It was decided that for both the Miller bird and the Finch it would be 
far more reliable because of the secretive habits of the Miller bird as 
veil as the thickness of, the vegetation in certain areas which would

0j .- 6 ! on each side of the group. One man observing, the other man helping 
observe and recording also. One half mile of transect would equal one acre. 
Uihoa is calculated to be about 156 acres. A total of 12500 square feet 
was included in the transect which would equal about 4.735 acres sampled. 
Using ohe formula, the number of acres in jtfihoa divided by the acres sampled

would give us a conversion factor and this came out to 32 . 9 * Ihe number of 
finches observed in the sample which was l45 x the factor which was 32.9 
gives us an estimated population of 4,770. A few finch might have had their 
nesus in some of the-very thick vegetation, but by and large the 1 ’rod -.wide; transect 
meclod seems to be the best method of estimating these birds; Considering 
we calculated a population of 4,770, rounding it off a population of 
is not unreasonable. Millerbird data was computed the same way. Vv '2‘
