172. ZOSTEROPS rather definitely mimicked Myiagra and Aplonis. Gerygone mimicked (and most of the calls very well), Myzomela, Zosterops, Aplonis, Pachycephala, Lalage, Myiagra and Nymphicus very well, but softly, Lichmera, Hypotaenidia and Halcyon somewhat like them. LALAGE mimicked Lichmera very well, but appeared to try others and mixed them up badly. COLUMBA It is also of interest to note the similarity in names for this species on all three islands, possibly pointing to a comparatively recent arrival or a spread from island to island in recent times. WIND AND COLD ACTIVITIES:- It was very noticeable on mornings after a boisterous windy night, even without rain, that the next morning dawn chorus was not as long as usual and birds appeared to quickly settle down ap- parently not feeding for as long as usual irrespective of the weather being cold or hot. Observer noting the species most affected concluded that those species which perched well out in the outer smaller twigs of trees and fairly high up and in rather open situations subject to wind movement had experienced such a physical strain keeping their perch and balance that they were tired out and after a little feeding and satisfying of their first hunger quickly retried to sheltered positions to obtain some rest. The rule seemed to hold good over all species, high and wide perchers like Myzomela retiring earliest,
