I opened up the hides at Blashford this morning in a fog that meant I could see only a few hazy birds looming in and out of the mist. The sun looked like it might break through, but in fact it took until nearly midday and then we had banks of cloud from time to time. The volunteers tried to do the butterfly transect and just about managed it, although butterflies were few in number.
When the sun did come out at lunchtime I took a walk by the lichen heath, this is a fascinating and very vulnerable bit of habitat, the lichens do not like being walked on, so I kept off the heath proper. The habitat owes its existence to the ultra-poor soil which has just enough nutrients for lichens and mosses and a few very, very small flowering plants. Amongst them two or more species of speedwells.
Most speedwells are small plants, this one, wall speedwell, is very small with flowers perhaps 2mm across. I also found a patch of blinks, I seem to remember being told that it was the UK’s smallest flowering plant.
There are also several forget-me-not species, two of which are especially small.
This one is early forget-me-not and has flowers about 2mm across, they are a traditional forget-me-not blue, as might be expected. The other tiny species is quite remarkable in that it cannot decide what colour the flowers should be, or rather it has flowers that change colour as the age, it is the aptly named changing forget-me-not.
The heath is also home to a wide range of small insects and other invertebrates, a surprising number of them seem to be either ants or spiders. I came across a number of small mounds of sand, well actually many were more like chimneys, made of sand grains pile dup and with a hole down the centre. They were evidently entrance ways into ant nests as there were ants clearly visible around the entrances. Although I describe them as entrances there did not seem to be many ants coming and going so perhaps, like termites they build them as part of an air circulation system.
My last find of interest out on the heath was a small moth, now I have had trouble identifying it with anything like certainty, I am pretty sure it is a Gelechid of some sort, my best guess is Aroga velocella, which has larvae that eat sheep’s sorrel.
Walking round the edge of the heath I passed a Scots pine and noticed it was in flower, the male flowers release huge amounts of wind-blown pollen which fertilise the female comes, each tree is both male and female, as you can see from the picture, the large males flowers are above the smaller female cone.
Looking closely at the flowers I realised that many of them had a spider on them, the same species every time and seemingly only one on each flower cluster, they were also quite well camouflaged. I have failed to identify the species, if anyone can help I would be very pleased.
On my way back to the office I stopped by the handful of ramsons I found the other week, a plant I had not known even grew at Blashford. They are now in flower and I took a couple of pictures and in one I saw that the flowers were being visited by ants, presumably feeding on the nectar.
Although the sun was not out for long it did feel quite spring-like and warm, a calling cuckoo added to the feel as did 2 swifts which flew over. The 2 or 3 calling Mediterranean gull that circled over made for a rather more seaside feel, but all in all it was very pleasant.
Other birds about today were about 30 common tern, good news as we will be putting out some tern rafts tomorrow and I would like them to be fully occupied as soon as possible to stop the black-headed gulls taking over.
