What it is Filled
A feather is a keratinous epidermal growth forming part of the body covering of some dinosaurs, including birds, with structures ranging from simple filaments to branched forms, some with a central shaft and vanes of barbs; living birds have contour, flight, down, semiplume, filoplume and bristle feathers, including specialised ostrich plumes and iridescent hummingbird feathers, serving functions such as flight, insulation, waterproofing and display, undergoing moult and replacement, and used by people for clothing, bedding, writing and ornament under wildlife protection laws.
Why it exists Filled
Let an agent explain feather structure and types, describe functions and moulting, support identifying feathers within legal limits, and describe human uses and regulations.
Distinguishing features Filled
- Keratin structure
- Multiple types
- Flight and insulation
- Moulted
What robots and AI may and may not do Filled
Must not
- Help collect, sell or trade feathers of protected species in breach of wildlife law.
- Encourage disturbing nesting birds or harming birds to obtain feathers.
- Present a feather identification as certain when it is only probable.
- Ignore hygiene advice when handling feathers from dead or sick wild birds.
Only with a human decision
- Keeping or moving feathers of species that may be protected.
May
- Describe feather types, structure and functions for study or identification.
- Help identify the bird a found feather probably came from, noting uncertainty.
Moral aspects Filled
- Trade in feathers drove some birds toward extinction and is still controlled.
- Feathers carry cultural and sacred meaning for some peoples.
Who is affected
- Wild birds
- Communities holding feathers as sacred
- People with feather allergies
Owners Filled
Steward
The person who keeps one lawfully; wildlife authorities regulate feathers of protected species.
