Another busy day with lots of visitors, a volunteer work party and the Pop-up cafe. The bittern performed from time to time at Ivy North hide, including at dusk as I went to lock up. A water rail there was seen to catch and eat a small fish, which surprised some watching, in fact water rail are not fussy eaters and will happily eat vegetation, seed, and animal matter alive and dead. I have seen them eat fish and even small birds and they are a well known hazard when ringing birds in a reedbed, as they will try to pick birds from the nets given half a chance.
The volunteers worked laying another section of the hedge alongside the A338 on the western side of Ellingham Drove. This hedge was planted in 2005/06 winter and is being laid to thicken it up and make it more useful for wildlife and as a visual screen for the road.

After the hedge laying you can see it is already much denser even though some of the side branches have been removed.

Those of you that are familiar with the traditional craft of hedge laying will immediately notice that this is not a craftsman’s job. The traditional craft produced a barrier that would keep livestock in before the days of barbed wire, it had a woven line of rods on top between stakes and much more of the twigs and branches were removed. This art is still practised and there are regular competitions, to make a good traditional hedge in this way takes great skill. However we are just trying to thicken up the hedge and retain as much of the potential for flowering and fruiting next year and for this purpose some reduction in the branches and a partial cut to lay the stem over will suffice.
Such hedges make good nesting places for many of our common birds like robin, dunnock and blackbird.

This hedge is almost entirely made up of hawthorn, but we are trying to diversify it by adding extra species. One that we could add is hazel, normally we would plant these in the winter when the plants are dormant, but looking at the hazel around the reserve today they are anything but dormant.
The catkins are the familiar flowers of the hazel, but these just the male flowers which open to scatter their pollen, the female flowers are much smaller and easily overlooked. Each hazel will have flowers of both sexes, the catkins on the ends of the twigs and the female flowers a little further down.

Although winter is natures “downtime” it is not so for all species and on the outside of the Education Centre door this morning there was a male winter moth.

When moth trapping you always catch many more males than females, probably because they fly around more seeking females, however in the case of the winter moth you will only ever catch males as the females are wingless. The larvae to these moths eat oak leaves are the main food collected by blue and great tit when feeding their young, one of the possible effects of climate change could be a disconnect between the timing of peak caterpillar numbers and hungry chicks. Only time and project s such as the one undertaken by Brenda at Blashford (see the last post) will show if this becomes a real problem for the birds.
I was trying out a new camera today, a replacement for my one that packed up the other day, it is a “bridge camera”, not something I have used before so I was keen to see what it could do. The light was not good today, but it seems as though it will be useful. I tried a range of pictures, standard shots a sat the top of the page, some macro and finally some using the full magnification, although not a great shot I quiet liked the one below of a group of pintail.

Hopefully we will get some better light and I will get the chance to put it through its paces rather more fully.
