The red-billed starling, “silky starling”

Description

21–24 cm; 65 g. Medium-sized starling with forehead, crown and nape feathers somewhat elongate and hackle-like.

The red-billed starling (Spodiopsar sericeus) also called “silky starling” is found in China, Japan, South Korea, Hong Kong, the Philippines, Vietnam and Taiwan.

In Hong Kong, the red-billed starling is an abundant winter visitor to open habitat. Small numbers stay in summer to breed. In winter, the red-billed starling forms large flocks.

Fun fact about the red billed starling 

Little is known about the surprising breeding ecology of the silky starling. A study conducted in 2011 with artificial nest boxes to study the breeding ecology of red-billed starlings and white cheeked starlings showed intraspecific nest parasitism (INP) behaviours by the red-billed starlings. Using the obvious morphological differences or partition of egg-laying on 40 nest boxes installed, the study showed:

  • 33 boxes were occupied by the red-billed starlings
  • 17 brooks were successfully hatched
  • The clutch size of red-billed starlings starlings ranged from 6 to 7 eggs
  • The clutch size of white-cheeked starlings starlings were above 7 eggs
  • Red-billed starlings had a longer nestling period than white-cheeked starlings, as well as a higher feeding rate
  • Red-billed starlings were more vigilant and more agressive that the white-cheeked starlings during their nestling period.

One of the nests was later confirmed INP by the red-billed Starling, after the fledglings had fledged.
