• St Philip's Stone 2014
• Feeding-trip duration in 2014 31 timed feeds out of 77 (40.26%). Mean duration of timed feeds = 32m55s, median duration = 23m10s.
• Parental attendance in 2014 Mean time that both parents were at nest site was 20.17% (=46h47m21s/232h00m00s).
• Chick diet in 2014
• Productivity in 2014 In 2014 there were 16 focal sites on my St Philip's Stone survey ledge. Site H was unoccupied this year, perhaps due to the severe storms of winter 2013-14. There were 15 active sites and one regular site. 12 sites produced chicks that either fledged, or were of fledging age (+15days old) when last seen. This gives a productivity of 75%. Of these 12 chicks, at least one failed post fledging.
