3. A population of 1,492 Baltimore Orioles is introduced to an area of Nerstrand woods. Over the next year, the Orioles show a death rate of 0.395 while the population drops to 1,134. What’s the birth rate for this population? Is this proving to be a suitable habitat?

**3. A population of 1,492 Baltimore Orioles**
A population of 1,492 Baltimore Orioles is introduced to an area of Nerstrand woods. Over the next year, the Orioles show a death rate of 0.395 while the population drops to 1,134. What’s the birth rate for this population? Is this proving to be a suitable habitat?
**4. Turkey Population Dynamics in Merriam Township**
780 turkeys live in Merriam township, which is 92 acres in size. The birth rate is 0.472 turkeys/year. The death rate is 0.331 turkeys/year.
a. **What is the population density?**
b. **What is dN/dt?**
c. **Predict N after one year, assuming dN/dt stays constant.**
**5. Dandelion Population Growth**
One dandelion plant can produce many seeds, leading to a high growth rate for dandelion populations. If a population of dandelions is currently 40 individuals, and r_max = 80 dandelions/month, predict dN/dt if these dandelions would grow exponentially.
**6. Logistic Growth in Dandelions**
Imagine the dandelions mentioned in #5 cannot grow exponentially, due to lack of space. The carrying capacity for their patch of lawn is 70 dandelions. What is their dN/dt in this logistic growth situation?
