8/20/09 - North of Saddle Road, 19 Mile Area (1 Viewer)

I continued exploring the area North of Saddle Road, in the Kaumana Trail area. I was fortunate that the originally forecast rain failed to appear, though the poor forecast prompted me to sleep in an extra few hours.

I started at the 'aiea tree on the main trail, and searched the area between the two big trails. Unfortunately I didn't find any other 'aiea or any other new plants for the area. The area between the trails alternated between mostly undisturbed areas that are too rugged for the pigs, and flat areas that the pigs had torn up badly. There were a few interesting plants, but no rarities or new species for the area. I added a lot of 'anini trees to my map of the 'anini population.

Same birds as usual here. So far these are the frequencies and averages per 8 minute count:


Bird---Kipuka 1-----Kipuka 2-----Big Forest
APAP - 0.82/2.00----0.77/2.54----0.94/2.28
HAAM - 0.91/1.55----0.92/1.54----0.83/1.28
IIWI - 0.18/0.18----0.46/0.77----0.94/1.06
OMAO - 1.00/2.64----1.00/3.69----0.94/2.72
ELEP - 0.09/0.09----0.77/1.54----0.78/1.39
JAWE - 0.82/1.45----0.77/1.31----0.72/1.39
RBLE - 0.09/0.09----0.77/1.54----0.56/1.22
YFCA - 0.36/1.18----0.00/0.00----0.00/0.00

Some things to note about distributions and numbers:

The first kipuka is the smallest forest and has a much less rich flora and more understory disturbance and scrub/bog habitat than the other two areas, so 'oma'o and i'iwi are fewer. However it is more abundant in species that like lava fields and scrub/edge habitats such as canary and 'amakihi. (The canaries are particular to the nearby powerline area of the lava field for some reason - perhaps due to the alien weeds growing along the disturbed bulldozed access trails.)

The second kipuka has the richest and least disturbed understory, and is most abundant in understory birds such as leiothrix, 'oma'o and 'elepaio.

The main forest attracts a bit more of the red canopy-loving birds.

White-eyes can be found anywhere.

'Amakihi avoid large solid canopy wet forests. (not really pronounced here, but they really are absent from many of the larger rainforest areas.)
