To find the total population of birds in the country, you need to add the populations of the two islands together:

1. The population of birds on the first island is 1.105 million.
2. The population of birds on the second island is 2.21 million, which can also be expressed as 2.210 million (by adding zeros for consistency in the decimal format).
