I think I read somewhere last year that the first male grasshopper warblers to arrive in these islands are prone to singing from more exposed perches than is their wont later in the season, so it might be easier to get to see one at his time of year. Does anyone know if this is true, and if so, what time in March or April should I begin trying, and what time of morning or evening might be best? I know a few local grobbler sites where I've heard them while out cycling, but I've never seen one except on passage on an island. Any advice gratefully accepted.
