THE YELLOW-BREASTED CHAT. 185 
or marshy weed-lots, or over-grown fences running through lowland meadows, 
there are they. The male spends much time singing, seeking for the purpose 
the summit of a weed-stalk or a flowering shrub, or occasionally mounting a 
sapling twenty or thirty feet high. Witchity, wichity, wichity, or “I beseech 
you, I beseech you, I beseech you”, sounds forth at intervals in sharp anatriptic 
notes which pierce the morning chorus for a hundred yards. 
Meanwhile the plainly attired but dainty female is weaving a bulky nest 
in some weed-clump or grass-tussock hard by. Sometimes it is sunlx in the 
center of a tussock almost to the level of the ground. At others it is lodged 
in the spreading branches of a bush, or else the crowded heads of certain 
plants are brought together and made both to support and shelter the tightly- 
woven structure. The nest is a model of strength, and notwithstanding its 
usual bulkiness, is well moulded and neatly lined within. According to Dr. 
Jones the male bird assists somewhat in the construction of the nest, and 
both birds watch over it with jealous care. ‘wo broods are commonly 
reared during the season, one in May and another in July. When the nest 
is threatened, or indeed at any time when intruders are about, the birds give 
frequent voice to a most peculiar and distinctive note, a sort of Polish conso- 
nantal explosion, wzschthwb—a sound not unlike that made by a guitar string 
when it is struck above the stop.
