royal NP

hi all
my wife and i spent most of saturday wandering through the royal NP south of sydney. 
43 spp seen. full list follows.
on a beautiful clear morning, the carpark and clearing beside the hacking river at the north end of lady carrington drive were alive with birds, incl a gorgeous crested shrike-tit, topknot pigeon, satin bowerbirds, olive-backed orioles and an azure kingfisher. a strange but beautiful sight was pair of great cormorants sunning on a branch, heads cocked and vibrating their throat pouches in unison, giving the impression they were shimmering in the sun. is this a courtship display?
i also saw a little friarbird at close range. i know this is supposedly out of range. i grew up in an area where noisy and little friabirds were common and am v familiar with both. it may be possible they are spreading east/south due to drought etc. keep an eye out. there were little wattlebirds present elsewhere (everywhere) - the two are easily distinguished. 
Along the track we saw varied sitellas, striated thornbills, a brown gerygone, red-browed finches and a lovely male rose robin.  
At the southern end of Lady Carrington, it was pretty quiet but at long last we finally had a good look at a green catbird on a large log across the creek. quiet as a mouse but perhaps it was the time of day. 
an unplanned two-hour detour along the warramulla fire trail had its reward with a couple of sightings of a chestnut heathwren (tick) beside the track. 
no raptors and not many honeyeaters - apart from the usual suspects - despite the blossoms but a couple of YTBCs eased the loooong march along the road back to the car.
