- Cuckoos (I have only seen two species);
- Waders (especially migratory);
- Penguins (a trip to Penguin Island was a failure);
- Quail (and other small ground-based birds);
- Some of the more difficult water birds (Crakes, Rails etc).
A pelagic trip earlier this year helped me out in the seabird category, now all I have to do is organise some excursions to see some of these. Looking at the Birds WA Sightings page, now seems to be a good time for the cuckoos...
