Grasshopper Warblers - Teifi Marshes

Three / four Grasshopper Warblers singing this morning, one with a slightly aberrant song, more on this later. Otherwise warblers were quieter than of late.

More on this Grasshopper Warbler
 .... A repeated call like a Corn Bunting from low in the reeds on the Teifi Marsh needed further investigation. A search of  Xenocanto found this call @xenocanto  which points to an aberrant call of a Grasshopper Warbler, with these notes..
 "Aberrant song, apparently most often rendered in autumn. Somewhat reminiscent of song of Corn Bunting "
