Back working at Blashford Lakes today, this morning with the first Sunday of the month volunteers. Only a small turnout today but we spent the time working around the new dipping pond, covering up the exposed liner and generally trying to make it look more like a “real” pond. As we were working I noticed some of the plants that had grown up on the exposed soil thrown up when the pond was dug and amongst the plants were several of common fumitory.
This is a species that was once an abundant “weed” of cultivation, typical of the margins of arable fields. Some thirty years ago it was noticed that the distribution of turtle dove and fumitory were very similar in Devon, this gave rise to the idea that perhaps the doves needed the plant. However it turned out that it was more that they both needed the same habitat, it was a correlation, both depended upon there being a bit of space left for them between the intensive arable.
The hemlock water-dropwort growing beside the old pond is now in full flower and is usually a really good nectar source for lots of insects, so far this year I have not seen nearly as many as I would expect. However today there were at least a few hoverflies to be seen on the flowers.
The warm night resulted in much the best moth catch of the year so far, with 34 species including a privet hawk-moth, poplar hawk-moth, pale tussock, Brussels Lace and this alder moth.
Almost immaculate, apart form a slightly rubbed thorax.
As I went to lock up the Tern hide looking out over Ibsley Water I saw a tern in the distance that did not “look right” and no wonder, it was a little tern, in fact there were two of them. Typically very much coastal terns in the UK, so it is always a treat to see them inland, or increasingly anywhere these days, as they are one of our most threatened seabirds.
