Holtz, Thomas (19 October 2018). " "Integumentary Status: It's Complicated': Phylogenetic, Sedimentary, and Biological Impediments to Resolving the Ancestral Integument of Mesozoic Dinosauria" (PDF). Society of Vertebrate Paleontology . Retrieved 16 July 2022. Grebes are peculiar in their habit of ingesting their own feathers and feeding them to their young. Observations on their diet of fish and the frequency of feather eating suggest that ingesting feathers, particularly down from their flanks, aids in forming easily ejectable pellets. [28] Distribution Feather tracts or pterylae and their naming Eagle feathers have great cultural and spiritual value to American Indians in the US and First Nations peoples in Canada as religious objects. In the United States, the religious use of eagle and hawk feathers is governed by the eagle feather law, a federal law limiting the possession of eagle feathers to certified and enrolled members of federally recognized Native American tribes. Because of feathers being an integral part of quills, which were early pens used for writing, the word pen itself is derived from the Latin penna, meaning feather. [10] The French word plume can mean feather, quill, or pen.

PMID 19431311.Celtic feather symbolism is different than what you might find in any other culture because this group of people often saw birds as messengers from the gods above which meant they were always trying to decipher whether or not their presence was good or bad news depending on who it came for. For example, an owl could come before someone died while a bird that looked like an eagle may show up after a new life began and some even believed crows carried souls into the afterlife!

DeMeo, Antonia M. Access to Eagles and Eagle Parts: Environmental Protection v. Native American Free Exercise of Religion (1995) However, Foth (2011) showed that some of these purported stages (stages 2 and 5 in particular) are likely simply artifacts of preservation caused by the way fossil feathers are crushed and the feather remains or imprints are preserved. Foth re-interpreted stage 2 feathers as crushed or misidentified feathers of at least stage 3, and stage 5 feathers as crushed stage 6 feathers. [111] Grande, J. M.; Negro, J. J.; Torres, M. J.

The feather is a recurring motif in many cultures around the world including Native American tribes like the Hopi who believe that feathers represent their link between heaven and earth; for some Pacific Islanders, they represent rainbows connecting the sky-world with our Earth-world; while others attribute them as symbols of love, peace or hope. The spiritual significance of bird feathers may vary depending on what culture you look at if birds are common around your home, think about whether their presence means death or creativity instead; this will help determine what type of feather totem best represents your personality.
