FINAL CONCLUDING PARAGRAPH: In conclusion, birds with larger wingspans have a larger body mass and higher metabolic rates than birds with smaller wingspans. With the limited data provided by the Quaardvark database, further analysis should be done for this comparison by obtaining similar data from other researchers on this topic. In addition, other factors including body temperature, environment where organism lives, body surface area, rate of wing flapping, soaring, gliding, migratory patterns, and so on should be included to provide a more accurate picture of wingspan and metabolic rate comparisons.
