Open Again

The Tern Hide will be open again today, although there are still some access restrictions elsewhere on the reserve, where works continue, please take note of any signs as works are changing day by day as they are completed. That said all the hides are open, as is the Centre.

The last few days have been as hectic as have many over the last few weeks, although thankfully we are firmly on the home stretch now. Despite a degree of chaos spring is definitely moving along apace.

Chiffchaff and blackcap are now present in good numbers and we have also have the first reed warbler and willow warbler on the reserve. Over Ibsley Water large numbers of sand martin, house martin and swallow have been gathering and some sand martin are now visiting the nesting wall. There have also been migrants passing through, the week has been characterised by a significant movement of little gull, with up to 12 over Ibsley Water at times, on their way to breeding areas around the Baltic Sea.

A proportion of the swallows and martins will be moving on as will be the splendid male yellow wagtail that was seen on Thursday.

Insect numbers are increasing also with many more butterflies around.

As well as the species that hibernate as adults there are also lots of spring hatching species too, particularly speckled wood and orange-tip.

The nights, although rather cool have more moths now, on Friday morning the highlight in the moth trap was the first great prominent of the year.

Earlier in the week a red sword-grass was a notable capture, possibly a migrant but also perhaps from the nearby New Forest which is one of the few areas in southern England with a significant population.

I have also seem my first tree bumble-bee of the year, a queen searching for a nest site, this species only colonised the UK in the last 20 years, but is now common across large areas.

Of course all the while resident species are starting to nest, blue tit and great tit are starting to lay eggs and I have seen my first song thrush fledgling of the year. Out on Ibsley Water lapwing and little ringed plover are displaying, truly spring has arrived at Blashford Lakes.

30 Days Wild – Day 14

Some days are wilder than others, even when you work on a nature reserve. Today was not one of the wildest, the morning was spent in a meeting, where wildlife was a topic rather than present and the afternoon was largely taken up with trimming paths with the help of our volunteers. During path trimming we saw a few common spotted orchid and broad-leaved helleborine, I looked for twayblade and southern marsh orchid, both of which I have seen in the same area before but without success.

It was warming up as we finished and on the way back to the Centre we saw a red admiral and a male large white. Butterflies are very few and far between at present, but soon the browns will be out and this should change.

As I went to lock up the sun was almost out and near the Woodland hide the orange-tip caterpillars were doing their best to look like the garlic mustard seedpods upon which they feed.

When I first saw these I discounted them as orange-tip, because they were not green, forgetting that they look quite different in their first few instars.

On the way down to the Ivy South hide is found a tree bumblebee sunning itself on a bramble leaf. This is a species that ha sonly colonised this country in this century, but is already common throughout most of England. It is similar to the common carder bee but the white tail gives it away.

Finally caught up, I just have to keep going to the end of the month now!

Mellow Yellow Day

It rained quite heavily overnight but was clearing as I arrived and I had a hope that it would, as we expect, clear in time for the volunteers work party. In fact it did and fifteen, more or less willing volunteers set off to start the annual task of controlling ragwort. On a site like Blashford on dry soils with a long history of disturbance total control will be impossible, the seed bank must be enormous and will last for tens if not hundreds of years. Despite this we do try to control growth along the boundaries where there is seen to be a problem with spread onto grazing land. Today we started on the western side of Ellingham Lake, the conditions were fine to start with but then deteriorated and suddenly the plants growing under the trees became the target of special effort. There was a short discussion about calling it a day, but Blashford volunteers are made of stern stuff and we carried on and then the rain stopped and we completed the whole length.

We walked back past Ellingham Inlet Pound, the very short vegetation around the eastern end has a lichen heath character, but includes some species not out on the main area of heath near Ivy Lake including one that was very striking in today’s dull light, the brilliant yellow biting stonecrop.

The rain returned for quite a bit off the afternoon and kept going right until the visiting school group left, when the sun came out! In the brief warm spell I noticed several tree bumblebee workers feeding at the flowers of the dark mullein near the Centre. The picture also highlights the amazing colour of the flowers.

The tree bumblebee is a recent colonist from the Continent and is now spreading rapidly northwards, last year we had a nest near the Centre in a bird box. On the same mullein plants there were also a few caterpillars of mullein moth, at this stage they seem to be eating the flowers rather than the leaves.

I had another good look at the common tern rafts again today and am now more or less certain that there are twenty-one pairs nesting now, sixteen with chicks and a further five late nesters on eggs. A good few of the chicks would be flying within a week, so it looks like it should be another good nesting season for them.
