St. Agnes Bird Observatory (Plate 5 9) O N T H E M O R N I N G of 30th September 1958, G.J.H. and R.E.S. discovered at Govean, on the eastern side of St. Agnes, Isles of Stilly, a small ground-feeding bird which they identified as a Northern Waterthrush {Seiurus noveboracensis).

After examination at the observatory it was photographed in colour and then returned to Covean and released. It remained there until 12th October and during its stay was seen by several other observers including J.L.F.P., R. E. Emmett, B. S. Milne, P. Z. Mackenzie and R. Symons.

In the field the first impression was of a small, plump, pipit-like bird, dark olive-brown above with a well-marked yellowish-buff superciliary stripe and yellowish below with heavy, dark brown streaks. In size it was noticeably smaller than Rock Pipits {Anthus spinoletta) near-by and its plump appearance was very marked, more so than in the illustration in Peterson (1947). For most of its stay it tended to frequent one corner of a small cove, where rotting seaweed had been piled up at the foot of a tamarisk hedge, but latterly, when the weed had been washed away by high tides,
