30 Days Wild – Day 13: Gulls get Rings

Tuesday is one of our two regular volunteer days at Blashford Lakes, this week’s main task was further work to improve the grassland habitat along the western shore of Ibsley Water. We have had a long-term project to remove bramble, nettle and willow that has been threatening to take dominate. This shore was remodelled into a steep bank using the topsoil removed from the gravel pit surface when it was first dug, conditions ideal for the development of nettle beds and bramble thickets. To reverse this we have been mowing to allow grass and perennial herb species to get the upper-hand.  This has been targeted work aiming to take out only the least desirable species. Even the nettle beds have elements that we leave, such as any patches with nets of peacock and small tortoiseshell larvae.

Alongside the nutrient-rich soils there are poorer patches and these have a more interesting flora including a number of bee orchid.

At the end of the day I went out to Gull Island in Ibsley Water with the bird-ringers to colour-ring a sample of the black-headed gull chicks. We have been doing this for a number of years to find out where the birds from this recently established colony go to and if the chicks reared here return to breed in later years. We managed to catch and ring thirty chicks during our short visit, a good sample.

209C gets a ring, where will it go and will it come back?

In the evening I came across a female stag beetle on the fence in the garden, the first female I have seen this year. The day ended on a fine calm note and so I decided to head out to listen to the nightjar again. One came and perched on a branch very close by and gave great views. I never tire of watching and listening to nightjar and to have the opportunity to do so just a few minutes walk from home is wonderful.

Ringing in the New

Despite the weather being somewhat poorer than originally expected the reserve was busy with a mixture of general visitors and listers out to get a good start to 2016. I knew it would be, as there are several species that you are more perhaps likely to see at Blashford than anywhere else in Hampshire. Species like brambling, and two obliged for much of the day at the Woodland hide, Slavonian and black-necked grebe, which both showed all day on Ibsley Water and of course goosander and goldeneye. Then there are the gulls, with regular yellow-legged gulls and, albeit rather late in the day, the ring-billed gull. The only species that really let the side down was bittern, which failed to show at all, as far as I know.

I managed to see 66 species of birds on the reserve today, not a bad start to the year. Along the way I found a hibernating peacock butterfly and a very well developed group of orchid rosettes, hopefully they will cope with any frosts we do eventually get.orchid

I had the rather pleasant task of putting the new hide logbooks in each hide today, so I got to visit them all. From the Goosander hide it was pleasing to see a group of wigeon grazing the eastern shore of Ibsley Water, just reward for all the volunteers’ hard work.grazing wigeon

I also saw a colour-ringed first winter black-headed gull standing on the rails, I think it was a red ring coded 230A, but it was hard to be sure, can you make it out?ringed black-headed gull

The recent rain has also been beneficial to the ephemeral ponds, these only hold water for part of the year, but have a whole range of specialist species that depend upon them. The volunteers have been involved with these too, treading the mud in the bases so they hold water for longer, a process known as puddling. temporary ponds

As well as a good range of species there were a few notable counts during the day, mostly at dusk. I could not get into the Tern hide, there was such a crush of gull watchers, so I looked from the mound at the back of the car park. From there I saw the ring-billed gull and, after a long absence, a flock of starling. Not quite a fully fledged murmuration , but at least 3000 birds. Later on Ivy Lake there were at least 161 roosting cormorant, a new record. I also counted 239 tufted duck, a large number, but there must have been many more as I could mostly only make out the drakes with their white flanks as it was so dark.
