were near groups of nesting silver gulls Larus novaehollandiae (Sagar 1978; Higgins & Davies 1996; Garnett & Crowley 2000; Miskelly et al. 2001). Dispersion Often gregarious, forming flocks after breeding and in the non-breeding season. Breeding may be solitary or colonial. Detectability Conspicuous at sea and on land, particularly when in flocks. Recommended methods At sea, shipboard surveys. For inshore waters, boat transects and observation from onshore vantage points using telescopes. On land, area searches or transect surveys. Detection of flying birds, and nests. Scanning through mixed flocks of roosting or foraging terns is a potentially useful method of detection. Surveys of beach cast birds may provide an opportunity to detect this species, though they provide little information on origins of specimens as bodies are usually displaced by currents and winds. Colony sites are well documented, with the only Australian breeding occurring at (Higgins & Davies 1996).
