Broome 2017 _ Wave The Waders Goodbye _ Day 06

Day 06

This was the last day of the course. Our excursion today was to visit the sites and sights around Broome itself. Birds seen included Red-headed Honeyeater, Little Curlew, Striated Pardalote at the Water Treatment Plant but no Semi-palmated Plover, Ruddy Turnstones and Pacific Golden Plovers within sight of nesting Ospreys on the docks and the obligatory Tawny Frogmouth in a tree in the Woolworth’s car park. It was in the same tree as in November last year at Ashmore Reef Pelagic time.

Tawny Frogmouth Podargus strigoides

Back at base it was Wader Watch time. I went down to the cliff top a bit earlier. Whimbrel, Ruddy Turnstones, Marsh Sandpiper featured for me. The others arrived and we concentrated on watching waders looking to see if they were lining up on the mud, listening to the calls. Sometimes there would be false take offs where birds would lift off, sometimes quite high [5-700 metres] and in good numbers [50-100] and you would reckon, “That’s it. They’re off”, but, no, suddenly they would all come back down. It was as if no one individual bird felt competent or ready enough to lead off heading north with the setting sun on its left shoulder. Another day done.

Here are views of the bay at low tide. The guys in the boat just had to wait for the incoming tide. It was a ten metre difference between low and high tide!

The birds are well spread out at low tide. Just a few Eastern Curlew in view. These would have been 500 metres away.

We wondered if an Eurasian Curlew may have been present. At these distances, the only distinguishing mark would be  a clean white rump for the Eurasian so plenty of flight shots were taken. No Eurasian Curlew detected.

Eastern Curlew Numenius madagascariensis

But some birds do come closer.

Marsh Sandpiper Tringa stagnatilis

These need to be differentiated from Common Greenshank. The Marsh is quite a bit smaller and has a white rump and wedge up the back (see image 3). Q. What are the two birds at the back?

Day 04

Birding at dawn anywhere is usually pretty good, especially on a calm morning. The BBO has a couple of paths through the bush to take. This morning I came across a small flock of Red-winged Parrots.

Red-winged Parrot Aprosmictus erythropterus
Male first image, female in other two.

The trip for today was out onto the flooded Roebuck Plains. Flooded enough that we didn't leave the safety of the tarmac of the Northern Highway.

Black-winged Stilt (White-headed Stilt) Himanoptus leucocephalus

Plumed Whistling-duck Dendrocygna eytoni
And one lone Australian Wood Duck Chenonetta jubata on the left.

White-winged Black Tern Chlidonias leucopterus Coming into breeding plumage

Black-tailed Godwit Limosa limosa

Glossy Ibis Plegadis falcinellus

Brown Goshawk Accipiter fasciatus
Secondaries not bulging beyond trailing edge of wing. Plenty of tail behind feet. Tail rounded as the outer retrices on BG are shorter as they go out from the midline. Juvenile bird.

Little Friarbird Philemon citreogularis

This, and the following two birds, were seen at the Roebuck Bay Roadhouse.

Pied Butcherbird Cracticus nigrogularis

Australian Magpie (Black-backed) Cracticus tibicen eylandtensis
This subspecies of magpie has white trousers and is found on Groote Eylandt in the NT and the Kimberley area.

Roebuck Bay
The view from the observation station [chairs on the cliff top!] towards dusk. The colours are just stunning. There is no way that any of my images do it any sort of justice. The first image is off to the left of our position looking directly down the light whereas the second is looking across the light to the southern end of the bay.

The reason that so many waders are here is the amount of food it produces aided by a variance of up to 10 metres between high and low tide. It is shellfish heaven -- both for birds and humans. These lads were crabbing. 

Here are some images of the main reason we were there. Watching and recording the species and numbers of birds heading off northward on their migration.
