His findings confirm my feeling that territories are very large, exceeding 750 m in their longest dimension. He felt that several pairs of T lacked mates even though they were defending territories. One of these cases was disproven, however, when McCaffrey found the nest with one egg. The records of jaegers (observed on Grid 3 egg 8 days ago (up to 7 perched on a single HCP, all fighting over one hatching) has disappeared. SEXING JAEGER: according to FAT TOT have longer central retrices, a cleaner vent, and whiter breast: In general if you can look at both members of the pair, scoring is no problem 20 June Pitka observed today that there are many unsettled pomarine soaring through, something not ordinary
