Cetti's highlights one of the best-ever 'clear' migration mornings

Heysham Obs
Considering we were late (traffic again!) and missed the early thrushes, this was quite an impressive morning which included a new bird for Heysham NR; far better than chasing the stars and disappearing bird(s) along the dreaded Washway/A149.  Thanks to Sean and friends for coastal coverage, including the 'in-off' Blue Tits!

Vis mig by the office 0715 onwards

CETTI'S WARBLER - on weight & wing measurements definitely a female, considered 1CY

Miscellany
Twite - c6 on the mound
Med Gull - three adult and single 2CY and 1CY

Insects
at least 15 Red Admiral seen flying south.  One very worn Speckled Wood and two "off-passage" Red Admiral.  c10 Common Darter at the back of the wetland but no sign of any Migrant Hawker.  One Large Wainscot was the only occupant of the moth trap (the element of east in the overnight wind suppressing the catch)
