A few individuals of a bird species fly to a small city that previously had no individuals of this species. The immigrant birds find that the city has adequate food and no predators. On average, each bird has four offspring per year and lives for two years. Imagine that after the birds have been living in the city for many years a second big flock of birds arrives. How will the bird population size change in the 10 to 20 years after the extra birds arrive?
