The presumed intergrade flava x thunbergi was again present on our lawn and was briefly joined in flight by a second individual. I managed a few sound-recordings of the intergrade calling. There was unfortunately no sign of the Bluethroat or Subalpine Warbler.
Norwick: Kestrel, 3 Collared Dove, 2 Swallows, 2 flava Wagtails, Common Whitethroat, singing Willow Warbler & 2 Tree Sparrows.
