Bachman's Sparrow Ap Bio Lab Answers
General Biology Endangered Animal Species Report Sarah Finnegan
Bachman 's Sparrow
II. Physical Characteristics: Relatively small in size ,plain brown in color with reddish streaks, cone shaped bills, pale brown faces, long brown tails , reddish brown backs, pale white breast , brownish-red crown. Length 12.2 to 15.2 cm Weight 21 grams
III. Food: Forage on the ground for seeds of herbaceous plants and pines, and for insects. Insescts include beetles, bugs, grasshoppers, crickets, millipedes and spiders.
IV. Geographic Distribution: In Southeastern U.S. In few Ozark-area counties in Missouri V. Habitat: Areas with scattered, scrubby vegetation and a dense herbaceous understory. Dry, open pine or oak woods …show more content…
Why is Bachman’s Sparrow considered endangered? Their population has diminished mainly because of the logging of pine forests in the early 1900s. Succession of savannas and glades to dense, woody areas because of fire suppression and invasion by cedars into glades have also drastically reduced available habitat.
VIII,Local Ecosystem: Lke Bachman sparrow, some animals prefer frequently burned areas like gopher tortoises that feed on grasses and herbs in frequently burned areas, and their burrows are often used by Bachman’s Sparrows for escape cover. Bachman sparrow disperses seeds and destroys some insects and other bugs to balance the ecosystem. Their commensal/parasitic species (symbiotic relationship in which one species is benefited while the other is unaffected ) are brown-headed cowbirds
IX Human Impact on Its Diversity and other Species ecologically involved Bachman 's sparrows have no direct effect on humans. They play a key role in the food chain, in that they eat insects and other arthropods and keep their population down. They are not harmful to humans. Human’s logging for development affected their habitat. Their fire protection policy affected prime habitat for Bachman’s Sparrow, red-cockaded woodpecker, and other pine-grassland
