Rare below about 6,000 feet, but very common above that 
limit to over 8,000 feet, flying in small flocks of six or seven 
individuals, often in company with Mesta laurimie and 
searching fallen timber for insects, etc. 
There has been much diversity of opinion on the question 
as to whether the birds of this species inhabiting the 
mountains of Sumatra and Borneo are strictly conspecific 
with the continental form from Tenasserim and the moun- 
tains of the Malay Peninsula, which was originally described 
from Mt. Muleyit in Central Tenasserim. 
On comparing eighteen adult males from Sumatra with 
twelve adults from various parts of the Malay Peninsula from 
Bandon to Selangor, it is at once seen that the Sumatran 
birds average very much darker grey than those from the 
mainland and are also distinctly smaller, the bill very decidedly 
so. Salvadori’s original type had no vinaceous tint on the 
flanks but this was not the case in a second specimen from 
Lake Toba, collected by Modigliani. All the present series 
have this tint more or less developed about equally with the 
series from the Malay Peninsula. There is no difference 
whatever in the tint of the upper surface. 
The females from Sumatra, besides the difference in size, 
have the buffy tint of the under surface richer in tone than in 
those from the Malay Peninsula. It is evident, therefore, 
that Salvadori was correct in his view that the Sumatran 
form is distinct from that of the mainland, though we do not 
think that the differences are more than subspecific. The 
bird from Kina Balu is probably identical with the Sumatran 
Tace.
