The Beeston ringing year was bought to a close on a cold December morning. At one point snow flurries caused the nets to be furled for a short time.
Food provided in both the garden and John's Copse attracted a number finches and tits. Two Reed Buntings were a welcome surprise and we ringed the first House Sparrow since May.
The 33 new birds ringed took the year total to 408 - a new record, beating the 373 birds ringed in 2008. Greenfinches topped the charts with 109 ringed during the year, almost a quarter of the total for this species ringed at Beeston.

Repeat offenders
A total of 37 retraps (birds we've already ringed) in a single session is one of the highest that we have ever had at Beeston. Only 17 of these birds were ringed in 2011.
A small party of Long-tailed Tits were caught, with five of the six already ringed. We were happy to see after two very cold harsh winters that two individuals had survived both winters - tough little birds weighing around 7.5g. They were ringed on the same day in November 2008 and caught together in February 2009.
The time between original ringing and this recapture was 3 years and 33 days, which represents a record for this species at Beeston. The others were ringed in February, May and October 2010 respectively.
Wren CHC761 was originally ringed in August 2008; the only subsequently recapture was in March 2009, so quite where the bird has been in the past three years is anyone's guess.
Of the 16 Blue Tits retrapped, just over half were from the 2011 ringing sessions, three from 2010 and two from 2009 and T959658 was retrapped six years to the day after it was ringed in 2005. The bird had been recaptured 4 times previously; the latest being in March 2011.
Of the Great Tit retraps, we were pleased to see one of our 'repeat offenders' for the 11th time! The bird with ring X404410 was originally ringed as a young female in November 2008.
Of the finches retrapped, two Greenfinches and two Chaffinches were from 2011 sessions. One of each species were ringed in 2009 - a Greenfinch from March and a Chaffinch from October of that year. Neither bird had been retrapped in over two years since ringing.
It's such findings that make bird ringing so fascinating. We learn a bit more about how birds survive such hardships as weather and why we see some birds more often than others...
January preview
Weather permitting we'll start the new year at Beeston with a ringing session in the middle of the month. The Copse and garden will again be our focus with seed provided to attract finches and buntings into the area.
January usually represents one of the busiest months regarding new bird captures, possibly due to the reduction in natural food available as these becomes depleted as winter progresses.
Previous January catches have seen good numbers of Greenfinch and Chaffinch as well as Beeston rarities such as Bullfinch, Linnet, Siskin and three of the five Green woodpeckers ringed have been in January.
