An ornithologist compares two birds: Bird A migrates 1,200 km in 10 days, while Bird B migrates 1,500 km in 15 days. What is the difference in average daily distance between the two birds?

**An ornithologist compares two birds: Bird A migrates 1,200 km in 10 days, while Bird B migrates 1,500 km in 15 days. What is the difference in average daily distance between the two birds?** In a world where migration patterns spark curiosity, one unassuming question reveals a quiet truth: how does endurance and pace vary across similar journeys? Scientists observing bird migration often compare specific routes and timeframes to better understand energy use, environmental navigation, and survival strategies. Recent discussions among researchers dive into a classic comparison—Bird A covers 1,200 kilometers in just 10 days, while Bird B travels 1,500 kilometers over 15 days. This raises a clear, measurable question: what is the difference in average daily distance between these two birds? Breaking down the math, Bird A averages 120 kilometers per day (1,200 ÷ 10), whereas Bird B averages 100 kilometers per day (1,500 ÷ 15). The difference in average daily distance is 20 kilometers—Bird A travels 20 km more each day on average, completing its journey faster through greater daily output. This apparent advantage reflects more than just speed; it signals differing strategies in migration. Birds may optimize flight paths, rest periods, and energy expenditure, leading to variations in daily average distances. Understanding these differences helps ornithologists inform broader ecological insights, such as how climate shifts influence migration routes and how species adapt over time.
