In the years 1992/1998, in Busselton, W Australia, nesting of two species of cormorant, Phalacrocorax melanoleucos and P. sulcirostris, always took place in close proximity to inhabited nests of Anhinga novaehollandiae. Evidently, nests of the latter strongly attracted cormorants about to start nesting. Although this attraction had been noted before (Vestjens, 1975), strangely, it was ignored in later standard works.
