'I have a BTO approved
project to colour ring winter Blackcap in my garden to determine amongst other
things how long specific birds stay in a particular area. This season I colour
ringed 4 in December, none of which I have seen again, and 2 so far in
February. In the very mild intervening period I only recorded 1 unringed bird
in January. Doubtless the current influx of birds is as a result of the very
cold weather coming from Siberia and I am aware that many people in S Cambs are
recording them in their gardens at the moment.
To expect one external
record of these birds is ambitious to say the least but I would like to raise
awareness to at least shorten the odds.
Please
report colour ringed birds to the BTO.' RI
