Chick diet in 2015
Productivity in 2015 In 2015 there were 19 focal sites on my St Philip's Stone survey ledge. There were 17 active sites and 2 regular sites. 13 sites produced chicks that either fledged, or were of fledging age (+15days old) when last seen. This gives a productivity of 68%. Of these 13 chicks, at least one failed post fledging.
