A Thai Architectural Finial, Thailand

in the form of a stylized chofa bird, the swollen chest beneath a curved tapering neck, the stylized head with pointed bill, surmounted by a tall dramatically rectangular shaped plume; weathered surface with traces of  yellow pigment.

Cf. National Museum Bangkok (1987: 91 with figs. 149-151): "[C]hofa [means] literally 'a bunch of sky' or 'sky tassel.' These finials are found on royal and religious buildings only, and may vary from region to region. They are thought to represent a hamsa or celestial goose that the god Brahma rides, or the garuda, the vehicle of the Hindu god Vishnu".
