Counting Day

Once a month we count the wildfowl on the reserve and also on the other lakes in the area to get an idea of how many there are and so how populations are fairing. Wildfowl are counted right across NW Europe once a month during the autumn and winter and this provides estimates of total populations and changes. In Britain the Wetland Bird Survey (WeBS counts) started in 1969 and now covers all our estuaries and inland wetlands. The counts we do of the lakes are actually in addition to the WeBS counts as we cover only the lakes, the full counts are co-ordinated along the whole valley from Christchurch Harbour northwards.

I started by counting Ibsley Water and from the Lapwing hide was greeted by the sight of a flock of wigeon grazing just in front of the hide.

Despite this overall numbers of birds on the lake were not very large, probably due to a combination of relatively poor weed growth and the rather strong wind. One a factor that will depress numbers throughout this winter the other just weather, which can make a great difference to where the birds will be from day to day. Although not a bird for the count, I was pleased to see the water pipit on the cut grass heaps on the lakeshore, digging in the grass for insects.

The total number of waterfowl counted on all the lakes combined was just under 3900, not bad for November as the peak usually comes around mid-winter, so there is time for it to rise yet. The most numerous species were coot 976, wigeon 936, gadwall 521, tufted duck 291 and shoveler 261. Different lakes provide conditions for different species and we also find that factors like weed growth vary greatly from year to year and in different lakes. This year weed growth in Ibsley Water is quite poor, but it has been good in Rockford Lake and Blashford Lake and it is these lakes are attracting the large numbers of coot, gadwall and wigeon as a result. Ibsley Water seems especially attractive to pochard just now with 72 there today, whereas Mockbeggar Lake is shoveler central, with over 200 feeding on there and probably more, as it is a difficult to see through the trees from the path to Lapwing hide.

Although I missed them it seems probable that both great white egret were seen today, I may have seen both actually as I saw white birds though trees where they should have been! The bittern was also seen briefly from Ivy North hide and on one of the lakes north of the reserve I saw the ferruginous duck. This bird has been returning for some years and favours Kingfisher Lake on the outskirts of Ringwood, but this lake cannot be viewed as it once could. So far this winter though it has made one trip to Ivy Lake and today it was visible from the public footpath north of Mockbeggar Lane on the larger of the two lakes there. Hopefully it will oblige and spend more time in places where it can be seen, it is certainly worth checking the diving ducks on any of the lakes, just in case. I understand that the ring-billed gull put in an appearance on Ibsley Water in the afternoon, I suspect we will see it until the spring now.

I heard earlier this week that a car was broken into in one of the car parks last week, thankfully a rare thing at Blashford, this is only the second time it has happened, but it would be wise to take care not to leave valuables on show, or ideally in your car at all.

  1. I thought you might like this image I took of the Great White Egret (appears not to be ringed) flying across the front of Ivy North Hide yesterday at about 15.00
