Oh, to Bee in England…

As though to emphasise the change in season today was one of those rare days when it was possible to see both brambling and swift at Blashford Lakes an opportunity that lasts for only a few days.  When I started birdwatching in the Midlands our equivalent was seeing fieldfare and swallow in the same place, on the same day. The brambling were at least 2 males at the feeders and the swift at least 14 over Ibsley Water.

Despite the remaining reminders of winter it felt very spring-like, with orange-tip, green-veined and small white, comma, peacock, brimstone, holly blue and several speckled wood butterflies seen, along with the year’s first damselfly, the large red.

After last night’s thunder storm I was not surprised that the moth trap was not over-filled with moths, although the catch did include a lesser swallow prominent, a pale prominent and a scarce prominent, the last a new reserve record, I think.

The warm weather has encouraged a lot of insects out, I saw my first dark bush cricket nymph of the year near the Centre pond. Nearby I also saw my first dotted bee-fly, this species used to be quite scarce but can now be seen widely around the reserve, although it is well outnumbered by the commoner dark-bordered bee-fly.

The wild daffodil are now well and truly over but the bluebell are just coming out.

A lot of trees are in flower now or are shortly to be, the large elm on the way to Tern hide is still covered in flower though.

Trees are a valuable source of food for a lot of insects and the find of the day was a species that makes good use of tree pollen. I had spotted what I at first thought were some nesting ashy mining bees Andrena cineraria, but they did not look right. That species has a dark band over the thorax and black leg hairs. This one had white hairs on the back legs and no dark thorax band. I took some pictures and it turns out to be grey-backed mining bee Andrena vaga, until very recently a very rare species in the UK which seems to now be colonising new areas.

They make tunnelled nests in dry soil and provision them with pollen from willows for the larvae.

The same area of ground also had several other mining bees, including the perhaps the most frequent early spring species, the yellow-legged mining bee.

Common terns vs. blackheaded gulls – and other news

A beautiful morning this morning – the above picture of a mill pool calm Ibsley Water in  morning sunshine is not a view that we have been able to enjoy many of over the last year or so! A redshank was patroling along the shore when I opened up, but was quickly seen off by a territorial lapwing. A few minutes later the same lapwing put up this little ringed plover which conveniently flew closer to, rather than further away from, the hide:

Unfortunately there was no sign of the otter which someone has recorded as having seen from Lapwing Hide earlier in the week. I await my first view patiently!

The black headed gull colony seems to be doing very well – to the extent that, coupled with the unusually high water levels, nesting sites are at a premium and they are therefore seeking out new alternative sites both around Ibsley Water itself and elsewhere.

Unfortunately one of the “elsewheres” are the tern rafts deployed out on Ivy Lake. Two went out on Monday this week and the remainder on Thursday – on both occasions they were immediately descended upon by the common terns who have clearly been on the look out for them since they arrived and were no doubt perplexed by their absence before-hand. They are not made of as stern a stuff as in previous years though and on both occasions by the following morning they have been supplanted by the black headed gulls. However six plucky terns have stuck to their guns and so far are holding their own against a single pair of gulls on the left-most raft and this morning their were another 3 pairs of terns hanging around looking hopefull so with a bit of luck they’ll pluck up the courage to gang up and see off the interloping pair and perhaps even the rest that are currently monopolising the other rafts. At least one of the pairs of terns on the raft were mating this morning, so they mean business!

Other recent news on the bird front is an update from the BTO ringers running the CES site on the reserve who were pleased to ring their first willow warbler of the year (pictured below, thanks to Kevin Sayer):

Also caught and rung were: Reed Warbler 19, Reed Bunting 6, Garden Warbler  1, Great Tit 1, Blackbird 4, Long-tailed Tit 2, Blue Tit 1. Particularly exciting news from the ringing team were reports of what appeared to be a whitethroat territory, which if it was and they do nest, is possibly the first record of nesting whitethroat for the reserve.

I was out until dark digging over a much neglected allotment last night and being well and truly “midged” so I was  anticipating a bumper moth catch this morning – or at least more moths than there have been of late. I was therefore disapointed to find just two hebrew character, one flameshoulder, one common quaker and one lesser swallow prominent (flameshoulder and prominent pictured below):

Also in the trap, and the first of the year for me, if not the reserve, was a single May bug:

In the pond a lovely grass snake (other visitors photographed a grass snake eating a toad in the reed/scub between Lapwing and Goosander Hides today):

And the bluebells are looking (and smelling!) wonderful all along the Dockens Water:

The wonderful and uniquely British bluebell wood!

There are lots of woods with more extravagant displays of bluebells than Blashford Lakes, but even so I look forward to seeing them every year. One of the best (if not the best!) places to enjoy bluebells locally is the Trusts Roydon Woods Nature Reserve between Lymington and Brockenhurst which I will be heading to soon with the family!

Sadly not everyone who visits our Nature Reserves do so with the same sense of awe, wonder and responsibility as we do. Ed and I had the unpleasant task of removing the fly-tipped waste (apparently the contents of a house clearance judging by the amount and type of assorted rubbish that had been dumped) left by one such visitor. No doubt tipped by a “business” involved in commercial removal of domestic waste for a ludicrously cheap price who avoids paying any waste trasfer duty (and no doubt saves a bit of diesel) by dumping in the nearest secluded green space – then to be removed at the expense of the landowner unfortunate enough to be the recipient of the rubbish, in this case us. Fortunately there were no farm animal carcasses or asbestos dumped this time, but sadly that is not an uncommon occurence either.

Here’s Ed with what was a very full trailer of rubbish at the end of the day yesterday (we were both as disgusted as he looks):

Bird News: Ibsley Watercommon tern 4, swallow 30+, house martin c10.

Not quite so cold last night and the usual moths were supplemented by a waved umber and a lesser swallow prominent. The waved umber flew off, which was a shame as they are very fine but the prominent was prepared to pose for a picture.

After yesterday’s excitement I was prepared for a day in the office, with no machinery most jobs out on the reserve were out of question. There was the securing of the stores to get done but that was in the hands of a contractor, so a day indoors was what was stretching out before me. However, just after I arrived the power went off and it remained that way throughout the morning, desperate measures were called for and Jim had to get the storm kettle out so we could make a cup of tea! These are incredibly efficient and it is a real eye-opener how few twigs it took to boil enough water for three mugs of tea, it was also very quick, once it was alight.

Jim making tea, or he will be when the fire lights!

The morning, indeed much of the day, was actually spent dealing with the aftermath of the break-in or getting to the bottom of our lack of power, the latter was eventually traced to a problem in the water treatment works. Crossing towards the plant I noticed a good show of the tiny changing forget-me-not, so-called because the flowers change colour as they mature. Each flower is about 2mm across and the whole plant only about 25-30mm tall, or short!

changing forget-me-not

I do not know why the flowers change colour, but as a bit of pre speculation I propose that it might be to maximise the number of potential pollinators, different species are attracted to different colours and for an annual plant that flowers early in the year hedging your bets as to which pollinators are out and about might not be a bad tactic.

When I went to lock the hides I also checked out some areas that we had cleared during the winter and took a few pictures to update the record of habitat development. One such area is beside Ivy lake where we cleared willow scrub to try to reinstate reed swamp. So far I am pleased with the progress, although it will take another two or three years before we will know just what we will get. There were some heavy showers around at the time and one had just missed Blashford when I took the picture.

When I went to close the Tern hide there were modest numbers of swallows and martins over the lake and a couple of common terns, although four had been reported earlier, as had at least one goldeneye. With the heavy showers I had half expected there to be a few migrants forced down, still maybe tomorrow…
