William Henry Mousley, Which Sex Selects the Nesting Locality (1921)
“ I would suggest they come for the purpose of selecting some area of ground over which they can hold sway, in other words they nominally select the general nesting site, to which the females may come either accidentally, or as is most probably the case (especially with the warblers) , by hearing the males singing from their favourite trees or other posts, which also act as look-out stations, from which they can sally forth and drive all other interlopers away. ”
