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.

Meanwhile, Back at Blashford

Whilst Tracy was off roaming the southern side of the Forest with the Young Naturalists, I was back at Blashford where Sunday was very pleasantly sunny and warm. As the week ahead looks grey and damp, it was likely to be the best day of the week for butterflies and a good opportunity to get the transects done. Although numbers of butterflies are declining as the spring species decline there are a few summer ones starting to appear, the last couple of days have seen the first common blue and brown argus on the wing. Thanks to Blashford’s brilliant volunteers for organising and doing the butterfly transects.

The first brown argus of the year (well my first at least).

I also finally saw my first grass snake of the year too, perhaps not strictly my first as I did find a freshly dead one a couple of weeks ago, probably killed by a buzzard. This live one was rather unexpectedly crossing the open gravel behind the Education Centre.

Although it has been sunny recently it was still quite cool in the persistent north or north-east wind, this changed on Saturday and the extra warmth seemed to prompt large numbers of damselflies top emerge, I must have seen many hundreds on Sunday, mostly common blue damselflies, but including large red, azure and beautiful demoiselle.

It is very pleasing to see that two of our projects are showing signs of success again. The tern rafts are used every year, but it gets harder each year to stop them all being claimed by gulls, timing in putting them out is the key. By Monday there were at least 20 common tern on the rafts so hopefully this will be enough to fend of the gulls. The other project, the sand martin wall, has had more mixed fortunes. After a few years of success to start with it fell out of favour with none nesting for several years, but this year they are back! Not in huge numbers but a visit to Goosander hide is well worth the effort.

A number of people have asked me recently when the “new” path from the main car park to Goosander hide will open, regular visitors will have noted that the work was completed some months ago now. Unfortunately the answer is still “I don’t know” but rest assured I will make it known when it is open. The hold up is not of our making, but to do with the process of transfer from previous occupiers via our landlord and the meeting of various planning and other requirements.

The change to more south-westerly winds has reduced migrant activity, but the reserve has still seen a some waders passing through in the last few days, on Sunday a sanderling with a peg-leg was by Tern hide and today a turnstone was on Long Spit (as I have decided to christen the new island we created to the east of Tern hide this spring). Both these are high Arctic breeders and only occasional visitors to Blashford.

The martins have landed…

Sand martins that is, yesterday in fact, although they didn’t hang around long, not being there at the start or the end of the day, or indeed, this morning! Good to know that Spring is definitely here though and further demonstrated today by the little ringed plover on the bank east of Tern Hide.

Not sure if it has been around today, but earlier in the week the water pipit was still being reported – thanks to Steve Farmer for sending in this picture to blashfordlakes@hiwwt.org.uk :

An adult drake scaup was also seen again on Ibsley Water yesterday where up to two red kites have also been seen, possibly attracted to the road kill roe deer that has also drawn in raven – indeed yesterday there was a raven there throughout the day that hardly moved at all!

At the Woodland Hide visitors are still seeing brambling and lesser redpoll, and chiffchaff arrived earlier in the week – not sure when exactly but certainly on Tuesday morning there were chiffings and chaffings from all across the site! The winter wildfowl on the other hand have all but left us, as apparently, has the tawny owl that delighted all that saw him by perching out in the open south of Ivy Lake. He, I’m sure, is still there, but probably in a more discrete, and typical location. David Cuddon rose to the challenge set in one of my previous blogs and e-mailed this picture in last week (thanks David!):

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.

 

Swallows and More

I was out early doing a breeding bird survey off-site this morning and when I arrived at Blashford it was to be told that I had just missed a red-rumped swallow. This Mediterranean nesting cousin of our familiar swallow occurs as a regular, but still rare, migrant at this time of year, some of them migrate north with a bit too much vigour and over-shoot their intended destinations. They usually turn up in flocks of swallows and martins at places like Ibsley Water, so it was something of a surprise that we had not got a reserve record before now. It was reported again about an hour later and I did see a bird that was supposed to be it, but I could not convince myself that it was and before I could get a better look it flew off. One that got away!

However there were lots of other birds, at least 850 mixed swallows and martins, I estimated about 400 sand martin, 250 swallow and 200 house martin. There were also at least 6 swift, although I was told there were many more. Scanning around I also saw a red kite, 2 raven, at least 8 little ringed plover in an aerial dash past the hide and lots of buzzard. On the ground I saw my first common sandpiper of the spring and a white wagtail.  In addition the first summer little gull was still there as were at least 6 common tern.

The main work recently seems to have been raft related. We are building a new set of tern rafts with money from a grant given by Hampshire Ornithological Society (HOS). A few days ago we launched the prototype before we get on with building the new fleet.

Although the common tern are starting to arrive they won’t be getting down to nesting for a little while yet unlike the resident birds. In the last few days I have found nests of both blackbird and song thrush. The pictures show the differences between the two, the eggs of song thrush are clear blue with black spots, clearly distinct from the more muted colours of the blackbird eggs. You can also see the difference in the nests themselves. Blackbirds have a lining of grass whereas song thrush have a smooth render of mud that dries to a hard shell and no lining at all.

Spring is Sprung?

Well a bit maybe, at least today saw the first arrival of undoubted migrants with at least 15 sand martin over Ibsley Water this afternoon. Earlier in the week there had been a scatter of chiffchaff, more than have over-wintered, so some must have come in from somewhere.

Other signs of a slow change in the season have been a few peacock, red admiral and brimstone butterflies, although today’s cold kept them tucked up somewhere. Sunshine in mid week resulted in a good number of sightings of adder and grass snake.

Moth numbers are also picking up and this week we have seen oak beauty, yellow-horned, common Quaker, small Quaker, twin-spot Quaker, Hebrew character and clouded drab in increasing numbers.

Although many of the wildfowl have left there were still at least 431 shoveler on Ibsley Water today and the bittern continues to be seen from Ivy North hide, surely it will be leaving soon. Also on Iblsey Water the Slavonian grebe is still present as are the 2 black-necked grebe, now looking very smart in their full breeding colours.

The gull roost remains very large, although the big gulls have almost all departed they have been replaced by thousands of smaller gulls, mostly black-headed gull, but including 20 or more Mediterranean gull, tonight there were at least five second winter birds, 1 first winter and 15 or so adults. Unusually for Blashford, this winter has seen good numbers of common gull in the roost, typically we struggle to get double figures, unless it is very cold, but tonight I counted at least 412 and along the way saw an adult ring-billed gull. This last American visitor was not the one that spent the winter with us, but one that has arrived in the last few days, in fact it seems we may have had three different birds recently (some claim perhaps four!). During the afternoon there were also 3 adult little gull, these would be migrants, the smallest of the gulls we get and probably the most elegant.

At the Woodland hide numbers of finches are declining, but there are still good numbers of siskin, a few lesser redpoll and 10 or so brambling, including  a number of very smart males. There are also several reed bunting feeding there regularly and today, and this was a first for me, a drake mallard, not a species that immediately springs to mind as feeding outside the Woodland hide.

Spring may not exactly have sprung but it is slowly unfurling, at last.
