A Constellation of Garlic

A fairly busy day on the reserve today with a steady stream of new visitors, it is always good to encounter people who are still just discovering us after all this time! I was out with the volunteers removing brambles from a warm south-facing bank which I hope will prove popular with insects and reptiles.

It seems odd to say there was not a lot of bird news when the Bonaparte’s gull was still present, but it has been here a while now and most who were keen to see it have done so by now. The first summer little gull is also still with us, otherwise migrants were a dunlin, a whimbrel and at least three common sandpiper. Numbers of swift have increased again I think, with at least 100 zooming noisily about this afternoon.

Out on the edge of the lichen heath I saw a small copper and a grey-patched mining bee.

I only saw my first damselfly of the year a couple of days ago, I don’t think I have ever waited until May before I saw my first of the year before. My first was, as expected, a large red damselfly and today I saw a single female common blue damselfly.

As you can see it is not at all blue, but it has not long hatched out and has yet to acquire its colour, many females do not get all that blue anyway.

The wild daffodil have long since ceased flowering and the bluebell are starting to go over, but the reserve’s only patch of ramsons, also known as wild garlic, is looking very fine and in full, starry flower. Half close your eyes and it looks like a firework display  worthy of any New Year. I was hoping to find the hoverfly that feeds on it as it would be new for the reserve, but no such luck.

Although I had not luck with the hoverfly I did find a snail-killing fly near the Centre Pond, I think it is Tetanocera ferruginea.

Although it was a rather cool night the moth trap did catch a few species including my first pale pinion of this year, never an abundant species, I usually see only a few each year.

Bonaparte’s Again

A couple of years ago Blashford Lakes was visited by a first year Bonaparte’s gull, a small species between little gull and black-headed gull in size and looking very like the latter. They breed in North America and very occasionally get blown across the Atlantic. Most turn up in this country in spring and are first year birds. It seems probable that they are blown across in autumn storms and are following a natural instinct to migrate north after wintering well to the south of us. Yesterday the second of this species to be found on the reserve was seen from the splendid new Tern Hide and attracted a fair few birders as the news got out.

Although similar to a black-headed gull the differences are not too hard to see up close, although this bird is somewhat larger than our last and so less obvious. At long range and especially if feeding on the water, it is much less easy to spot. However there are some clues that might help. The most obvious is the difference in feeding action, the Bonaparte’s has a habit of up-ending and overall swims with neck very stretched looking reminiscent of a phalarope, with their faster feeding action as well.

The Tern Hide is also proving a great place, appropriately enough, to see terns, specifically common tern.

The last few days have seen a few migrant birds passing through or arriving, we have recorded our first swift and migrant waders like dunlin and whimbrel. I have not managed to get pictures of any of these but I did snap a red kite that flew over on Monday.

The spring is not all about birds though, as the season moves on we are seeing lots more insects such as small copper, holly blue and many spring hoverflies.

We are also seeing more reptiles and I found the grass snake below basking beside the main car park!

Our developments are still ongoing, but are drawing to a close, however the latest job will be to resurface the car park nearest the Education Centre, meaning it will be unavailable for parking for a few days, most likely next week. We are nearly at the end of the works, so things should settle down soon! Thank you to New Forest LEADER for funding our improvements to the area in front of the Education Centre.

Progress Against an Invader

Thursday at Blashford is volunteer day and we had a good turn out of fourteen for our first Himalayan balsam pull of the year. After many years of pulling this plant we have very significantly reduced the population and it is nowhere the dominant plant. The advantage of doing the first sweep early in the season is that we remove a significant number of plants but also get an idea of where the main problem areas are and so where to concentrate on our later visit. Pleasingly we found no more than a couple of hundred plants on about half the length of the stream, enough to suggest that there is still a seed source upstream  somewhere but not so many that it is having a serious impact on native wildlife.

The common terns are finally taking some interest in the rafts on Ivy Lake, although they are still not really taking control of any in numbers sufficient to deter the black-headed gulls. I tried putting out another raft during the afternoon in the hope that a new one might tempt them in. The gulls often just loaf around on the rafts, but have the annoying habit of bringing reeds and sticks and leaving them scattered  over the surface. I suspect they are mostly young adults, as the older birds started nesting a couple of weeks ago, a few may eventually build a proper nest, but in the meantime their practice efforts are putting off the terns.

Generally things were quite across the reserve, most of the birds are now nesting or getting ready to do so. Our visitor form North America, the Bonaparte’s gull is still to be seen, although it does not now attract more than the occasional admirer. I did manage to get a slightly better picture of it, which does show a couple of the differences from black-headed gull. You can see the slightly smaller size and overall thinner, more “pointed” look. Now that it is getting a summer plumage hood you can also see that this is blacker than that of black-headed gull, which is actually chocolate brown.

A very noticeable feature of the past week has been the huge increase in the numbers of damselflies around the reserve. Common blue and azure damselflies are now out in numbers, but the large red damselfly, typically the commonest spring species is very hard to find, perhaps due to the very poor April weather last year.

 

 

Out and About in the Sunshine

It has been very, very dry recently and reasonably sunny, however it has also been quite cold for a lot of the time, with north or north-east winds. This has made for quite a good spring for insects, certainly better than for several years, although it could do with warming up a bit and we will need some rain, not too much, just enough to keep the vegetation green. Yesterday it was warmer and the wind swung round to a more southerly direction.

I finally saw my second dragonfly of the year, I have seen lots of damselflies but dragons have been in very short supply. Although the view was brief I think it was a hairy dragonfly. I also found several of one of my favourite insects, groundhoppers, small relations to grasshoppers that get easily overlooked as they are adult in spring. There are three species in Britain and we get two of them at Blashford, or at least sop far I have only found two species. They favour damp, bare ground and can both fly and swim! The one below is a slender groundhopper.

I was out bird surveying at the start of the day at Linwood reserve and noticed that the leaves on the oak there are mostly brown, almost all the first flush of leaves dead. Linwood lies in the valley of the Dockens Water a well known frost-hollow, these leaves had all been killed by the late frost that also had my early potatoes. This will be bad news for the nesting blue tit on the reserve as they mainly feed their chicks on winter moth caterpillars and these eat the first flush of oak leaves.

Hawthorn, or may, traditionally flowers in May, although often it seems to be earlier, this year it has lived up to the name and was in full bloom in the first week of the month. Although it has lots of flowers they do not seem to attract as many insects as the earlier blackthorn flowers, however one in a good sunny spot can still be worth checking for bees, hoverflies and beetles. I spotted this leaf beetle nectaring on the bush close to Ivy South hide as I locked up yesterday afternoon.

Yesterday’s birds included a male wheatear on the Lichen Heath and the long-staying Bonaparte’s gull on Ibsley Water.

 

 

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.

Trying to Spring

Spring has stuttered somewhat this week, with the return of night frosts and a chilly northerly wind. With continuing sunny days this has not had too much effect on many species but the cold nights have really hit the moths. Recent days have been seeing just a handful of moths in the trap at most. Some of the highlights have been a couple of great prominent.

And, yesterday a spectacle.

One hazard that we have to watch very closely when checking the moth trap is our resident robin, it has got very tame and will dive in and grab a moth if given the smallest chance.

The sunny days are still good for butterflies and other insects and this spring has been one of the best in recent years to spring insects. One of the typical spring hoverflies, Epistrophe eligans is quite frequent along the wooded paths now.

There are also good numbers of green tiger beetle in the sandier areas of the reserve, these are very active, running fast and flying very readily, a proper challenge to photograph!

On the bird front yesterday saw our first black tern of the year over Ibsley Water, along with the Bonaparte’s gull, little gull and the return of the male ruff first seen on Sunday, but apparently not on Monday.

A Dry Spring

Lots of visitors are coming to the Tern hide at present, drawn in roughly equal measure by the Bonaparte’s gull and great views of the lapwing chicks. The gull was present on and off again yesterday as were 3 little gull (2 of them beautiful adults), up to 27 or more Mediterranean gull and at least a dozen common tern.

The two lapwing chicks in front of the hide are doing well and approaching two weeks old now, this is especially pleasing as they are only protected by their mother, dad having gone missing a while ago. She is driving off all comers, but especially redshank, common sandpiper and little ringed plover, not perhaps the greatest threats to her chicks.

So far lapwing are having a remarkable year and we have something like 20 pairs nesting with at least five already hatched. Of these three can be seen from Tern hide. The lake shore has the lure of water, where the chicks can find small insect prey, but it is not that safe as it is frequented by many predators. They would be better staying around puddles away from the shore, but the recent long bout of dry weather has meant almost all of them have dried out now, we could really do with some rain!

The good weather has been brilliant for early butterflies though; the reserve has had lots of orange-tip and large first broods of speckled wood and small copper.

As spring moves on we are now entering “Willow snow” season, when the woolly seeds of the willows are blown around and collect in drifts. It is these light-weight seeds that allow willows to colonise so well as they are carried long distances by the wind.

Despite the dry weather there have been a few fungi around and I came across the one in the picture below growing on lichen heath on Sunday, I have failed to put a name to it though.

Recent days have seen a good range of birds around the reserve. Both garden warbler and common swift have arrived in numbers and there has been a good variety of migrants. On Sunday a fine male ruff was on Ibsley Water and other passage waders in the last few days have included whimbrel, greenshank, dunlin and common sandpiper.

Catch-up

After a bit of a break, both because I have been away and due to a computer failure I am now back and doing  along overdue post.

Headline news has to go to Blashford’s first Bonaparte’s gull, a North American species, similar to, but slightly smaller than a black-headed gull. I saw it first as I locked up on Monday and then again as I locked up today. It is a first summer bird and seems to come to Ibsley Water late in the afternoon to hunt insects. Here is my “Record shot” of the bird, truly a terrible picture, but with imagination you can just about tell what it is!

The gull is not the only Blashford first recently though. In the late winter we did some clearance of small trees to expose a sandy bank that has been popular with solitary bees and many associated species. When I visited the other day I spotted and photographed a dotted bee-fly, similar to the much commoner bordered bee-fly, but with dots on the wings.

Regular visitors will know that we have been working to improve habitat for nesting lapwing at Blashford and this has included the restoration work on the old concrete block works site. It has certainly paid off and we now have several broods of lapwing chicks running around, including two right in front of the Tern hide, a great opportunity to see them really close if you have never had the chance.
