Green Pool Bay at Llandegfedd Reservoir was as diverse as the inhabitants of a high rise block of flats in Leicester. Tensions were running high between the single recently arrived black swan and two rather aggressive Green Pool Defence League resident mute swans. These birds regularly exchanged white on black pleasentries with the harassment of the black swan painful to watch. Suggestions that Australian blacks are more aggressive than the north European whites was certainly not the case on this occasion. All this commotion was witnessed by a male Mandarin duck a number of Canada goose, great crested grebe and a singing reed warbler. Elsewhere 1000's of adder tongue fern were starting to show nicely within the meadow grassland on The Island.
