TUESDAY 8 JUNE

All morning long, heavy rain fell, leaving little opportunity for birding. It eventually cleared away to the east, giving rise to the occasional heavy shower, but remained fairly warm with light winds. I utilised the afternoon and evening by surveying........

TRING RESERVOIRS (HERTFORDSHIRE)

TOTTERNHOE KNOLLS (BEDFORDSHIRE)
(Evening visit)

A REAL TREAT. Despite the heavy rain showers, walking along the muddy footpath adjacent to the Lime and Stone Company in Limekiln Lane and beyond the numerous MAN ORCHIDS to the overgrown lime pits, I was absolutely delighted to find 4 different 'purring' and displaying male EUROPEAN TURTLE DOVES in the scrub thereabouts. Francis Buckle, Roy Nye and Dave Bilcock had visited previously and very kindly tipped me off of their presence - such gorgeous birds and fabulous to see so many locally.

The scrub also held several pairs of Stock Dove whilst singing male CORN BUNTINGS were seen here and in neighbouring Wellhead Lane in Toddington village (5 janglers in total).
