18 Twite trapped, including 7 unringed birds, out of 30+ seen. The retrap data is interesting. Most of them were retrapped for the first time since ringing with the ringing dates as follows: 31/10/08 (1), 5/11/08 (2), 26/11/08 (4) and 4/2/09 (1). One was ringed on 5/11 and retrapped on 4/2/09. Two others were both ringed on 31/10/08 and retrapped on 5/11/08 + 16/11/08 and 16/11/08 + 15/12/08 respectively. Bearing in mind that only FIVE out of the 137 ringed during winter 2008/9 have been previously retrapped twice, it is interesting that two of these have appeared for their third retrap today. This suggests that, in contrast to the rest of the retrap data (& unringed birds), which suggests a wide-ranging metapopulation with individual birds occasionally visiting Heysham, these two have developed a degree of loyalty to the Heysham feeding station.
