There is a paper somewhere (Emu??) that describes the foraging niches of 
the Golden Whistler.  Yes, the male does forage, on average, higher than 
the female.  I'm sure someone out there will come up with the precise 
reference.

In regards the "shyness" of the male.  It is also possible that there are 
simply many more female plumaged birds out there than coloured males. 
Males do not attain the gold plumage until at least their third year so 
there will always be more female like birds in the population.  It is also 
possible that not all full plumaged male birds migrate, or at least not as 
far as brown birds.  This would further increase the ration of brown to 
gold birds in a wintering area.

Cheers
