A day spent guiding some visitors around tourist sites in the central belt provided some useful opportunities to gather breeding evidence for several species. The Falkirk Wheel held House Martins visiting likely roof overhangs and a Swallow mobbing some Rooks that came too close to its presumed nest. A Yellowhammer was singing at The Kelpies. A Swallow seen commuting through the open door of Linlithgow Palace presumably had a nest inside. At least seven occupied Fulmar nests were on the cliffs below St Andrews Cathedral, while in the Cathedral grounds, a pair of Oystercatchers had two large young and a pair of Herring Gulls had one. In St Andrews harbour, a female Mallard was escorting seven newly-hatched young and fending off the attentions of a Carrion Crow and two Grey Herons. Nearby, a Swallow was flying into the gents toilets to feed four juveniles lined up along the top of a cubicle door frame. Finally, two newly-hatched Eider ducklings were with two adults in Crail harbour.
