Roger Wyatt very kindly emailed me these images of MEXICAN HOUSE FINCHES in Mexico - the natural variety.
This morning, the yellow variant Land's End Mexican House Finch has relocated to South Devon, where it has been singing from the roof of a house by the village green in East Prawle (from 0730-1230 hours at least). Whether the bird is an escape or a ship-assisted vagrant is still open to conjecture (Lee Evans)
