The first six months

After having our 2nd best start to the year last year with 1400 birds ringed by the end of June we were hoping for a similar start this year so by achieving a total of 1391 we have done really well when you
consider the incessant wind we have had to endure from the North. This has made things quite difficult for us as our site is quite exposed when the wind is from this direction. However we have persevered and
achieved better results than it felt. Surprisingly we caught exactly the same number of species as last year with 39 although 9 of these were different to last year. It's been a real funny year with most species being caught in smaller numbers than last year, some of which are really unexplainable. Wren and Robin have been caught in similar numbers but Dunnocks are down from 43 last year to 24 this year. The Tits are a bit up and down with Blue Tit up from 231 to 294 and Great Tits remaining static whist Long tailed tits are down from 42 to 25. Tree sparrows have increased dramatically from 141 to 234 .... a brilliant increase in numbers!
Apart from Chaffinch, all finches have shown a dramatic decrease in numbers with Bullfinch and Linnet being the worst with a 75% decrease. The warblers are all over the place with Reed and Sedge showing big
increases while Lesser Whitethroat ,Blackcap, Chiffchaff and Willow warbler showing the opposite with big decreases. Whitethroat and Garden warbler numbers look stable. This year has also seen a new breeding species for the reservoir with up to 3 breeding female Cetti's Warblers caught since May and three 1j's caught over the last 2 weeks, so overall not to bad a start to the year.
