the inner webs: “bill deep bright chrome-yellow ; tarsi and feet chrome; iris pale ash-colour,

Adult female. Similar to the male in colour. Total length 9 inches, culmen 1:0, wing. 4:8,

Immature birds have triangular spots of orange-buff at the end of the median and greater 
coverts, while the underparts are paler than those of the adult and are mottled with broad blackish 
tips to the feathers. They differ from the nestlings of 7. olivaceus in having a grey shade over the 
throat and chest, the latter being slightly mottled with blackish ends to the feathers. 
The descriptions are taken from Transvaal specimens, and the one figured in the Plate is in the 
Shelley Collection, and is said to have been procured in the Cape Colony by Mr. Butler.
