The habits of this bird are very different to those of the other 
members of this family, and one would scarcely know it to belong 
to the Robins. It pipes its Moe notes from early to late, and 
when other Robins are in the shade, this is most actively chasing 
and eapturing grasshoppers. E^ freely associates with other 
birds (as the Artamide). Amongst birds in general, there 
appears to be security in numbers.

mage of what are called the Red Robins is quite im- 
perfect * the close of 12 months, yet in this phase they nest and 
rear a family. Immature birds in Victoria have nested in 
August of different years. Matured birds will breed twice in a 
season with two to three eggs laid on successive days. Incubation 
lasts 14 days, Ae which the disturbed bird will often feign 
injury when you approach the nest. Mr. J. A. Hill, of Kewell, 
in a letter to me gives the time between the starting of nest- 
eds; one patch of brownish feathers remain iet on the chest, 
while all the others either had * burst their buds " or were doing 
So into bright-red. Excepting the middle feathers, all the others 
of the tail were short and irregularly graduated. The brownish
