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.

A Clear(er) View

On Thursday the volunteers cleared the annual vegetation from in front of the Tern hide, we do this each year for a couple of reasons. The most obvious is that it improves the view of the nearest shore from the hide. Another is that it clears the ground for the nesting lapwing and little ringed plover next spring. There are also always some seedling bramble, birch and willow that need pulling out before they get established.

Looking out from the hide today this did not make much difference as visibility was seriously reduced due to persistent heavy rain. Despite this there were some birds to see, including at least 800 sand martin, 3 swift, 2 dunlin, a little ringed plover, 3 common sandpiper, 33 mute swan and 3 pochard. Ivy Lake was quieter with just a few coot, gadwall and great crested grebe, there are also still two broods of two common tern chicks on the rafts.

Today was not a day for invertebrates, but I do have one more picture from Thursday, spotted in long grass as I went round locking up, a wasp spider, my first of the year.

A Bit of a Catch-up

Apologies for a bit of a gap in posts, a combination of not a lot to report and too much to do.

The volunteers have been busy working in and around the former Hanson concrete plant site to get it into shape for the winter and to enhance the establishment of the plantings and sown grassland areas.  I am amazed how well the planting have survived considering the prolonged dry spell we have had and the almost unspeakably poor soil they were planted into, testament to how carefully they were planted. We have also been cutting nettle, bramble and thistle growth off the areas that we want to establish as grassland such as the shore to the west of Goosander hide where we were working on Tuesday in the oppressive heat.

It turned out there was quite a lot of grass and other plants under the bramble cover, so whilst there is still a fair bit to do I think we should be able to establish a grassy bank in the longer term, ideal for wigeon in the winter and lapwing in the spring.

The warm weather has been good for insects with butterfly numbers surging in the last week.

Moth trapping has also been good with several new species for the year.

We are into a bit of a slack time for birds at the moment, although with autumn migration just starting things should pick up soon. A single green sandpiper has been around and common sandpiper reached at least six on Monday. Today there were 6 pochard, 4 more than recently. Almost all of the common tern have fledged now, just the three late broods remain, once again success has been very high at around two chicks fledged per pair. On Iblsey Water there are at least four broods of tufted duck and one of gadwall.

I had hoped to feature some of the many fine pictures I have been sent in recent days and I will do so soon, I’m afraid tonight that the technology has defeated me.

Emperors

Another very hot day and a good one for insects, hot conditions allow them to be especially active as they do not need to spend time sitting in the sun to warm up as they would on a more normal English summer’s day. I saw my first Blashford silver-washed fritillary of the year, they are regular in small numbers, but never common on the reserve.

Later I came across a pair of brown argus, these are the start of the second generation for this species this year.

Brown argus are one of the “Blues” but one that forgot this and so is not blue. The same area of grass was also hiding several stridulating Roesel’s bush-cricket, I am quite pleased that I can still hear these as they are quiet high frequency and so one of the species that slip away as we get older. If you do get to see one the pale line around the lower edge of the pronotum is an identifying character.

However the highlight of the day was none of these fine insects. After lunch I went over to Ellingham Pound to check how the common tern chicks were doing, the answer was just fine and it looks as though all seven will be flown off very soon. It is a good place to see dragon and damselflies and one of the only regular places on the reserve for small red-eyed damselfly and a quick check found one floating on some algae. I then started to look at the dragonflies in the hope of finding a lesser emperor, as there have been quite  few in the country recently and one was reported from Ibsey Water a couple of days ago. After seeing a couple of emperor dragonfly, a distinctive male lesser emperor shot past, after many attempts I got a couple of shots, not great, but I only had a 60mm lens with me!

The mainly dark abdomen with pale blue “saddle” is what identifies it. As I waited for it to skim past again I inevitably snapped other dragonflies too, when I looked at these pictures later I think one of them shows a female lesser emperor.

The lesser emperor is a migrant from the south, it used to be regarded as very rare but is getting more common, especially in warm summers and certainly tries to breed here now. It seems it is another species that is trying to colonise thanks to warming temperatures. The Odonata (dragonflies and damselflies) seem to be especially responsive to these changes with many species spreading across Europe dramatically in the last couple of decades.

Elsewhere on the reserve there were at least three common sandpiper on Ibsley Water where there was also a juvenile little egret and, at the end of the day, 3 adult yellow-legged gull. I also found that the pair of Mediterranean gull on Long Spit had managed to fledge a single chick, or at least I could only find one. Although they have nested with us before I cannot be completely certain they have raised a chick to flying on Ibsley Water previously.

Hopefully it will cool down a bit next week and I can get some of the paths trimmed, they certainly need it! I had intended to try today but it was just too hot.

It’s Good to have a Hobby

And even better to have two! Which is what we saw today hunting insects over Ivy Lake when we went to put out another of the tern rafts. These sickle-winged falcons winter south of the Sahara and fly north to breed along with their favourite prey, swallows and martins. Watching them swooping to catch flying insects is a fantastic experience, you can only marvel at their mastery of the air, one of the great sights of summer.

The tern rafts are gradually being deployed, so far the terns have looked interested but failed to occupy any of the rafts before they have been dominated by pairs of  black-headed gull. It is always a problem getting the timing right and this is why I deploy the rafts one or two at a time, at some point the terns must surely be ready to take control of one.

There have been at least 30 common tern around regularly and they have been doing courtship flights and bringing food, so I think they should be ready to settle soon. So far there has been little sign of much tern passage, apart from a few beautiful black tern, the biggest group so far being 5 on Sunday afternoon. Little gull are usually birds of passage that stay at most a day or so , which makes the fine adult that has been frequenting  Ibsley Water for several days something of an exception. It was there again today, although I don’t think anyone saw the Bonaparte’s gull. Other birds have included a few dunlin and common sandpiper and last week a bar-tailed godwit.

In recent posts we have featured a number of pictures of lapwing chicks, sadly I don’t think any of them have survived. This season has been a good one for the number of pairs and in general hatching success has been quite good, but the chicks have been disappearing fast. I think a combination of dry weather and predators is the cause. Dry conditions mean the chicks get brought to the lakeshore to seek food, as all their favoured puddles are gone, unfortunately the shore is regularly patrolled by fox and other predators, as it regularly has washed up food in the shape of dead birds and fish. The foxes may not be actively seeking the chicks but they will not refuse one should they come across it. Sadly a similar lack of success is befalling the little ringed plover, but at least they will continue to try and may yet succeed before the summer is out.

The cold winds are making moth trapping a slow business, with few species flying, although we have caught an eyed hawk-moth and a couple of poplar hawk-moth recently.

A Dry Spring

Lots of visitors are coming to the Tern hide at present, drawn in roughly equal measure by the Bonaparte’s gull and great views of the lapwing chicks. The gull was present on and off again yesterday as were 3 little gull (2 of them beautiful adults), up to 27 or more Mediterranean gull and at least a dozen common tern.

The two lapwing chicks in front of the hide are doing well and approaching two weeks old now, this is especially pleasing as they are only protected by their mother, dad having gone missing a while ago. She is driving off all comers, but especially redshank, common sandpiper and little ringed plover, not perhaps the greatest threats to her chicks.

So far lapwing are having a remarkable year and we have something like 20 pairs nesting with at least five already hatched. Of these three can be seen from Tern hide. The lake shore has the lure of water, where the chicks can find small insect prey, but it is not that safe as it is frequented by many predators. They would be better staying around puddles away from the shore, but the recent long bout of dry weather has meant almost all of them have dried out now, we could really do with some rain!

The good weather has been brilliant for early butterflies though; the reserve has had lots of orange-tip and large first broods of speckled wood and small copper.

As spring moves on we are now entering “Willow snow” season, when the woolly seeds of the willows are blown around and collect in drifts. It is these light-weight seeds that allow willows to colonise so well as they are carried long distances by the wind.

Despite the dry weather there have been a few fungi around and I came across the one in the picture below growing on lichen heath on Sunday, I have failed to put a name to it though.

Recent days have seen a good range of birds around the reserve. Both garden warbler and common swift have arrived in numbers and there has been a good variety of migrants. On Sunday a fine male ruff was on Ibsley Water and other passage waders in the last few days have included whimbrel, greenshank, dunlin and common sandpiper.

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!

Walter Returns!!

I am delighted to say that I was wrong to suggest that we might have seen the last of our returning great white egret “Walter White” as today he appeared, way beyond his usual return time but here none the less. It was good to see him back at about 13 and a half years old he is a grand old bird now.

A rather distant Walter but with his distinctive set of rings, so we know it really is him (you can’t see the rings in this shot though).

It was actually quite a good day to be looking at birds on the reserve today. When I arrived Ibsley Water was alive with house martin, at least 1500 by my estimate and lots perching in the bushes around the main car park too.

During the afternoon there were 3 garganey on Ibsley Water, they spent a good bit of their time well out in the centre picking insects off the surface, it seems that they were first seen on Friday, although not noted yesterday. Other ducks were few in number but included a pochard, shoveler, wigeon and teal. There were also still 2 ringed plover and 2 dunlin as well as single common sandpiper and green sandpiper. It was also a good day for birds flying over with red kite, peregrine, raven and marsh harrier being seen. We also saw the first common gull of the season as well, despite their name not usually a common bird at Blashford. Perhaps even more surprisingly, the most unusual record of the day was probably a female house sparrow in the bushes beside the Main Car Park.

In the morning there was a volunteer working party, we were working on the grassy bank near Ivy North hide, mending the fence and digging out Turkey oak saplings. This is an interesting area and gets very warm as the bank faces south and is angled at about 30 degrees, as the sun warmed up we counted at least 5 small copper butterflies.

A Late Surge

It was a generally grey, humid day with very little to report. A yellow wagtail and a spotted flycatcher seen at the Tern hide in the morning seemed like the best the day had to offer. Despite the warm night even the moth trap was not exactly exciting, the best being a large haul of largely unidentifiable (at least to me) caddisflies and a female bulrush wainscot.

As usual the Tern hide was locked up last and Tracey came over to take a look , just in case there was anything to see. At first the best was a single common sandpiper, after a while we realised there were two, then I spotted a wader flying about over the water, at first I could not work out what it was then, the give away, it landed on the water – a grey phalarope. I have missed a couple at Blashford before so I was pleased to see this one, I tried to get a very distant picture and the result is probably the worst bird picture ever to grace this site, and that is saying something! If you use  a lot of imagination you might be able to see what it is.

Apart from this the lake was very quiet, even most of the tufted duck seem to have gone now. As I watched the phalarope it swam passed a sleeping duck and it dawned on me that it was a drake common scoter! I did try a picture but this one was so bad that I won’t distress you with it. Good things can come in threes, but despite looking hard we could find nothing else , apart from a third common sandpiper.

It just goes to show that just because there does not seem to be anything much around it is always worth taking a good look.

One Day, Two Reserves

I am not often at Blashford on a Saturday, but this weekend I was, I managed to intersperse catching up on paperwork with a walk round all the hides. Getting around the reserve is very pleasant but also highlights all the tasks that need planning into the coming winter season, I think an eight month winter would just about be enough!

Opening up the hides I saw a greenshank and three wheatear from the Tern hide, which suggested that there might well be migrants about and with luck “something” might turn up.

As usual the day proper started with a look through the moth trap. This contained no rarities but one unexpected moth, a very fresh dark form coronet, this is an attractive moth and one we see quite often, but it flies in June and July. If I was to get one at this time of year, I would have expected it t be an old, battered one on its last legs, not a pristine newly emerged one.

The cumulative results of my wanderings throughout the day indicated that there were indeed a reasonable scatter of migrants around the reserve. Chiffchaff were frequently to be seen, although willow warbler were many fewer than last week. In one mixed flock of birds near the Lapwing hide I saw a very smart juvenile lesser whitethroat, a rather rare bird at Blashford these days. On the south side of the main car park a spotted flycatcher was catching insects from the small trees and there were several blackcap eating blackberries.

In the early afternoon I was in Tern hide when I spotted an osprey in the distance flying towards us down the valley, it looked as if it was going to come low over Ibsley Water, but as it came over Mockbeggar North lake a large gull started to chase it and, rather than brush off this minor irritation, it gained height and headed off at speed to the south. It was a young bird and is going to have to learn to tough out such attention.

It was not a bad day for insects, I saw red admiral, painted lady, small white and speckled wood, despite almost no sunshine and there were good numbers of migrant hawker and brown hawker about. I also saw more hornet than I had noticed so far this summer and very widely about the reserve too.

Other birds of note were mostly signs of approaching autumn, a single snipe near the Lapwing hide was the first I have seen since the spring here and later wigeon, one on Ivy Lake and 4 on Ibsley Water were also the first returns that I have seen.

For a couple of years now I have been noticing increasingly large floating mats of vegetation in the Ivy Silt Pond and kept meaning to identify the plant species involved. I finally did so yesterday and one of them, the one with the rosettes of pointed leaves, is water soldier, a rare plant in Hampshire and mostly found on the Basingstoke canal!

water soldier

It is probably most likely to be here as a result of escaping from a local garden pond, but might be wild, anyway it seems to be a notable record and as far as I know it has not been recorded here before.

In the evening I went out to another reserve in my area, Hythe Spartina Marsh, it was close to high water and I was interested to see if there was a wader roost. There was, not a large one but interesting, it included 74 ringed plover, 30 dunlin, 2 turnstone, 3 grey plover and a single juvenile curlew sandpiper. In addition 2 common sandpipers came flying north up  edge and on the way across the marsh I saw a clouded yellow butterfly nectaring on the flowers of the sea aster. I also saw that on e of the juvenile ringed plover had got colour rings on its legs, however it would only ever show one leg so all I could see was a white ring above a red ring on the left leg, not enough to identify where it had come from. Ringed plover can breed locally on our beaches or have spent the summer way off in the high Arctic of Canada, so it would have been good to see all the rings.
