More on Straw necked Ibis. At Thredbo on
Monday evening a flock of 200 to 300. Also I can report a lot of dependant
young Little Ravens, most pairs of adults had 2 young. The species was
hardly out of sight from the top of the chair lift to the roof of our fair
land. Also saw 4 Aust Kestrals just below the summit.
Question unrelated to birds. When leaving
Rawson's Pass on the return journey to Thredbo, there are animal tracks under
the raised grated walkway. These take the form of "runways" through the
vegetation and can be followed for up to 20m or more. This activity is
evident for maybe 500 to 800m. What animal is responsible? It
strikes me that the grate provides excellent protection from winged
predators.
