Reports and a Bit of Garden Wildlife

5th October reports from Blashford showed that all the main player are still present. On Ibsley Water the ferruginous duck was still around the north end of the Long Spit visible from either or both of Tern  and Goosander hides. The wood sandpiper seems to have relocated to the shore near Lapwing hide, with both common and green sandpipers also still present to “complete the set”. A few wigeon and a single pintail are mingling with the wildfowl and it is worth checking for the occasionally reported juvenile garganey. Both great white egret and several little egret were also about.

Over on Ivy Lake the bittern was seen on the edge of the reeds near Ivy North hide, viewed from the screen along the path between Ivy Lake and Rockford Lake.

I was not at Blashford myself so my wildlife sightings were restricted to my garden and especially the moth trap, a mild, calm, damp night resulted in a good catch of autumnal species.

angle shades

The angle shades is perhaps the moth most adapted to hiding in piles of dead leaves and a species that can be seen as an adult all through the year.

dark sword-grass

The dark sword-grass is a migrant and although they can turn up at almost anytime, they are mush more frequent in autumn.

deep-brown dart

Whilst some autumn moths are yellow to hide in autumn leaves, others just go down the very dull and unobtrusive route, the deep-brown dart is one such species.

feathered ranunculus

Feathered ranunculus is an autumn species that lives mainly around the coasts on cliffs. It colonised the mainland coast of Hampshire in the late 1970s. I remember this well as I was working at Titchfield Haven at the time and caught a number of them, indicating that there were established on the mainland and not just wandering from the Isle of Wight.

southern chestnut

The southern chestnut was first discovered in Britain in 1990 in Sussex. At the time it was considered that it had previously been overlooked, this may be so, but what is certain is that it has increased greatly since and is now quiet frequent across the New Forest heaths and in similar habitat elsewhere in southern England.

Other species in the trap included large yellow underwing, lesser yellow underwing, lunar underwing, willow beauty, shuttle-shaped dart, black rustic, turnip, sallow, pine carpet, spruce carpet, cypress carpet, square-spot rustic and broad-bordered yellow underwing.

I have recently found a new species in my garden, a most unusual plant, called yellow dodder. The dodders are parasitic plants that have roots only as small seedlings and once their tendrils have found a host the tap into the plant to gain all their nutrients and do away with their own roots. There are native species of dodder that can be seen on gorse and heather plants, especially in the New Forest, yellow dodder is not a native and comes from the Americas, almost certainly with bird seed and most likely in nyger seed and this plant was climbing up a self-seeded nyger plant, supporting this idea.

Emerging

Looking in the sweep meadow I spotted a yellow rattle seedling just poking up form the surrounding vegetation. These grow very quickly at this time of year no doubt helped by the fact that they get energy both from photosynthesis in their green leaves and the parasitic tapping of the roots of neighbouring plants.

Their parasitic habit reduces growth in other plants allowing them and other plants that struggle to compete with vigorous species, to thrive. For this reason it is often added to wildflower mixes as it often parasites grasses. For the same reason it was hated in hayfields, where it greatly reduced the growth of the grass crop.

OI posted about the discovery of the grey-backed mining bee at Blashford the other day, this still very rare species in the UK depends upon willow pollen for food and suitable ground in which to dig a nest, Blashford has lots of both. The nest tunnel is more or less vertical  and, to judge by the amount of spoil, quite deep. I got this series of pictures of one emerging from a bit of excavating.
