      (72 feeds / 218 chick.hours = 1.32 feeds per chick per 4 hours).
    • Parental attendance Mean time that both parents were at nest site was 12.29% (=27h02m00s/220h00m00s).
    • Feeding-trip duration 20 timed feeds out of 79 (25%). Mean duration of timed feeds = 44m50s, median duration = 33m54s.
    • 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.
