About 80 YFHEs passed through
Robertson at noon today, heading in their normal (for this area) direction of
NE. That would take them to the Illawarra Plateau (Woronora Plateau - southern
end), at its closest point to Robertson.
These birds came up out of the
Sandstone plateau near Belmore Falls (above Kangaroo Valley). They were
crossing over the Robertson Basalt hills, and keeping on going, as there is
little of their favourite nectar-producing food sources growing on the
basalt.
Interestingly, the conditions
were fully overcast at the time of the movement. From my memory from days spent
at Pine Island, and Point Hut Crossing, observing the birds moving through
there, they would not normally move when the sky was overcast. Today these birds
were doing that.
This was the largest group I have
seen this year.
