on 22nd April 2022

Post 1.

An Oriental Honey Buzzard (Indomayalan HB, Crested HB), Pernis ptilorhynchus torquatus, in the uncommon tweeddale morph resembling a Blyth’s Hawk Eagle plumage with a prominent crest (avian mimicry). Both males and females in this morph have yellow-orange eyes and dark heads. The P. p. torquatus are resident in Peninsular Malaysia. Post 1 above shows the bird collecting nesting material from a Pterocarpus indicus (Angsana tree).

Post 2 above, flying with a branch from a Samanea saman (Rain Tree). Both collections I observed were small branches with fresh foliage, broken using the beak and transported in the claws. The partner, looked like a possible male, had yellow-orange eyes but lighter plumage – the commonly encountered ‘intermediate morph’, to use terminology in the recently published ‘Chong Leong Puan, G. W. H. Davison, Kim Chye Lim (2020). Birds of Malaysia: Covering Peninsular Malaysia, Malaysian Borneo and Singapore. Lynx Edicions’.
