Fri 10Grey Falcon
12 Km west of Ashburton Station
At about 12 km west of the Ashburton Station homestead as we came slowly up a rise from a watercourse a medium to larger sized raptor swooped low in front of the car right to left. It had grey upper wings and yellow beak and feet. During all the time we observed it, it paid no heed to our presence. It continued its low slow swoops up, then over the ridge and out of sight. We drove up the ridge to the flat ground above it and picked up the bird to our right. The vegetation was sparse with most scrubs to 1-2m and occasional small trees to 3m rarely 4 m tall. As it moved to our right at scrub top height the first thing we noticed was the open dark charcoal grey finger like feathers on its wing tips. It begun working a small area. It would slowly glide at scrub height between the taller trees then gracefully, and slowly, turn and swoop down into the lower bushes and out of sight, only to reappear slowly swooping up again gliding, turning swooping down again, etc. It’s circular flight path had it eventually returning to rework the same areas again and again. Most of the time it’s wings were outstretched, the darker wing tip feathers open, it’s yellow legs hanging down and its talons open. Any pyjamas were not noticeable. On a couple of occasions it dropped straight down out of sight (to capture prey?), and rose up again with nothing in its talons. We were so surprised and captivated by this display that I didn’t think to get my camera and some photos. But we did get an excellent view of all its features. It’s upper body wings were a slightly blue/slaty mid tone grey. More grey and less brown than shown in Morcombe. The top part of its head darker but the rest white with a yellow beak extending to a narrow darker ringed yellow eye patch. The underside of it’s tail with light but distinct darker cross bars. Its underside lower wing feathers lightly but not very distinctly patterned. Its upper wings breast and rest of its body white without discernible markings.

Thu 9Black Grasswren
Mitchell Falls NP
Spotted through bins while panning rocky ledges and boulders at 6:10am at Little Mertens Falls on left side of the outcrop where found in the past by others. That was after 20 mins of searching with Ian checking other side of Falls. No luck searching LMF and further afield for 5 hours the previous morning. A female I think based on bright rufous orange lower body. Head and chest blackish. The Grasswren was standing on the front of a large flat rock half way up the outcrop nearly, facing towards me (the Falls). A very happy 2 minutes watching it standing tall as I failed to see one 7 years ago. Planes and helicopters start up around 6:45am and go all day! Campground packed out as well. Worth the 3,000,000 + corrugations! Two Monjons also seen in the same outcrop.
