Black-winged Monarch, Chestnut-breasted Cuckoo
McIvor River causeway, north of Cooktown, Queensland
In an effort to establish what is known about Black-winged Monarch in Australia, I have been studying this species here at my study-site sparodically since 2005, with 4 visits there this year alone. On my first mid-winter visit this year, I noted that this species here is obvious in it's absence of calls - contrary to the warmer months when it's calls are a feature of the immediate area. This species is documented as being a migrant that returns to NG for the cooler months. You can imagine my surprise when I had an adult Black-winged Monarch flying over the rd, just above head-height at 9:30am on Monday 11/06. Not one individual called for the duration of my visit - maybe more birds are there, living quietly...?!
A species that was very vocal during this winter visit was Chestnut-breasted Cuckoo, continuing from it's noisy advertisements throughout the warmer months at this site & nearby. I've attached a rough image I took of an adult calling some 40mtrs above me - clearly showing the diagnostic tail pattern which distinguishes this species from the larger but otherwise very similarly plumaged Fan-tailed Cuckoo. There were at least 4 Chestnut-breasted Cuckoos calling at the causeway with many more in the general area.
Good birding was had with many species quieter than usual but nevertheless still there.

5.30pm this afternoon a Grey falcon was observed in pursuit of a Black Faced Woodswallow just above the treeline in the CSIRO block along Heath Rd. It failed in the attack and flew off towards the Todd River, flying directly over the top of "Pathdorf ", a Bed and Breakfast at the end of Heath Rd.
