dickcissel การใช้

• Even the rare dickcissel has been sighted at Big Summit Prairie.
• The dickcissel, a species of bird endangered in Illinois, has settled there.
• Dickcissel populations frequently fluctuate in numbers, even to the extent that their range changes notably.
• In the Spring, this park serves as an abundant wildflower locale, as well as a birding resource, with nesting pairs of meadowlark and dickcissel.
• If that is correct, the dickcissel in the genus " Spiza " would, quite amusingly, indeed turn out to be one of their closest living relatives.
• It is commonly called " Townsend's dickcissel " ( or " Townsend's bunting ", " Townsend's finch " ) in reference to the collector whom the scientific name honors.
• Some of these include the fulvous whistling duck, black-bellied whistling duck, white-tailed hawk, northern caracara, scissor-tailed flycatcher, dickcissel, roseate spoonbill, anhinga, Sprague's pipit and sandhill crane.
• Birds in the Osage Plains include the threatened greater prairie-chicken, Henslow's sparrow, dickcissel, loggerhead shrike, field sparrow, scissor-tailed flycatcher, Bell's vireo, painted bunting and Harris's sparrow.
• Though the color pattern and habits of the dickcissel make it stand apart from other Cardinalidae, its robust cone-shaped bill  stouter than in American sparrows or true finches which it somewhat resembles at first glance  gives away its relationships.
• No specific details are known about the dickcissel's lipochrome metabolism; it may be that it happens to be more fine-tuned than in other birds, so that most mutations therein will be lethal and Audubon's bird was simply one of the very few individuals that survived.
• It stands to note that in wild birds, varying from species to species some color aberrations are less frequently seen than others, and that in captive birds such as molecular biological study of the dickcissel's metabolism and the specimen's ancient DNA stands any reasonable chance to resolve the question with certainty, the hypothesis of an extremely uncommon color mutation is plausible, and such phenomena certainly occur in other Passeroidea.
