Hegura I. is a small flat island with almost no tree, situated 27.5 miles from the tip of Noto Peninsula. Very few birds have hitherto been recorded. The author received lighthouse-struck birds four times in May and June, 1961 and 1962 These are, <i>Turdus sibiricus, Larvivora cyane, Motacilla cinerea, Muscicapa alseonax, Mnscicapa griseisticta, Muscicapa narcissina, Locustella fasciolata, Locustella lanceolata, Locustella ochotensis, Phylloscopus borealis</i> and <i>Acrocephalus bistrigiceps, Lobipes lobatus</i>.<br>These records support author's previous view that passerine migrants migrateoffshore rather than close to it and the lighthouse may often benifit them for temporal landing in cloudy and bad weathers (all above birds were obtained in such conditions), though small part of it may die by striking at it.
