Where once were many Tree Sparrows
This morning saw me teaming up with Beddington-birder Steve Thomas - a key-holder to the magic kingdom of the farmlands! After Tuesday's panic to see the Glaucous Gull today was a far more leisurely affair. The gull was once again present (on the tip and north lake). The morning's main quest was to hunt down a Tree Sparrow, something that could be done with little effort just a few years ago at Beddington. But times change, and the sewage farm population has fallen, and with it the number of over-wintering birds. We saw just the one, feeding on red millet at a bird feeding station (photo above taken a few years ago). Below is a summary of my personal records for the Uber-patch to add some context.
First recorded at Beddington SF and River Mole, Leatherhead (1975), Seears Park, Cheam (1983), Holmethorpe (1991). The breeding colony at Beddington SF is (or was) well-known, and counts could be high throughout the year, with a peak of 200 recorded on 25 February, 22 March and 26 November 1978. However, by the end of 2012, counts were much lower, sometimes only 20+ being made and by 2014 reports were that numbers had plummeted. At Holmethorpe, between 1991 – 1997, this species was not unexpected, but not quite annual, with a peak count of 25 on 25 January 1997. Since the latter date there has been only one further record, a single on 9 April 2005.
My highest count in the UK was of 820 moving north-west on 17th October 1983 at Dungeness in Kent. Such numbers now are the stuff of fantasy.
