Upcoming CPD Activity for IRBPP Members: Eastern Grass Owl Research
Available January 2025

Authors: Ric Dunlop and Philip Pain

We pleased to announce a new Continuing Professional Development (CPD) activity focused on Tyto longimembris, or Eastern Grass Owl. This activity will be available to all members in the Quarter beginning January 2025.

The Eastern Grass Owl, though widespread across the Indian subcontinent, Southeast Asia, and northern Australia, remains under-researched in the wild. This CPD module will present findings from a key study, initiated in 1996, which successfully bred birds acquired from the wild. The study offers valuable insights into the species’ reproductive ecology, highlighting clutch sizes ranging from 7 to 10 eggs, incubation periods of 29–31 days, and fledging success rates between 50% and 75%. Fertility rates within clutches were also examined, revealing variation based on seasonal timing, with later clutches showing lower fertility.

Of particular note is the observation of cooperative breeding behavior, with female offspring from previous years participating in incubation and chick-rearing activities.

An abstract and short synopsis will be available to non-subscribing members in the ‘Free stuff’ area.

Subscribing members will get detailed access to the research and comprehensive notes on this fascinating study of a little known species. Your activity will be automatically recorded in your personal CPD log managed on your behalf by the IRBPP. CPD Hours will be automatically awarded for completing this activity
