3.3.3 Adult and juvenile survival and re-sighting rates Nearly half of the adults banded in 2006 were not seen in 2007 (Fig. 3.12). However, more than two-thirds of all the adult birds banded in 2007 were re-sighted in 2008 and 2009. In 2010, the resightings of birds banded between 2006 and 2008 were at or less than 20%. The re-sighting rate of adults banded in 2009 seemed high in 2010, but it was only because two out of three banded adults were sighted. Proportion (%) of individuals re-sighted Figure 3.12 Proportion of adult birds banded each year that were-sighted in subsequent years Only 8.7% and 13.0% of juveniles banded in 2007 were re-sighted in 2008 and 2009 as yearlings and adults respectively, whereas 38.2% of 2008 juveniles were re-sighted in 2009 as yearlings. The re-sightings of juveniles hatched between 2007 and 2009 was at or nearly zero in 2010 (Fig. 3.13). 90 80 70 60 50 40 30 20 10 0 Banded in 2006 Banded in 2007 Banded in 2008 Banded in 2009 48 2007 2008 2009 2010

Results from the two best-fitting averaged models (Tables 3.9 & 3.10) suggests that survival for adults varied through time but survival of juveniles stayed constant throughout the years 2006- 2010 (Fig. 3.14). Adult survival almost reached 100% in 2008-2009, but then crashed to 15.14% in the years 2009-2010. Although survival rates of juveniles to their first years were slightly higher than survival rates adults, differences in survival rates between them were not significant between 2006 and 2010 as the 95% CI for both categories overlap for those years. Re-sighting rates of adult and juvenile C. cyanus were constant throughout 2006-2010 (Fig. 3.15). Re-sighting rates of juveniles were only slightly higher than adults (Resightings, p: Juvenile = 65.72%, SE = 0.110; adult = 57.29%, SE = 0.091). Table 3.9 Models that had a Delta QAICc of 2 or less.
