The first whoosh netting attempt of the Autumn for Twite at Heysham Harbour this morning. A few Twite have been present over the last week, together with Goldfinch and Linnets.
This morning's session saw 41 new + 1 retrap Goldfinch, 2 new + 1 retrap Linnet and 5 Twite captured. Almost 50% of the Goldfinch were aged as still being 3J, notwithstanding the lateness of the season.
The colour combination in use for Twite on the left leg below is Red/Blue split colour over Pale Blue plain (on the right leg BTO metal only).
We would ask any observers finding Twite in the area to look out for colour rings and, if possible, report an estimate of the ringed/unringed ratio of birds in the flock together with colour combinations if they can be seen. The split colours can be hard to read in the field but the plain colour itself indicates the ringing site (i.e. Pale Blue for Heysham, Yellow for Duddon Estuary etc.) so reading this colour alone is very useful.
