and with distended air-sacs almost hiding the head, outspread 

 tail, and trailing wings, they strut slowly about before the 

 females, uttering meanwhile low gutteral sounds. The males 

 do not take any part in the incubation, and remain apart till 

 the young are grown. In autumn the birds pack, and may 

 then be seen in large numbers.
