30 Days Wild – Day 29: A Grave Day

Luckily not as bad as it sounds, in fact actually a “Jolly”. Each year the volunteer team have a day out at Kitt’s Grave, it is part of the Martin Down National Nature Reserve but belongs to the Wildlife Trust. Although it is managed by Natural England we usually go up top do a couple of tasks each winter, although we did not make it last season. We have been assisting in the clearance of scrub to open up glades and ultimately restore areas of chalk grassland. As we have been doing this for some years it is interesting to see how the habitat has been developing, I am pleased to say that the answer is well so far.

Our visits are usually a great chance to see lots of butterflies, but as we left the car park this morning we were wondering if we would see any at all. Luckily we had a good start in other ways, with a turtle dove purring away in the thorns. Crossing the road to Kitt’s Grave we heard a lesser whitethroat and heard and saw yellowhammer and corn bunting. Then a surprise, a ringlet, then more and marbled white, small skipper, meadow brown, small heath and even dark green fritillary. Although it was overcast it was warm enough for insects to be active, but not so warm that they were too flighty, this allowed a great chance to get really good views as they basked in an attempt to get warm.

The marbled white were especially numerous and lots of the females were egg-laying.

I noticed one small skipper below a pyramidal orchid flower spike, at first I thought it was sheltering, but it did not look right, then I realised that it was actually in the jaws of a crab spider, ambushed as it was trying to get warm, or maybe feeding. Luckily not all of them had fallen victim to predators.

We also saw silver-washed fritillary, but the most surprising butterfly seen was a purple hairstreak, picked up off the path, but which flew off before a picture could be taken. Although we never saw the sun we did see a common lizard, sitting out in the hope of catching a few rays. As we always do and despite unpromising conditions we had a great time and saw a lot of wildlife. Martin Down is a magical place to go and a reminder of what large parts of the southern chalk must once have been like.

30 Days Wild – Day 26: In the Woods

A day of meetings for me today, but at least one of them was in a woodland on a small reserve where we are looking at some works to rejuvenate a mire that is getting shaded out by willow, birch and pine. The area has a lot of fallow deer and although we saw only a couple of adults we found two fawns lying up in the bracken.

There were a few butterflies out including meadow brown and ringlet, but it was reptiles that stole the day. We saw a very large female grass snake and as we were leaving a fine male adder.

I had to wait until I got home to see my other highlight of the day, when I checked the moth trap it contained a small elephant hawk-moth, one of my favourite species.

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.

Mothless, well Almost

Yesterday I ran a “Moth event” at Blashford, unfortunately I forgot to tell the moths and there were probably more human participants than moths! Usually late August is a good time for catching large numbers of moths, but big catches require warm, calm nights following warm settled days. What we had was a windy, mostly clear night following a rather stormy day.

Luckily the day got more settled as it went on, at least until late afternoon anyway. This brought out good numbers of insects, including as many dragonflies as I have seen this year. Around the reserve I saw several brown hawker, southern and migrant hawkers, an egg-laying emperor dragonfly and a fair few common darter. Damselflies included common blue, azure, red-eyed, small red-eyed and blue-tailed.

Butterflies were rather fewer, most that I saw were whites, with all three common species near the Centre. Out on the reserve a few meadow brown and gatekeeper are still flying and speckled wood are increasing again. Near the Lapwing hide I saw both red admiral and painted lady, perhaps indicating some continued arrival of passage insects.

The sunshine in the middle of the day brought out reptiles as well and I saw two grass snake and an adder. The adder was very fat and I suspect a female which will shortly be giving birth, since adders have live young rather than laying eggs as grass snakes do.

I have heard reports of wasp spider being seen around the reserve recently and today I finally saw one.

This is a female, the males are much, much smaller and wander about seeking the females.

I had hoped for a few different birds, following the rough weather, perhaps a few terns, but there was little change form the past week. A few extra waders were the best that could be found, 2 dunlin, 2 oystercatcher, 2 common sandpiper, 1 redshank and the pick of the day, 3 greenshank, although they only flew through. There are starting to be a few more ducks around, I saw 8 shoveler and 3 teal, but there are still no wigeon on the reserve, although they should not be far away. Away for the water looking up there were 2 raven, and single hobby and peregrine. Whilst low over the water before the day warmed there were 1000+ sand martin and c200 house martin.

Perhaps the sighting of the day for many visitors though was the female roe deer that spent part of the morning in front of the Woodland hide.

Remaining Wild

A bit of  a lull for a couple of days due to computer problems, perhaps now sorted? But only time will tell.

Over the last couple of days, and say this quietly, it has been rather more summery. Although it is clearly already moving into late summer as many migrant birds are on the move, starting their southward journeys. On Ibsley Water there are returning common sandpiper, at least two on recent days, also a fine male black-tailed godwit yesterday, returned from trying to breed in Iceland. There have also been large gatherings of sand martin stopping to feed on their was south to Africa for the winter, likewise I suspect that some of the swift are on the move too. The cuckoo have stopped “cuckooing” and most will be gone, just the juveniles left to give us records into autumn. Although the blackcap still sings it is now the late summer song, which is subtly different form their spring one, still recognisably blackcap, but with  a more melancholy sound.

It is not all downbeat though, lots of butterflies are coming out, “Brown season” is in full swing with loads of meadow brown and marbled white (they are browns really, honest) and the first gatekeeper too. It is also getting towards peak horsefly season, okay perhaps not such a cause for celebration, but most species do not bite humans. Today I came across one such species Hybromitra distinguenda, also known as the bright horsefly. It was also a male, so no risk at all of being bitten as it is only the females that bite. He was hovering at about 75cm, swinging from side to side and back and forth, above the track to Ivy South hide as I went to open up. I have seen other Hybomitra species doing this, sometimes as early as 06:00am and often in small groups, I assume it is some sort of display to attract passing females, but I have never seen a female fly in. Here are a couple of pictures I managed to grab.

Horseflies are remarkable creatures, they are probably the fastest of all flies, capable of 30 or 40 kilometres per hour and incredibly manoeuvrable being able to make a 180 degree turn in just a few metres, even at that speed. They have huge eyes that give them close to a 360 degree view of the world and a visual processing speed that makes catching them fantastically difficult unless they are not paying attention.

 

30 Days Wild – Day 27

Up and out early today to do my final breeding bird survey of the year, in fact not quite as early as I had hoped as it was rather drizzly at dawn, but still in the field by 05:40. I am surveying a site about 40 minutes from home so there is always a risk that conditions are okay at home but not at the site.  As it is now quite late in the season a lot of birds have stopped singing and some have completely finished nesting and are wandering around in flocks. In this regard the rather wet conditions of late are an advantage as this enables many resident species to have an extra brood, species like song thrush and blackbird, will give up in June in a dry season but can often have an extra brood if worms are still easy to come by in a wet season.

I did have quite a few singing thrushes and also a lot of wren and the summer visitors are still mostly singing so chiffchaff and blackcap were in good numbers. I also had several young birds, some being fed by their parents, confirming breeding. The survey involves mapping the location of every bird seen or heard on eight to twelve visits. This can then be analysed to give a fair estimate of the number of territories of each species present. All I have to do now is transfer all the data to species maps and work out how many territories of each species I have found, it could take a while!

For almost the whole of my four hours on site it was grey with low cloud, but just as I finished the sun came out and with it lots of insects. I saw meadow brown, marbled white, large skipper and small tortoiseshell in just a couple of minutes.

Almost next to the butterfly on the same bramble there was a very smart longhorn beetle, with a very long-winded name, it is the golden-bloomed grey longhorn beetle Agapanthia villosoviridescens.

My afternoon was spent in a meeting at County Hall, Chichester, a pretty wildlife free zone, but as I left the building it was great to hear the cries of the peregrine on the cathedral, probably the young ones after food from their parents. It is amazing to think that about forty years ago these birds were restricted to western cliffs and that they were plagued by the twin ills of egg collectors and pesticides to the point where it seemed we might lose them altogether.

 

3o Days Wild – Day 23

Another Thursday and we decided to tackle what is without doubt the volunteers least favourite task of the year, ragwort control around Ibsley Water. When I first started at the reserve ragwort was the dominant plant around large areas of the shore, often to the exclusion of all other plants. Over the years we have cut and pulled it to try and establish a more mixed and predominantly grassy sward. It has been back breaking work, but it finally seems to be paying off. Walking the eastern shore it is now no more that occasional and forms part of an increasingly varied sward including sedges, bee orchid and much more.

Ragwort is actually a valuable nectar source and present in small amounts in grassland that is not used for hay does not present any real risk to livestock. Although poisonous few animals will eat it when growing. Fortunately at Blashford the grassland has many other nectar sources so loss of some ragwort  probably has minimal impact upon nectaring insects. As we worked we saw a good range of butterflies, despite the overcast conditions including lots of meadow brown.

I also saw my first small skipper of the year, although a few have been seen on the reserve by others.

The day was not entirely positive though. Arriving at the reserve and looking out onto Ibsley Water it was clear that the black-headed gull pairs with chicks and single common tern pair that had just started sitting on the small island neat Tern hide had been lost overnight, probably to a predatory mammal. Fox is probably likely, but they often get the blame when others are actually the culprit and I cannot rule out badger, mink or otter.

I got a real surprise at the end of the day when I closed up the Tern hide I realised there was a female common scoter floating around with the tufted duck flock. There was also a black-necked grebe reported in the hide diary, although I could not find it.

 

 

30 Days Wild – Day 19

Sunday and almost mid-summer and I was at Blashford where we were hosting Fordingbridge Astronomical Society’s Sun Day. They had telescopes set up so that the sun could be safely viewed and some of its usually hidden secrets seen. However, the clouds did not play along and the sun remained hidden resulting an early end to Sun Day.

However Sunday continued and in the afternoon I was leading a walk to look for dragonflies, damselflies and miscellaneous other bugs. Unfortunately the clouds had continued to gather and light rain started to fall, making insects hard to find.

Despite the rain we did see four species of butterflies, an optimistic migrant red admiral at the Centre Pond, common blue and meadow brown hiding in the meadow and a hundred or more peacock caterpillars in front of the Ivy North hide.

In the morning it had been a little less wet and I had found a few more insects and other invertebrates out and about, including this snipefly, with huge eyes.

There are also a lot more siders about now.

Mid-summer is also a time for flowers, perhaps a surprise to some of our visitors, but Blashford is actually quite a good site for orchids, we have several species and sometime sin quite large numbers. This despite most of the being a “Brownfield” site, we tend to think of orchids as plants of ancient downland sites, but many will colonise freely if they get the chance. The bee orchids are at their best now and some can be seen on bank on the side of the main car park.

30 Days Wild – Day 15

Up hideously early and out to do a breeding bird survey, luckily the weather was fine, although I could have done without it having rained overnight as the trees were dripping and the tall grass very wet. Still it was calm and sunny and, for mid June, a good few birds were singing. As well as the birds I saw my first meadow brown of the year, actually lots of them and also a few common spotted and southern marsh orchid and a single Mother Shipton moth.

I arrived at Blashford by ten o’clock and had a quick check of the moth trap, rather few moths but very fresh individuals of small angle shades and lime hawkmoth. However it was the trays of creatures laid out for the school pond-dipping session that caught my eye, in particular one containing a water stick insect nymph.

The sun came out briefly at lunchtime so I went out for a break from the desk and nectaring on a hemlock water-dropwort plant was a very fresh red admiral.

There are quite good numbers of migrant insects about just now, there have been modest arrivals of red admiral and painted lady butterflies and huge numbers of the tiny diamond-back moth, so many that they have made the national news and it is not often a micro-moth does that! There are also lots of the marmalade hoverfly and silver Y moths, if you have flowers out in the garden you will almost certainly be able to see them nectaring at dusk.

My afternoon was spent in a meeting, but as it was still sunny when I got home I took a look in the garden and found this swollen-thighed beetle (Oedemera nobilis) feeding on an ox-eye daisy in our mini-meadow.

A summer wildlife walk

A very pleasant morning leading a guided walk today, with plenty of all round interest!

Things got off to a good start this morning when I opened up Tern Hide, with a female kestrel being mobbed by a couple of jackdaws. She has been around all of this week, mostly over the old ConBloc site and car park area, but for some reason she had really put the jackdaws noses (beaks!) out of joint today. While we were watching she gave up and settled on a post, with the two jackdaws standing guard either side of her, both swift to take off and harass her again if ever she tried to take off. Eventually they got bored and she settled to preening her somewhat ruffled feathers.

The light trap was very productive last night with 23 species recorded in total, including some of the more popular regulars including a poplar hawk moth, elephant hawk moth,  couple of buff tips and the high light, a Scarce Merveille du Jour:

Also pictured is this very aptly named figure of 80 moth:

Having looked through the light trap we walked on via the Ivy North/Woodland/Ivy South Hide/Dockens Water loop where highlights included a plethora of peacock butterfly caterpillars on the stinging nettles outside Ivy North Hide, meadow brown, common blue butterflies and a female scarce chaser dragonfly in the sweep netting meadow, female emperor dragonfly outside Woodland Hide, the regular grass snake in front of Ivy South Hide, along with a painted lady butterfly and newly hatched coot chick on the nest with mum, and a  male emperor dragonfly hawking along the edge of the water skiers car park.

Lots of peacock caterpillars!

Just after turning the cover towards the bridge back over the river a couple more jackdaws caught my eye. They were perched either side of a large rot hole, flying up and around it and at first I thought they were maybe coaxing outside fledglings until I realised that there were bee’s flying in and out. In fact the jackdaws were snatching these apparently tasty morsels out of the air as they entered and exited their nest in the tree. Smart birds jackdaws!

We finished off with green woodpecker and a lovely male bullfinch on the lichen heath before finishing at the centre pond for a brief glimpse of another emperor dragonfly and several egg laying azure damselflies to compliment the common blue damselflies that had of course accompanied us throughout our walk.

Shortly after one of our regular visitors and accomplished photographers spotted what might have been a young raft spider on the pond – a closer look later revealed an additional two. They are still very young and are lacking the striking yellow stripes along the abdomen, but with their greenish legs I’m reasonably confident that they are raft spiders so should provide plenty of interest over the summer if the last raft spider residents of that pond, three or four years ago, are anything to go by!
