Snares Penguin egg survivalThese data describe the fate of Snares penguin A-eggs and B-eggs in 50 nests during the 2002 breeding season. The file has the following columns: Date (date of observation): all nests were observed for 4 hours each day to determine the status of all eggs in nests and to observe aggressive events; Nest id (identification number of each nest); A alive? (the A-egg is alive and being incubated = 1; A-egg lost or hatched = 0; A fate (A-egg fate): it explains what happened to each egg; B alive? (the B-egg is alive and being incubated = 1; B-egg lost or hatched = 0; B fate (B-egg fate): it explains what happened to each egg; F present (the female is present at the nest on this date = 1; the female is not present = 0); M present (the male is present at the nest on this date = 1; the male is not present = 0); Inc shift (incubation shift during the course of incubation); day shift (which day in the incubation shift); No of attacks (Number of aggressive attacks on this nest on this date); Total min (total minutes of all attacks on this nest on this date); Mean dur (mean duration of attacks on this nest on this date).
