For a while now I've been wondering whether it is feasible to see 600 species in Peninsular Malaysia - that's 91% of the total list ever recorded (currently 661).

This is a selection, not every bird on the Peninsular Malaysian list I haven't seen. The photos were all taken outside Pen Mal (obviously!), in Singapore, East Malaysia and Thailand. The list includes a few embarrassing misses, but most resident species on the list read like a who's who of the most difficult ones to see in the Peninsula these days.
So - can anyone help me plan my itinerary over the next twelve months?!
