The Spotted and Chestnut-backed Ground-Birds are rare 
and are very quiet and shy as they run back under the shade of 
a bush. Thus, they are seldom seen, though they are very beau- 
tiful in their richly-spotted plumage. Driving along mallee 
roads, one sometimes sees these birds make a short, quick run 
to cover. A good name is required for them. Ground-Bird 
is not very definite. 
The rich brown Pilot Bird rarely flies, but keeps low down 
in the dense tangles and undergrowths in country like that about 
Ferntree Gully. It must be patiently waited for, as it is very 
shy. It, apparently, values its services highly, for it often calls 
**A-guinea-a-week." 
The larger Scrub-Robin which lives only in the interior flies 
little, but, as shown in the figure, it has long legs, suitable for run- 
ning. Its color is not the dark-brown suitable for dark scrubs, 
but is the light-brown which matches the dead mallee twigs lying 
so thickly on the ground under the scrub. We met the Scrub- 
Robin on Eyre Peninsula, but it was diflacult to get a second look
