Barrow's Goldeneyes (Bucephala islandica) and Surf Scoters (Melanitta perspicillata) were observed on four separate occasions, by three different observers, foraging on Bay Mussels (Mytilus trossulus) above the water surface. This unique foraging behaviour could be attributed to diurnal spring tides and reduced lower intertidal mussel abundance.

Predator Release

Shortly after the discovery of the introduction of balsam woolly adelgid, Adelges piceae (Ratzeburg), to the south coast of British Columbia, a predator release program was initiated to establish a complex of European and Asian adelgid predators to supplement existing native predators. Between 1960 and 1969, eight species of exotic predators, Aphidoletes thompsoni Mohn (Diptera: Cecidomyiidae), Cremifania nigrocellulata Czerny and Leucopis hennigrata McAlpine [=Leucopis sp. nr. melanopus Tanas. (McAlpine 1978)] (Diptera: Chamaemyiidae), Laricobius erichsonii Rosenhauer (Coleoptera: Derodontidae), Aphidecta obliterata (L.), Scymnus (Pullus) impexus Mulsant, and Scymnus (S.) pumilio (Weise) (Coleoptera: Coccinellidae), and Tetraphleps abdulghani Ghauri (Heteroptera: Anthocoridae), were released (Clark et al. 1971; Schooley et al. 1984).
