Results

•• Population increasing rapidly Population increasing rapidly (~13% annually)(~13% annually)

•• CMR analysis of 10 yrs PIT CMR analysis of 10 yrs PIT tag data yield high nesting tag data yield high nesting female survival probabilities female survival probabilities (~90%). (~90%).

Nest Relocation30 – 40% of nests are relocated to stable beach areas

Research Projects• Nest excavation and hatch

success analysis

• Analysis of effects of temperature, moisture, vegetation on nest success

• Blood sampling to determine population structure, age dynamics, nesting physiology, and metabolism

• Satellite telemetry to determine migration, diving, and movement patterns of nesting females

Conclusions

• Beach protection and egg relocation can be effective management tools . . . . Long term recovery efforts on Sandy Point appear to have paid off!

• Need high adult survivorship for continued recovery. . . . We estimate annual nester survival of this population to be about 89%, which is consistent with a healthy population!
