Every year, the Royal Society for the Protection of Birds (RSPB) asks people to do a survey of the birds seen in their gardens. In 2011, over half a million people took part and you see some of the results the RSPB received in the two tables below:



The first column of both tables shows the names of the birds.  The second column of the left-hand table shows the average numbers of those birds across all the gardens. The second column of the right-hand table shows the percentage of all the gardens in which those birds were identified. 

You may need to have a chat with others to get a clear picture of the meanings of "average per garden' and "percentage of gardens with the bird".

Have a general look at both tables. What can you say about them?

What can you can about the ranking of the starling?

What can you say about the ranking of the robin?
