Using xhe formula, the number of acres in Nihon divided by the acres sampled 
would give us a conversion factor and this came out to 32 #9* number Oi

method seems to be the best method of estimating these birds. Considering 
that we calculated a population of 4,770, rounding it off a population of 
5 000 is not unreasonable# Millerbird data was computed the same way# 
A total of 19 birds were seen, 12 of these were in the west one-half transect,

625 . Millersirds in the east one-half transect were found at all elevations 
and Just about in all types of vegetation# We found them at elevatxons of 
150’ and clear on up almost to the top of Tananger Peak. Of the 8 sirds 
by Xridler and Sincock, 3 were seen on the east ridge (the bottom) Just
