Cape York (yet again)

I am off to Cape York again (this time with my parents and some of their birding friends) in early October. I have been up that way a number of times, though always in November so I have a few questions (though reading my previous notes I think I have answered two already). Is the McIvor River Crossing worth visiting in October (and even if going to Iron Range)? I think the answer is yes as this seems like the best spot for White-browed Robin though not certain how visible it will be at this time of year (any other potential sites would also be appreciated). I am assuming I am going to struggle some of the summer migrants (definitely Red-bellied Pitta, probably Buff-breasted Paradise-kingfsher) but what of the chances of some of the others such as Black-winged Monarch and even Pied Imperial-pigeon? (I have seen Metallic Starlings in Cairns in June so I am assuming that I will be able to find them). Are there any other species that are likely to be more difficult to find at that time in the dry that I should make certain I pay attention for? Finally, is there anything that is unliekly to be calling (particularly at Iron Range) that may be harder to find – my past experience there is that some species are easier to hear than see and if they are not calling they might be very difficult. Any comments on on peoples experiences on the Cape at that time of year would be greatly appreciated. I will send another post closer to the time for more up to date info on some species like Spotted Whistling Duck and Rufous Owl in Cairns, but any comments appreciated. Thanks, Peter
