30 Days Wild – Day 17 – Knights In…

Moth of the day at Blashford was (and yes, you have probably already guessed it) a white satin.

This is not a rare species, although not common and one I don’t see very often at all. On the face of it Blashford should be a good site as the larvae eat willow, poplar and aspen, all of which we have in some quantity.

Other moths today that I had not recorded so far this year were the delicate.

This is typically a migrant species, although it may be able to over-winter in some years. The other”new one” was a clouded brindle, a species that is pretty well camouflaged on the mossy bark, unlike the white satin.

After a morning cutting paths and bramble regrowth I had a look around near the Centre at lunchtime and found a batch of small cinnabar caterpillars tucking into the flower heads of a ragwort plant.

Nearby I found a wasp beetle, this is one of the longhorn beetles with larvae that tunnel into wood.

It has similar black and yellow warning colouration to the cinnabar caterpillars, although I am not sure if it is actually poisonous like the caterpillars or just exploiting the fact that many birds will avoid any black and yellow insect as potentially unwise prey.

Although the reserve was pretty quiet today there are a few things to report. I saw my first fledged little ringed plover of the year, two juveniles on the Long Spit on Ibsley Water. There were also a number of flying black-headed gull juveniles too. Near Goosander hide a family of five small coot chicks were just below the sand martin wall. As the drizzle set in during the afternoon the numbers of swift and martin grew until there were at least 250 swift and several hundred martins. There was a report of 3 black-tailed godwit and I saw a redshank.  However the really big news, might actually be from last Friday, written in the Tern hide logbook was a report of a pratincole, with “collared?” written after it. Collared is the most likely, although even that is a very rare bird. Unfortunately the observer did not leave a name or any further details other than that it was on the Long Spit and flew away, not sure when it was seen, by whom or which way it went. If anyone can shed any light on this potentially very interesting record I would be delighted to know.

I returned home in persistent drizzle and took a quick look in the moth trap which I had not managed to do this morning. Three species of hawk-moth, elephant, pine and privet, matched the range,if not species, at Blashford but otherwise there was not much.

Which leaves….

What’s in My Meadow Today?

The yellow-rattle which I featured in flower at the start of the 30 Days, is now going to seed, as the stems dry the seeds will start to rattle in the swollen calyx when shaken.

30 Days Wild – Day 7 – Go-to-Bed Waking Up

Today I will start with…………..

What’s in My Meadow Today?

Mainly because I started the day with a quick look around the meadow, where I found a plant that I had not previously seen flowering in the garden. It was Tragopogon pratensis commonly known as meadow goat’s beard, meadow salsify or Jack-go-to-bed-at-noon. The last name hints at why I had not previously seen it in flower, the flowers open for only a few hours each morning and are closed by midday, so I have usually left before they open and return too late.

Jack-go-to-bed-at-noon 2

Jack-go-to-bed-at-noon in flower and closed seed heads

It is a biennial so any seed that sets this year will not flower until 2020. Hopefully I will get some pictures of the seed heads later.

Quiet a lot of flowers close up for parts of the day, many bee pollinated species close at night and moth pollinated ones open then. Ragwort is one flower that closes at night and some small insects exploit this and let the flower close around them for protection. Ragwort is a much maligned plant, it is poisonous to livestock if they eat it, as are a good few other plants. Livestock generally avoid it as it tastes unpleasant, although if it is included in hay they will eat it and it remains toxic. It is a very valuable nectar source for a host of insects and as we know flowery places are fewer than they were. Buglife produced a very good information sheet on ragwort called Ragwort: noxious weed or precious wildflower?

Generally we do control where it is close to neighbouring land and especially if these are fields where horses are kept or that are cut for hay. It can be very dominant on some recently disturbed sites as the seed can persist for long periods coming up when bare ground is created. Generally closed sward grasslands have relatively little ragwort as there are no bare patches for the seed to germinate in.

One species that is dependant upon ragwort is the cinnabar moth, both the black and yellow caterpillars and the brightly coloured moth, which often flies by day, will be familiar to most  people.

Both the caterpillar and moth can afford to be brightly coloured as they are also poisonous, they sequester the alkaloid poisons from the plant when they eat it and incorporate them into their bodies.

The moth traps both at home and at Blashford were unremarkable in their catches, but as I was locking up the Education shutters I noticed a Brussels lace moth on the wall, rather an attractive specie sin an understated way.

Locking up the Tern hide it was pleasing to see that both oystercatcher chicks are now flying well and accompanying their parents on feeding trips hunting for worms. There was also a rather unseasonal black-tailed godwit, it was not in breeding plumage so was presumably a first year bird, as they do not return to the breeding grounds in Iceland in their first summer.

 

A Great Day

I arrived at the reserve in heavy rain, always promising at this time of year and looking out form Tern hide I saw 4 bar-tailed godwit, migrants headed north grounded by the weather. Otherwise things were pretty much as the day previous day, including two very smart black-necked grebe, always a massive treat in breeding plumage.

The night had been cold (again), but there were a few moths in the trap including two new for the year, an iron prominent.

The moth trap does not only catch moths and looking through pictures from a few days ago I noticed a small fly I had not yet identified. It turned out to be a Tephritid fly, more often called picture-winged flies. Most of these have larvae that eat plants, especially seedheads of composites such as thistles. I identified this one as Euphranta toxoneura as species that is a brood parasite or predator on sawflies of the genus Pontania which make leaf galls on willows. It appears to be quite a scarce species and certainly one I had not seen before and a new species for the reserve.

Around lunchtime,as the weather cleared, an osprey flew over, it headed off east and was maybe the one seen at Lower Test nature reserve later. Unfortunately I missed it, I think at least the third one to have flown over me so far this year without my seeing any of them. The only other birds of note today were 14 black-tailed godwit and a whimbrel, briefly with the bar-tailed godwit in flight over Ibsley Water, a common sandpiper and a screaming group of about 40 swift.

Skies Alive!

Today may have been the last day of April, but it felt more like the last day of January! a bitter north-east wind was blowing hard across Ibsley Water making it foolish to open the windows at the Tern hide. The cold had brought thousands of aerial feeders low in over the water in a desperate search for any sort of flying insects to eat. At first I though they were mostly swallow and sand martin, but it turned out things were a little more complicated.

Close to Tern hide there were  a lot of swallow, whilst further out over the water sand martin were the majority. Further away house martin dominated, especially close to the northern shore of the lake. All this made estimating numbers a bit tricky. In the end I “guestimated” around 4000 hirundines were present with slightly more than half being sand martin, perhaps 2000-2500, then house martin with around 1000 and then 500-700 swallow. All in all it was quite a sight, although one that featured birds that were not at all happy. Luckily the promised rain never arrived and it actually got a little brighter later on and many of the birds left to feed elsewhere. Perhaps oddly by the end of the day swift were  one of the more numerous species, maybe 500 were feeding over the water, many more than in the morning.

Other sightings today included a yellow wagtail and a white wagtail close to Tern hide, from where I also saw a single black-tailed godwit, 2 common sandpiper and 3 goosander. Elsewhere 2 drake pochard were notable as was a single whitethroat, an oddly scarce bird at Blashford and mainly seen in autumn.

The moth trap contained just 2 common Quaker, moths don’t like cold, windy nights, but then who does.

Getting about

Sadly the title does not refer to me as I have been laid up for several days. Having done no more than look out of the window for three days, yesterday I ventured out to at least look from the car window at the fine sunny day.

I headed for the coast, feeling then need for a wide horizon. This also gave me the chance to see a little wildlife. I also came across a story of many years of wandering, that highlights the importance of the Solent coast. The carrier of this tale was a black-tailed godwit feeding beside the road at Milford-on-Sea.

Black-tailed godwit are medium sized (a bit smaller than an oystercatcher), long-legged, long-billed waders that breed on Iceland and return to the UK to moult in late summer and then to winter, staying on until they moult back into their red breeding plumage and return to Iceland, usually in late April. They feed on intertidal mudflats, pools and fields and will move between the coastal flats and flooded river valleys, avoiding the sandy shore favoured by their relative the bar-tailed godwit.

We actually know quite a lot about the lives of black-tailed godwits and they have been the subject of intense study for almost twenty years. They are attractive birds, quiet approachable and have long legs (that is important!). They are also the traditional bringer of spring in Iceland where they do not get the more familiar harbingers of most of the rest of Europe, the cuckoo and swallow.

Now for the legs! It is always important to have legs but if you are studying birds long legs allow the use of easily seen rings, which means you can individually mark birds and identify them in the field, with no need to catch them again. It was in this way that I came across a story of wanderings, thanks to RR-YX.

I could see that this bird was an adult and the worn rings told of a few years, small size also hinted at it being a male. In these days of the internet it can be very quick to get information about colour-ringed birds and so it proved for this one. It turned out that it was ringed as an adult male on 18th April 2003 as a newly arrived migrant at Vogalækur, Mýrar, Mýrasýsla, Western Iceland. This was done as part of a long-running project to track the movements of Iceland’s waders co-ordinated by the University of Iceland. But this was just the start of the tale after a couple more sightings nearby in the next couple of days he then turned up at Keyhaven, Hampshire on 17th November 2003 and remained in the area until April 2004. What was pretty certain was that he would have left Iceland well before November, so was he in the Solent unseen?

The following autumn gave a clue to where he might have been, in August 2004 he was seen at  Killingholme, on the Humber in Lincolnshire before turning up again at Keyhaven in November and then staying until at least 13th April 2005, although there was a surprise, a brief trip to the Ouse Washes, Cambridgeshire in mid February. It was again at Killingholme in the autumn from July, staying at least a couple of months before again being seen at Keyhaven in November staying until late March. The autumn of 2006 saw him avoid the Humber as far as we know and appear in Keyhaven in October, after a trip to Newtown on the Isle of Wight in November he was not seen all winter until appearing at Titchfield Haven at the start of March 2007 and then on the River Avon at Ibsley on St Patrick’s Day.

The next few years saw the general pattern of autumn on the Humber, winter at Keyhaven continuing. Sightings became more interesting in 2013, with a trip to Coward’s Marsh, Christchurch Harbour in February, then the Ouse Washes on 1st April, Benbecula in the Western Isles on 23rd and then SW Iceland on the 25th. Not quite as good as a satellite tag, but you can still see get the picture and a lot cheaper and now ten years after he was ringed! Further sightings followed at favoured sites with another in Iceland in May 2015.

When I saw him yesterday he was over sixteen years old and back at an old haunt. Many people see colour-ringed birds and do not report them as “They will have been seen before” or someone else will report it. What his story shows is that all the records together produce a story of regular haunts on which he mostly relies of survival, but also of a knowledge of other key sites all around the country. His tale shows how our wildlife relies on a network of sites, regular returning shows how continuity of habitat is important, he knows where he is going and what to expect when he gets there. So we need to look after networks of sites across the whole of these islands and further still and we need to ensure that they persist, a new site will not automatically get added to the inventory as an immediate substitute for the loss of a traditional location.

Lastly his trip from Benbecula to Iceland in 2013 shows his speed of travel, in fact it will have taken him well under the two days to make the flight as he took the spring to Iceland with him after we looked after him for the winter.

Please do report any colour-ringed birds you see, there might not always be a long story but there just might be. You can report them via the BTO at  BTO Ringing Scheme and click on the “report a ringed bird” icon on the top left side (you can report all ringed birds you see or find here, not just colour-ringed ones). For some schemes you can track down the ringer which can get you the details much faster, but there are links as to how to do this there too. Not only is it fascinating but it provides invaluable data for nature conservation and gives insights as to how we might go about serving the needs of real birds.

For colour-ringed birds note which leg the colours are on, where they are in relation to the leg joint “knee” and where the metal ring was if it can be seen. By convention the combinations are quoted with the bird’s left leg first then the right, so this one was RR-YX.

Just imagine looking at him from behind and you will get it right! Oh, and get a picture too if you can.

 

 

 

 

 

A Full House

The poor weather over the last couple of days has brought in huge numbers of hirundines, that is swallows and martins, to Ibsley Water. there are especially very large numbers of house martin, they are impossible to count but I estimated at least 5000 today with probably 1000 swallow and at least 500 sand martin. Everywhere you looked over the water there were birds and then, scanning upward against the clouds there were many, many hundreds more. These higher birds are mostly house martin the swallow and sand martin tend to keep lower. They gather over water in an effort to find insects in weather when there are few flying elsewhere, often they pick prey directly from the surface of the lake.

The other aerial plankton feeder of summer is the swift, they mostly leave around the end of July, but a few can linger and searching through the hirundines can sometimes result in finding one and today was just such a time. Swift in September is a scarce bird, in fact in some years I don’t see one after mid August.

Other birds today included a hobby, lured in by the masses of martins as potential prey, although I did not see it catch one. The great white egret was around on and off, the ruff of the last few days was joined by another by the end of the day, when there were also 2 juvenile Arctic tern. A single black-tailed godwit dropped in for a while and there were 2 sanderling reported.

This is really not the weather for moths, so tomorrow’s planned “Moth Event” promises to be a bit of a damp squib. Today’s catch total a massive two moths! I suspect tonight may well be worse. The highlight was a fresh frosted orange, always a nice sight.

Several people mentioned the very good show of flower put on by our small patches of heather near Ivy North hide this year, in fact there at small patches of heather in several places across the lichen heath and I suspect these will expand in the coming years. All of this heather is the common ling, but we do have one plant of bell heather Erica cinerea on the reserve and this is in full flower now, somewhat after the ling has finished.

Although it is feeling very like autumn already there are still some reminders of summer out there, such as grasshoppers, I found this somewhat atypically coloured field grasshopper near the bell heather at the end of last week.

30 Days Wild – Day 28: Good for Snails?

This maybe the time of year when the sun is at its highest but it was hard to tell today as it never actually stopped raining, it eased to drizzle at times, but never stopped.  It seemed that the return of wet weather had every froglet, toadlet, slug and snail out and about in celebration of the end of the hot, dry days.

The night was damp but warm with the cloud overhead and the moth trap was quite busy again, I had only one out last night. Although it is a “Moth trap” it would be more correct to call it a nocturnal flying insect trap as it catches many other insects, in fact sometimes many more non-moths than moths. One of last night’s non-moths was a fly and one that probably also benefits from damp conditions as it was a snail-killing fly. It is actually the larvae that are the killers of snails and slugs. Considering I have so many slugs and snails in my garden it is surprising I have never found a snail-killing fly there, although the reason for this is that they do not generally prey on the common garden species.

I also realised that yesterday’s moth catch included one that was new to the reserve, although all the books describe it as “common”, I had never seen one before. It was a green arches. Looking at the distribution map for Hampshire it is apparent that it avoids the New Forest area for some reason, despite being a moth of damp woodland, perhaps it does not like acid soils.

The heavy rain in the morning did present one surprise, as I opened up the Tern hide there was a flock of 20 black-tailed godwit flying around, eventually landing to the east of the hide. They were all in fine, red breeding plumage, these were Icelandic godwits returning to the south coast for the winter, or at least to moult. They had all their wing feathers too, which would indicate that they had probably arrived straight from Iceland and just been forced low by the rain. This early in the “autumn” they will be birds that have failed to breed successfully so head to the south coast of England to undergo their post-breeding moult. This will start only once they get here so they can make the journey fully feathered, having arrived they will start to moult their wing feathers almost immediately. Moulting is an energy intensive business, but there is lots of food in the mud at this time of year and not many waders around competing for it, so their strategy is a good one. A lot of godwits from this population have been given colour-rings, so when they landed I checked through the flock, but there were all unadorned.

So Close and Yet so Far

A rather better day today, sunshine in place of steady rain. My first sight upon looking across Ibsley Water was of a merlin sitting on the osprey perch out in the lake, not a bird I see at Blashford very often. I was also at the reserve to lock up yesterday when the bird of prey of the day was a marsh harrier feeding on something on the western shore of Ibsley Water. Also on Ibsley Water today were a black-tailed godwit, a curlew and 4 pintail. yesterday evening at dusk I counted 45 pochard and 22 goosander, so the waterfowl roosts are slowly increasing in numbers. In the same vein, tonight there were a few thousand starling gathering to the north of the reserve and the first indication of a greenfinch roost near the main car park, with perhaps thirty birds gathering.

With the day set fair I took the chance to clear some of the paths of leaves and do so cutting back. Despite the recent frosts there are still quite a few fungi about.

Candlesnuff is one fungus that can be seen all year round, but I rather liked this group with water droplets on them, they were beside the path between Ivy North and the Woodland hide.

Along the Dockens Water path I saw a firecrest in the holly and for a change it was not hidden in the shadows but out in the sun, looking very jewel-like. This path is looking really good at the moment with the trees in full colour.

Clearing leaves from the path towards Rockford Lake I found a raptor plucking post with the remains of a jay, it could have been taken by a female sparrowhawk although, these days, a goshawk might be just as likely.

I had seen “Walter” the great white egret at Ivy North hide when I opened up and heard water rail and Cetti’s warbler there too, but the bird of the day from there was the ferruginous duck, which spent the afternoon in front of the hide. Unfortunately I missed it as by the time I heard about it it was more or less dark. This is no doubt the drake that has been returning to Blashford for some years, although it usually frequents one of the private lakes to the south of the reserve.

In the late afternoon I was at the Goosander hide hoping to see some colour-ringed gulls on the perching rails there. There were gulls, but none with rings.

Lesser black-backed gull, yellow -legged gull, herring gull and black-headed gulls.

Yellow-legged gull are slightly large and darker than herring gull and typically have whiter heads in winter, lacking the grey streaking of herring gull. The picture above shows a fairly dark lesser black-backed gull, with the yellow-legged gull in the centre and a typical herring gull on the right.

As I went to lock up the Moon was just rising, close to the horizon it always look large and this evening it looked especially so. It has good reason though as apparently it is closer to us at present than it has been for 68 years, so I really never have seen the Moon look so big.

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.

Hybomitra distinguenda 2

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.

 

Signs of Spring?

Aside

Apologies for lack of posting,  but I’ve been having a few problems with getting onto the internet over the last couple of days so here’s just a quick blog of some highlights from Sunday and Monday.

A scheduled guided walk on Sunday was entitled ‘Spring Firsts’ and although the conditions weren’t very spring-like we did manage to see a few token indicators of spring. The native daffodils were well in flower as were a few greater celandine. The 100+  sand martins over Ibsley water and a fine male scaup seen from Gosander Hide confirmed that birds are on the move.

Later that day we were lucky enough to catch up with a couple of little gulls (an adult and a juvenile) hunting over Ibsley Water. I believe they’ve were seen on  Saturday, but weren’t in evidence today (Monday). I know gulls aren’t everyone’s idea of exciting birds, but it’s always good to see something a little different. I managed a few distant images which show some of the field marks and behaviour to look out for.

Several hundred black-tailed godwit have  also been making use of Ibsley water, many roosting on the peninsula to the right of the Tern Hide. Some ten of these are carrying colour rings on their legs and Pete Potts , co-ordinator of “Operation Godwit” and who has been ringing these birds both at Farlington and in Iceland, was trying to check out these rings. He reported that several had been ringed locally and some in Iceland and at least one of them was first ringed 18 years ago, when it was already an adult.

Pete would be very grateful if any colour ring records of black-tailed godwits that visitors might make could be e-mailed to him at pmpotts@tiscali.co.uk.

One of the features of this time of year has been the influx of more woodland birds onto the reserve, and into many gardens, as the depletion of natural food and the fact that many birds are starting to move back to their breeding grounds, has led them to make greater use of the food we put out.  Whilst lesser redpoll and siskin numbers on the reserve are still high, the number of brambling have increased significantly with up to twenty taking spilt niger seed from around one of the feeders outside the Woodland Hide.
