How did nests fare?

Recently fledged Blue Tit by Jill Pakenham

Online participants were also asked to enter an outcome code for each nest that they recorded. From these results it appears that most nests of common species fledged successfully (although this result may be biased, as it seems likely that people were more likely to record successfully fledged young than those where outcomes were unknown or unsuccessful).

For example, in Blue Tit nests where an outcome was recorded, 71% nests fledged successfully, only 2% were predated and 10% failed for unknown reasons (the outcome was unknown for the other 16%).
