The Type 1 survival curve indicates that this species has a high survival rate in the early stages of life, which allows for a delayed reproduction strategy. Older female birds producing more eggs suggests a slow maturity rate, allowing for greater investment in each breeding attempt. This combination of delayed reproduction and slow maturity is a common evolutionary strategy for long-lived species with low mortality rates early in life, such as sea birds.
