A perhaps unexpected AA morning

Heysham Obs
Ringing/vis from dawn for an hour or two today with the aim to catch some pre-dawn thrushes, then the finch passage.  A nocturnal unringed (therefore just landfalled?) Wren in a mist net set the tone of the morning which saw a chunk of "AA" rings used on common birds and conversely relatively few Blackbird and Chaffinch in evidence today.  The low point of the morning was the first evidence of obvious trichomonosis this autumn (500+ finches handled) on a fairly old retrap Greenfinch - this was released immediately it was extracted and the number noted.  Less numbers but quite a bit of variety on the vis mig today with more of a cross-bay corridor than recent days
