The Ruby Throated Hummingbird has a resting heart rate of 250 beats per minute. When it is threatened or chased, it's heart rate can reach 1200 beats per minute. Predict its lifespan and justify your explanation.
There are many animal species that seem to have an average life span of about 1 billion heartbeats. Birds and humans included.
See

for more about that.
Hummingbirds don't spend a lot of time resting. I'd expect an average heart rate of 500 b.p.m. At that rate, one billion beats would take 4 years.
That happens to be the observed average life of that bird species. Some have lived 12 years.
To predict the lifespan of a Ruby Throated Hummingbird based on its heart rate, we need to consider a few factors. While heart rate is an important aspect, it is not the sole determinant of lifespan for any organism. Other factors like environmental conditions, predators, availability of food, and diseases also play significant roles.
To estimate the lifespan of a Ruby Throated Hummingbird, we need more data points than just its heart rate. Unfortunately, heart rate alone is insufficient for such a prediction. Lifespan is influenced by various factors, including genetics, reproductive success, habitat quality, and availability of resources like food and nesting sites.
To get a more accurate estimate of a Ruby Throated Hummingbird's lifespan, we would need to consider studies or research specifically focused on this bird species. These studies often involve capturing a sample of individuals, marking them, and monitoring their behavior and survival over a long period of time. Scientists also use demographic data, such as breeding success and survivorship, to estimate lifespan.
Given the limited information available on heart rate alone, it is not possible to accurately predict the specific lifespan of a Ruby Throated Hummingbird. However, hummingbirds, in general, have relatively short lifespans compared to larger bird species. The average lifespan for hummingbirds ranges from 3 to 5 years, with some individuals living slightly longer. But again, this estimate may vary depending on various factors.
To obtain a more accurate prediction, I recommend referring to scientific studies or consulting experts in ornithology who have conducted specific research on the Ruby Throated Hummingbird.
