Nature notes
Plenty of hirundines above our village early in the month, most days to about 10th saw 40 -50 mix of H Martin and Swallow feeding above the gardens, so nice what with the Swifts long gone and little bird song now.
Thu 10th Chiffchaff singing Longwood, heard one briefly last week as well.
Sat 12th Llwyndrissi foresty, quite a few Swallow and a few H martin feeding, lovely watching a group of swallow over the hill slope (Nightjar one) when a falcon disturbed them (probably a Hobby but very quick), some of them returned within a few minutes..
Mon 14th again Chiffchaff singing Longwood on a glorious warm Autumn afternoon (max 26.9c record).
Wed 16th Chiffchaff again Lampeter University close to the Old Building; another singing well late afternoon at the forestry.
Most of the Swallows and Martins departed towards month end with the cool north winds of late..
Sat 26th still perhaps half dozen H Martins Lampeter; forestry - fair second bloom of Foxgloves underway (these may last to November provided no hard frosts); evening half dozen Swallow village
Mon 28th Chiffchaff singing in Carmarthen town centre this morning near the library
