More successful Twite ringing

Heysham Obs
North harbour wall
Song Thrush - 1
Twite - 30 were caught of which 18 were already Heysham-ringed, including quite a few birds from previous years.  Perhaps surprisingly, there were 12 unringed birds, marginally more than have been seen in the field recently.  There was at least one small flock which was not caught and ringed, nor examined in the field for ringed/unringed ratios.  The wary behaviour of this flock and observations on previous days suggests that possibly all the current Twite have now been ringed.  Will be interesting to see if any more unringed birds materialise this winter
Goldfinch - one unringed bird caught plus a few retraps
Linnet - one retrap, possibly more around as light very bad for speciating Linnet/Twite in the field
Med Gull - 2CY
Nothing of any interest seen offshore and no Meadow or Rock Pipit sightings reported
