The effects of disturbance to off Vancouver Island, Canada were quantified by testing distances roosting or nesting birds showed an agitation response approaching motorboat kayak. species sensitivity, vessel type, habituation season on distance examined. At 40 m from boats, Double-crested (Phalacrocorax auritus) Pelagic (P. pelagicus) cormorants, Black Oystercatchers (Haematopus bachmani), Glaucous-winged Gulls (Larus glaucescens), Pigeon Guillemots (Cepphus columba) had less than 6% probability being agitated with either kayak motorboat, while at 50 was 2% agitation. Roosting larger birds. Harlequin Ducks (Histrionicus histrionicus) particularly sensitive ...
