Whilst I was Away

A real frost this morning, the cold going well with the arrival of goldeneye and goosander on Ibsley Water. There were four goldeneye reported yesterday but today there were at least seven, including two adult drakes. The goosander required patience, as it was not until dusk that I got the full count, 20 were present around lunchtime, but at the end of the day I counted 51 gathered to roost.

Having not been on the reserve for a week, I was catching up on sightings whilst I was away. Without doubt the top spot goes to a report of a shore lark seen right in front of Tern hide at around 11:00 on 23rd October, a really good bird anywhere in Hampshire and probably the first ever inland record for the county. Other notable records have been of two marsh harrier seen on several days, including today, a little gull and a cattle egret seen yesterday, a water pipit reported a couple of times and the bittern, on one occasion seen on the Ivy Silt Pond at the same time as an otter. Great white egret are still being seen all around the lakes and there are clearly at least three around, including “Walter”.

A Perfect Day

It was a glorious day at Blashford today, to my mind the perfect balance of sunshine and cool temperatures, the ideal autumn day for getting work done on the reserve. It was also a pretty good day for birds, although many of them have been with us for a while now.

When I first looked from Tern hide as I opened up I saw the two young little gull and thousands of house martin, low over the water, I estimated 3000 at least but they were everywhere low over the trees, lakes with others high in the sky. I could see no sign of the black tern or grey phalarope. A small wader on the gravel island way out near the middle of the lake caught my eye, there was something of a redshank about it but it was not one. This meant wood sandpiper was the most likely candidate and after a little while it was disturbed by a black-headed gull and made a short flight confirming the identification, our second of the autumn.

Later in the day it turned out the phalarope was still present and I got good views of it as I locked up. Other birds included both great white egret, at least one green sandpiper and reports of common sandpiper, I missed that, so did not get the “Sandpiper set”. Locking up the Ivy North hide I saw a pintail, the first for a few days.

I got no pictures of birds, or anything else today (working too hard, obviously!). However I will post a few pictures of recent notable records from the reserve, not great pictures mind you. The first is of a small Tortrix moth Olinida schumacherana, which seems to be the first record for the 10km square that includes the reserve.

The next is the Australian Pyralid moth that we first recorded last year as possibly new for Hampshire. In appears to have been introduced with the tree ferns that the caterpillars eat, although it now seems to be finding local ferns to its liking.

It was first found in the UK in Dorset in 2009.

I will end with a couple of pictures from my garden, two late butterflies bringing  a little colour to the end of their season.

After a windy night I looked out over Tern hide this morning with some hope of seeing something new blown in. I was greeted by an adult peregrine perched on one of the posts outside Tern hide and unsurprisingly not many other birds.

Scanning further up the lake I spotted the juvenile black tern that has been with us for a while, then a second bird also dipping over the water, this time a young little gull, later it became clear there were two of the same age. Lastly I noticed a small wader flying low over the water, it took me a moment to realise it was a grey phalarope, no doubt blown inland overnight and if the forecast is correct probably the first of many.

There were still hundreds of hirundines, it seemed more were house martin today, but it may just have been that more martins were low over the water today. With all these martins it was perhaps inevitable that a hobby would be drawn in to hunt them and there was at least one for a good part of the day. It engaged in fantastic dives, steep climbs and stall turns that would have even have impressed the spitfire pilots that once flew from here. In mid afternoon the phalarope caught its eye and apparently it managed to knock it into the water, luckily it seemed uninjured and flew off high to the east with the hobby in pursuit. A few minutes later a hobby flew in from the east, so it was hoped that the phalarope escaped.

The volunteers were working to cut back the path to Lapwing hide today, normally this is a quiet part of the reserve, but the phalarope attracted a fair few admirers so we saw a lot more people than usual. With almost five miles of paths on the reserve keeping them open in the face of fast growing brambles and and descending willows is a constant task, especially with autumn gales added to the picture. We were not just cutting back but also trying to create sheltered bays and edges for insects and reptiles, so this was combined habitat creation and access work.

Back to some birds

I have been off for the week and today was my first day back. In my absence the reserve has turned green! Many of the trees have leaves bursting through and around the lakes emergent plants are doing what they do best and emerging.

The change of seasons is very apparent, with Ibsley Water having swallow, sand martin and a few house martin swooping over at least 47 wigeon and a goldeneye, reminders of winter. A fine adult little gull was hunting insects over the lake in the morning, but seemed to have gone in the afternoon. The rain of early afternoon brought in a flock of 25 Arctic tern, always a treat and at the end of the day some of them had joined the 4 common tern on the shingle near Tern hide giving a great comparison.

Migrants generally are still rather few apart from chiffchaff and blackcap, which are both around the reserve in good numbers. Today I found just singles of willow warbler and reed warbler, we usually have just one pair of willow warbler but there should be many more reed warbler to come.

Other more random sightings I had today included a red kite, a pair of mandarin duck, 4 goosander and 3 snipe. I also had reports of 2 white wagtail and a common sandpiper.

April Showers

Or more prolonged outbreaks of rain! Recent days have certainly been making up for the rather dry winter. The lakes which had been unusually low for the time of year have now filled up to the point where a number of the islands in Ibsley Water have disappeared.

On the plus side it has warmed up a little and this has resulted in something of an upturn in moth numbers. Last night saw nine species caught including early grey and brindled pug new for the year, there were also a number of oak beauty.

Spring migrants continue to arrive in low numbers, there are now several chiffchaff and  a few blackcap singing around the reserve and today we recorded our first terns of the year. The single common tern this afternoon was not unexpected, but the 4 Sandwich tern this morning were unusual and they were flying over heading south! The adult little gull was still around in the morning at least, it has been a near record season for them and we have probably already recorded about 20 individuals. Yesterday there were still at least 13 goldeneye and probably the same today, a hang over from winter with 50 or so sand martin and 5 or more swallow feeding over their heads.

There are now common dog violet, ground ivy, moschatel  and cowslip starting to come into flower. Ground ivy is normally very popular with the early butterflies, but recent days have been too cold and/or wet for them to have been flying.

As though the emphasise the changeability of the season I saw this intense rainbow as I went to lock up the Tern hide this afternoon, hopefully the ratio of rain to sun will start to change soon.

Staggering into Spring

Another rather wintry spring day. I drove across the Forest in heavy sleet, although the pull of spring was still evident, as I passed two displaying curlew and opening up the main car park there was a blackcap singing. Over Ibsley Water there were 3 little ringed plover displaying and about 40 sand martin with a single swallow seeking insects. There was no sign of yesterday’s 5 little gull though, but a closer look revealed a single wheatear on Long Spit.

Elsewhere at least 11 brambling at the feeders by Woodland hide were a welcome bit of colour and a number of chiffchaff were singing.

A afternoon look at Ibsley Water resulted in an Iceland gull, which flew in from the east, bathed and then joined a number of herring gull on the western shore, however a look later seemed to show it did not stay. I got a couple of typically poor shots of it!

It was a bird in its first year of life, in plumage terms not first winter as they remain in pretty much juvenile plumage during their first winter, anyway a “young” one.

Although the Iceland gull had gone by the time I was locking up there was a compensation as the ring-billed gull was there. It now looks very fine, with a completely white head and well coloured bill with a strong black ring. As I watched it gave a full long call, throwing its head back, unfortunately it was too far away to hear in the breeze.

Changeable

The last week or so has been very strange, with the arrival of several migrants and further snow.

Spring!

On the migrant front there are now small numbers of sand martin hawking over several of the lakes, the most I have seen together is only six. On Ibsley Water there have been at least 2 little ringed plover, but be warned as there has also been a ringed plover. Other waders in the snow last weekend included a few dunlin and 3 golden plover. A single swallow has been recorded on several days and is perhaps the one reported in North Gorley as well. In the woodland small numbers of chiffchaff are singing and near Tern hide a pair of wheatear have been seen for the last four days. Perhaps the greatest excitement has been the sighting of 2 osprey passing singly overhead in the last week. typically for spring birds, they did not linger.

Other notable sightings have included up to 5 stonechat beside Ibsley Water, this is usually a very scarce species on the reserve, I suspect these are birds that had returned to the open Forest before snow and moved into the valley to escape the worst of the conditions. Two adult little gull have been over Ibsley Water where numbers of Mediterranean gull are increasing and the ring-billed gull is still being seen int he evening roost.

As thought to highlight the confusion of the seasons there have been birds starting to nest and the dawn chorus has gone up a gear. The picture below was taken through my kitchen window and shows blue tits investigating a nestbox in the snow.

The drive to start breeding is not stopped by changeable weather.

 

30 Days Wild- Day 16: The Curlew’s Cry

I spent a good part of the day at a small reserve in the New Forest at Linwood where we are discussing a habitat restoration project with the Our Past, Our Present Heritage Lottery project. The reserve is small but interesting as it is in the New Forest but not grazed by livestock. It is mainly woodland of quite recent origin and within the trees are areas of mire and it is maintaining these that is the objective. The open history of the site is attested by the patches of bog myrtle and the rare white sedge. The sedge is not that rare nationally but is predominantly a northern and western species and is rare in southern England.

The New Forest is something of a haven in southern England for species that are otherwise typically more often found northern or even upland areas. The reason is mainly that it is one of the few areas with bogs and mires in this part of the country. One of the once typical birds of such places, the curlew called repeatedly from the open bog beyond the reserve as we were looking around. There are now only about 40 pairs remaining in the New Forest and breeding success is worryingly low. As with many other species habitat change is probably a major factor nationally, but within the New Forest increasing recreation is probably a factor too, since the habitat appears to remain much as before.

There was not much news from Blashford, although the second year little gull was still to be seen from Tern hide.

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.

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.
