of Germany are alfo great numbers, for we are told, that they are: 
found in vaft abundance in the wood ef Rofendabl, near Drefden; in 
which neighbourhood Larks alfo are in fuch amazing quantities, as 
to furnifh a confiderable revenue to the crown +. 
It has not efcaped the writers on this fubjedt, that the males and fe- 
males of fome birds, for inftance, Chajfinches, feparate for a tume into dif- 
ferent flocks, each flock confifting of one fex only; but my ingenious- 
friend Colonel Montagu hints to me, that. the males of all the Yar- 
blers come firft, and if the weather fhould afterwards prove. cold, 
with the wind at Eaft or North, all communication is cut off between 
the {exes till the wind changes, frequently for a fortnight or more; 
but if the weather is warm, with a South or Weft wind, the females 
follow the males in a few days. The arrival of the females may be 
foretold by the fingine of the males: if they are very vociferous,. 
the females may be immediately expected; -if, on the contrary, none- 
will appear, for both are actuated by the fame caufe;. the fame fti-

feek its mate; and from this caufe no doubt it is that moré males of. 
the Nightingale are taken than females.. 5
