immediately started his tinkling little note to be answered 
by several other birds in trees close by. On our return 
some hours later two of these little red-headed birds were 
discovered at this same waterhole. The bird most in

pairs of which bird were scattered through the bush as 
we passed.

over just as carefully, still cracking in a most laughable 
wav on the top note. The field glasses showed us a butcher 
bird as the second minstrel. Evidently the thrush was 
giving a singing lesson, but try as he might the butcher 
bird could not get that top note, though he managed the 
rest of the song splendidly. Both birds were very much
