Definition: Yellowthroats are a type of bird in the family Turdidae, known for their distinctive yellow coloring, which typically appears on their bills, wings, and sometimes the upperparts. They have white underparts, and they can be found in many parts of the world, including North America, Australia, New Zealand, Europe, and Asia. The term "yellowthroat" was coined by English author J.R. R. Tolkien to describe a species of bird that lived near Mount Kilimanjaro, which is known for its yellowish or brownish coloration. However, it has since been used more broadly to refer to any type of bird with a distinctive yellow coloring. The definition of "yellowthroat" can vary depending on the context and usage, but generally includes a variety of birds that have a yellow-colored plumage or have yellowish-brown feathers. They are often found in forests, grasslands, deserts, and other areas with high levels of sunlight and light shade, as well as in humid areas where temperatures reach above 25Β°C. Yellowthroats can be found in several species, including the Yellowthroat (Cygnus cygnus), which is known for its yellowish-brown coloration. They are also found in many other species that have a similar appearance or characteristic traits, such as the Lesser Yellowthroat (Cyanthus minor), the Red-breasted Warbler (Thylacoleo tricola), and several other species of birds with yellow-colored plumage. Yellowthroats can be observed during the breeding season from May to September in many parts of the world, where they are found in mixed populations of other bird species. They are also active in areas where there is low light or shade, such as rocky habitats or grasslands.
