Female, shown foraging in wild orchids
"From Ubin all the way to Ferry point Jeff heard a chain of loud cackle, yak-yak-yak. These feathers appear to omnipresent. A widespread and fairly common resident throughout most of the region. Rare resident in Singapore.
Came as a pair. Female's casque is smaller and darker than the male's. Shown pair in available evening light only."
Thanks to Jeff for kindly allowing me to reproduce his images here. All rights remain his!
