide.

The bittern remains lurking and often not, near Ivy North Hide

The adult ring-billed gull seems again to have become a regular fixture in the gull roost on Ibsley Water each evening, after having gone off somewhere or the mid-winter period.

The early butterflies have retreated due to lack of sunshine, but the occasional adder is still being seen and mild nights have resulted in good moth catches. Common Quaker are most abundant, but Hebrew character, small Quaker, twin-spotted Quaker, clouded drab and oak beauty have all been regular. Although not warm enough for butterflies, bees are made of sterner stuff. Buff-tailed bumble-bee queens are buzzing around and investigating potential nest sites between bouts of feeding, sallow catkins being one of their favourites.

There are also some solitary bees flying, so far only males that I have seen, they tend to emerge earlier than the females. Yellow-legged mining bee being the most common, but I found a blacker bee this week, I suspect it of being the rare grey-backed mining bee. The female is very distinctive but the males look similar to the much commoner ashy mining bee.

The wonderful thing about spring is that you can see the things moving on day by day, even when the weather is poor, the imperative to get on with life pulls wildlife along, or perhaps pushes it. The costs of being late are probably to miss out on breeding, so this encourages getting earlier to steal a march on rivals, but get it wrong and starting too early and all can be lost.

Climate change is an added complication at this time of year when timing is so important and the costs of getting things wrong so high. Many species respond to temperature, but others to day length, or other factors or combinations of them. Many species will be dependent upon on another, bees need flowers for food but the plants need bees to pollinate them, sometimes the relationships are complex and the interdependence critical to survival. If the relationship is broken completely extinction is likely for one or both partners, but even stretching it will result in declines.

There is no doubt that our management or mismanagement of land, use of chemicals and casual approach to waste have all taken a serious  toll, the much publicised insect decline being just one result. We are now recognising some of this and some things have been turned around, ozone in the atmosphere being a good example of effective action.

However the really big threat is climate change and it will not be so easy to reverse, in fact halting it looks way beyond us at present. So it was really refreshing to see so many young people getting involved in a call for real action, showing that there is perhaps a generation who are seeing the big picture. The lack of engagement by the young in politics is often decried but maybe they are seeing what others are missing, the real issue is way beyond politics and certainly our current politicians. The environment not as special interest, but a matter of life and death.

 

Some Things are Hard to Swallow

A rough day on the reserve today, but despite this there were reports of at least eight sand martin over Ibsley Water, so Spring migrants are still arriving. I missed seeing the martins but did see a little ringed plover. Other birds today were a small flock of black-tailed godwit which flew over, a single dunlin, the black-necked grebe, now in breeding plumage and a brambling. The bittern continues to be seen at Ivy North Hide, it is getting very late for it to still be here. At the end of the day it was sitting hunkered down in the reeds near the hide, looking miserable after a wet and windy day.

It did not look as though it was interested in anything other than keeping out of the wind and rain, however something caught its attention.

What was that?

It certainly seemed worth investigating.

Having made the capture the next trick is was to manoeuvre it into a swallowable position.

It then stalked off, passing close to the hide to spend the night digesting, I would guess it won’t be flying off tonight so should still be around for at least another day.

A cracking way to end the day!

Things Moving On

The unseasonably warm weather has yet to produce any summer migrant birds at Blashford, although elsewhere in the country there have been multiple sightings of swallow, sand martin and house martin, a swallow has even reached Shetland! We do have lots of signs of spring though, the wild daffodil are coming out in numbers, especially near the Woodland Hide and the moth trap is turning up some species more typical of March than February.

Things are also moving on with the various works on the reserve and are likely to pick up further next week. The new Centre pond is almost ready to receive water.

Some things don’t seem so keen to move though, the bittern remains regularly seen outside Ivy North Hide, at times showing very well.

The other notable heron species that had been seen regularly there, the great white egret does seem to have made the move though, with no sightings in the last few days. My last known sighting of “Walter” the colour-ringed egret was last Saturday, I am guessing he has returned to France for the summer.
