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.

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.

“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' 7 backs. It has a harsh guttural croak.

[The Baolophus bicolor-atricristatus Group. By J. A. Allen. Bull. 
Am. Mus. N. H. xxiii. p. 467 (1907).] 
The Tufted Titmouse of the Eastern United States 
(Baeolophus 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.
