Birding Target Groups

There are a few groups of birds that I haven't been very successful in seeing (and identifying).  The more obvious groups (parrots, finches, honey-eaters etc) are well covered in my list but the following are not:

• 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...
