then another will fly a foot or two off the ground and settle 

 again directly. It may be that they are in this way looking 

 out for danger. 



They always perch in very prominent positions on trees 

 and for this reason are difficult to approach. I have heard 

 them utter a very subdued continuous wailing cry.

" Iwabai Tintaba." 



This Crow has been seen flying around the granite kopjes 

 at Hillside. It appears to be confined to the neighbourhood 

 of hills, and more especially those of the granite formations 

 such as we have in the Matopos about 40 miles south of 

 Bulawayo, where I have seen this bird in great numbers. 



162. CORVUS SCAPULATUS. 



Corvus scapula/us Stark, Birds S. Afr. i. p. 12. 



"Iwabai." 



An extremely common bird in the town from January to 

 June, but during the rest of the year only a few are seen 

 occasionally. It frequently rests in trees or on the posts 

 supporting the electric-light wires. Its foods consists of 

 scraps of meat or other offal, and I have also seen it hunting 

 for ticks on donkeys' backs. It has a harsh guttural croak.

1. Allen on Bseolophus bicolor-atricristatus. 



[The Bceolophus bicolor-atricristatus Group. By J. A. Allen. Bull. 

 Am. Mus. N. H. xxiii. p. 467 (1907).] 



The Tufted Titmouse of the Eastern United States 

 (B(Eolophus bicolor) is replaced in Texas and Mexico by the 

 quite distinct species B. atricristatus. The breeding-ranges 

 of these two species, as it has recently been discovered, 

 overlap in Southern and Central Texas, where intermediate 

 forms are found and have been described as new subspecies.
