30 Days Wild – Day 21: More Dragons than Game of Thrones

Although thankfully less death and destruction and all the dragons are dragonflies, they are really enjoying the hot weather. From a photography point of view the heat makes it very difficult to get close to them as they are extremely active. I saw lots of emperor dragonfly today, there have been a number of reports of  the migrant lesser emperor in recent days, although none from Blashford as yet. I did manage to get a picture of a male black-tailed skimmer today though, perched along the path to Ivy South hide as I went to lock up.

The butterflies are also liking the conditions although avoiding the very hottest part of the day. I did see my first ringlet of the year, again on the path to Ivy South hide, they are usually most frequent on the northern side of the reserve, it was too active for me to get a picture this time.

In recent days I have noticed that there almost always seem to be stock dove on the lichen heath, yesterday there were at least eight there. They seem to be picking at the vegetation, or possibly seeds, often they don’t immediately notice me on the path allowing some good views until they suddenly realise I am there and race off with a clatter of wings. Otherwise it was generally quiet, from Tern hide it was good to see two little ringed plover chicks as I opened up along with the single oystercatcher chick.

30 Days Wild – Day 15: Trying to Impress

I was out on the eastern side of Ibsley Water with the volunteers this morning to clear the areas we cut and which are grazed by ponies of ragwort. It is toxic to animals, but they will usually not eat when it is growing, however they will if it is cut and gets mixed with grass or hay. At one time it was one of the commonest plants in this area but now it is much reduced and overall the grassland is looking much better, with quite a good range of species. A couple of highlights this morning were several patches of corky-fruited water-dropwort.

Corky-fruited water-dropwort is an Umbellifer, one of the carrot family and is very attractive to insects, this one had lots of pollen beetles on it. It is quiet frequent in unimproved grasslands in a swathe roughly south of the M4, so it is pleasing to see it at Blashford where the grassland is still recovering from the ravages of mineral extraction. Another find was knotted clover, a plant of dry sandy places, often near the coast, I am not sure if I have found it at Blashford previously.

At lunchtime I tried the pheromone lures for clearwing moths again, completely without success. However I did spot a handsome black-and-yellow longhorn beetle.

After doing various odd jobs in the afternoon I went to lock up the hides and found a pair of crab spiders on a hemlock water-dropwort flower head, The male is quite different from the female and a lot smaller so he has to tread carefully if he is not going to get eaten.

It seemed it was not only the spiders that were making plans, on a nearby ox-eye daisy I saw a female hoverfly Eristalis horticola, with a male hovering low over her and darting from side to side. I am not sure if she was impressed but he was trying hard to dazzle her with his advanced hovering skills.

I also found another slime mould, on the same log as the one the other day, although this was clearly a different species.

The only new bird sighting of note today was of a first summer little gull as I locked Tern hide. It was pleasing to see that the single oystercatcher chick from gull island has fledged and that the remaining one near Tern hide is close to doing so. In additions the single large lapwing chick is also close to flying and two of the smaller ones are still going strong. Even better was a sighting of two well grown little ringed plover chicks today. On Ivy Lake the common tern chicks are growing well and most broods seem to still be of three chicks.

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.

30 Days Wild – Day 6: And the Wind did Blow

And how it blew! And how it rained too, very unseasonal gales to tear at the trees and soak fluffy wader chicks. So it was with some trepidation that I got to Blashford today. Looking from Tern hide when I opened up I saw at least two of the small lapwing chicks and spotted one of the oystercatcher offspring too, although they should be well able to survive a bit of weather by now. A few of our trees had not done so well, no major fallers but several branches down, at this time of year, in full leaf and soaked with rain, the wind can really get hold of a branch twisting and breaking it off. Luckily the volunteers were in and between us we were able to walk the full length of all the paths clearing branches as we went and then returning to saw off the few larger leaning stems.

At lunchtime a smooth newt was spotted on the surface of the Centre pond, Jim then realised that it had been caught by a great diving beetle larva, these are ferocious predators but I was surprised that one would tackle a full grown newt.

The newt was struggling but it was hard to see how it was going to get the beetle larva off as it had its jaws firmly embedded. As we watched a second, equally large larva closed in and joined the attack, I don’t think the newt had any chance against two attackers. I knew they would tackle prey larger than themselves but this was the first time I had seen one take on something so large. The picture is an example of “Digi-binning” that is holding the digital point and shoot camera up to one eyepiece of the binoculars.

Unsurprisingly the moth trap was very quiet, I doubt many moths tried to fly and those that did probably had trouble getting anywhere they wanted to go. Amongst the few that did get out and into the trap was a very fresh mottled beauty.

The weather did improve a bit in the afternoon and there were quite a few insects flying as I went to lock up, lots of damselflies and various things nectaring on the flower heads of hemlock water-dropwort, one of the best food sources for lots of species at this time of year. I cannot identify them but the many insects include a number of sawflies.

Looking after a nature reserve can be rewarding, especially when you can work to improve habitats, allowing them to support more species and individuals, in the jargon increasing biodiversity and biomass. On a reserve such as Blashford Lakes there is the additional goal of increasing the accessibility of this wildlife to allow appreciation and enjoyment for people. Increasingly it is being realised that this is good for our health, diverse green space really matters to our wellbeing, individually and as a society. It is also a small push back against a tide of mass declines in species abundance and variety, to make a real difference to that needs action on a much larger scale than just a nature reserve.

So on Day 6 of  my 30Days Wild I have to confess to getting a little wild myself. I have already blogged about my tiny back garden meadow and we are doing work at Blashford to enhance the grassland to support more species. Species rich grasslands and meadows have been one of the fastest declining habitats in recent decades, with the accompanying loss of wild flowers, butterflies and the rest of the species such places support. Local Authorities and Government Agencies have a duty to enhance the environment where possible. There has recently been much publicity about the importance of grass verges for wildflowers, it has made national radio and some species are now almost only found by roadsides.  The Highways Agency publishes very good guidelines for the management of verges, round-abouts and other roadside grass areas, with the idea that managers of such places will have a best practice guide to follow.

So what made me wild? It was the close mowing, for the second time this season, of the large (probably 0.5ha or so) round-about at the end of the road where I live. This does not improve safety, to do this at most a couple of metres around the edge would need mowing, nor was it tall, no more than 30-40cm and the mass of corky-fruited water-dropwort was just coming into flower. The first cut dealt with the cowslips and much else besides, this is a relatively herb-rich grassland that is being systematically destroyed by close mowing and swamped by a layer of mulched cuttings each time. Eventually this will ensure it has only a tall coarse sward of cocks-foot, thistle and nettle and another vestige of our grassland heritage will have gone. I don’t know which particular arm of authority undertakes this mowing, but the guidelines have evidently not reached them! So long as there is careless disregard for such places the march to environmental mediocrity will continue and we may as well lay Astroturf and be done with it!

Normal service will be resumed tomorrow, unless the “Wild” part of 30 Days Wild takes hold again!

30 Days Wild – Day 5: Wet and Windy

Not a very June-like day, with increasingly strong winds and rain getting heavy by the end of the day. Not the kind of conditions to be a newly hatched, fluffy lapwing chick and not the conditions to be an adult lapwing trying to keep your chicks alive. In front of Tern hide the brood of tiny chicks I first saw yesterday turned out to be a family of three. The adults have a difficult line to tread, if they brood the chicks, keeping them warm and dry, they don’t get enough food and ultimately starve, if they let them feed they run the risk of getting wet and cold and dying anyway. So prolonged wet windy weather is very bad for chick survival, let’s hope there are enough dry breaks in the weather to give them have a chance.

Lapwing and oystercatcher chicks

As it the weather was not enough the adult lapwing are very protective of their chicks and see danger everywhere, in this case they seemed to think that the oystercatcher and her chick and the starlings were unacceptably close and needed driving off.

The oystercatcher chicks are somewhat larger now and able to cope with a bit of adverse weather. When they get to this size the adults often take charge of one chick each, watching over them and feeding them, with the chick finding a little food itself.

The poor weather brought lots of swallows, martins and swifts to feed over Ibsley Water, the numbers growing throughout the day as the conditions worsened until, by the time I closed up I estimate there were at least 1000 swifts, an amazing sight. I got a picture, but in the rain it is hard to make out the birds, I think there are probably about 75 in this shot and the whole sky was filled with them.

30 Days Wild – Day 1: Weird Stuff

Here we are again, another June and another 30 Days Wild, I will try to keep up this year and post something every day.

I was at Blashford today with the volunteers tidying up on the southern shore of Ivy Lake, clearing away some old tern rafts and doing a little Himalayan balsam pulling, actually the volunteers did these things, I cut a few brambles and set up the telescope to count the nesting common tern. I am pretty sure we now have 25 pairs on the rafts with nests and eggs, possibly 26 pairs. So with five pairs on the Pound we have reached thirty pairs for the first time! This has been a really successful project and almost entirely the work of our great volunteer team. Over the last ten years the Blashford terns have consistently produced more flying chicks per pair than any other local colony, with many pairs achieving the magical 100% success rate, laying three eggs and fledging three chicks. Over the last year we have made a whole set of new rafts funded by a grant from Hampshire Ornithological Society (HOS) to a design refined and honed by our volunteer team.

During the course of the work we came across two grass snake, a nest of bank vole and a number of dragonflies including an emperor, scarce chaser and broad-bodies chaser.

The weirdest thing I saw today though was an old favourite of mine, a slime mould, these are strange organisms that usually live as single cells but aggregate to form sporangia and it is this stage that we can see on old wet logs. The one I found today near the Woodland hide was a Stemonitis, possibly Stemonitis axifera. They take less than a day to aggregate, develop and produce spores and then disappear.

Regulars will be pleased to hear that the two lapwing chicks and the two oystercatcher chicks are still doing well outside Tern hide, with an additional and larger, oystercatcher chick in the distance on Gull Island as well.

You can see various 30 Days Wild stuff on Twitter via #30DaysWild and probably lots of other places too and it is still not too late to join the over 45,000 people who have signed up to do something wild on 30 Days. Our environment is vital to our wellbeing, physical and mental health and it is where we live, despite this it is not getting much attention

Stay Close

At the Tern hide there is still a pair of lapwing with three chicks and now also a pair of oystercatcher with two chicks. Lapwing are good parents, they will defend their chicks vigorously, but they still have to find their own food and so wander off making them vulnerable to predators. Oystercatcher are great defenders and also find food for their chicks. This has two clear advantages, the chicks can stay very close to their parents and they get  a lot more food. I watched the birds yesterday afternoon and the adults were feeding the chick a good sized food item every 30 seconds or so.

Oystercatcher chicks stay close for protection and food.

A number of people told me there was only one chick, but this mistake is easy to make as the adults seem to concentrate on feeding one chick at a time the other resting, well hidden and probably digesting all the food it has just had.

More dragonflies are noticeable around the reserve, yesterday I saw broad-bodied chaser and black-tailed skimmer and numbers of damselflies are really impressive.
