summary of 2010 bird nestbox surveys

 Here is a rather complicated spreadsheet of the nestboxes.

First there is a summary of the number of successes and failures
Then a sheet including all the information by nest box, listing the detail in time order
and then the three sheets of the separate surveys

23 out of the 65 boxes remained empty
34 were successful
8 were failures in either abandoning eggs or failing to complete a nest

because of the poor weather conditions, too wet or too hot there was a big gap which sometimes meant that the species was not determined
