about daybreak singing on some high reed or braneh of a tree. Tiie topmost spray of a bush or the su mmi t 
of a tall reed is their favourite perch throughout the fen or broad-district. In the south I have watched 
them on two or three occasions at an elevation of from twelve or fifteen up to even twenty feet in the branches 
of an oak. If undisturbed during fine still weather, the monotonous note is frequently continued with but 
slight intermission for the first two or three hours after daybreak. The slightest sign of danger is sufficient 
to cause them to drojD like a stone into the thick cover, whore they quietly remain creeping about like 
a mouse till the place is again quiet.
