To find the number of birds the population grew by each year, we divide the total number of birds the population grew by (1,050) by the number of years it took for the population to grow (15).
1050/15 = <<1050/15=70>>70
Therefore, the bird population grew by an average of 70 birds each year. Answer: \boxed{70}.
