DOC rangers weighing an albatross chick

Introduction

See a graph showing the average weight for both male and female albatross chicks.

We use DNA testing to determine the sex of the chicks. Size, weight and temperament of the chick can be used at around 80 days of age as male chicks usually become heavier and larger than female chicks at that stage.

The following graph below shows the average weight for both male and female albatross chicks compared with the 2020 Royal Cam chick Atawhai, and the 2021 chick. The graph also compares the 2019 Royal Cam chick Karere, as she is a sibling of the 2021 chick.

The following graph below shows the average weight of male and female chicks compared with the weight of previous Royal Cam chicks:

  • Karere (2018/19)
  • Moana (2016),
  • Tūmanako (2017), and
  • Amīria (2018).
