108) The Tropics in Gurrung (Spring-ish)

An Azure Kingfisher surveys lunch options.


As the map indicates, this was our first venture into the 'tropics.' It's north of the Tropic of Capricorn. In the Bininj/Mungguy people's land of Kakadu, six different seasons are recognized --not simply the Dry and the Wet. Their knowledge of the natural world is fundamental to their culture, and they have deep awareness of the signs transitioning one seasure during the other. During Gudjewg (in the Gun-djeihmi language), monsoonal rains downpour for months and communities are isolated by the rising waters. We planned to visit during the hot dry Gurrung, when the birds would be crowding the shrinking billabongs (watering holes), prior to the Gunumeleng pre-monsoon storm season when the humidity rises, the clouds move in, and the electrical storms start in earnest. According to the Rangers, however, the start of the buildup was early - by 6 weeks! So we had heat (95 F) and humidity (85-99%). We dripped just standing still, making the pools we found to cool off in extra desireable. Also, it had been a wetter year, so the birds were not as concentrated as usual, but there were still amazing concentrations of some of the birds.

But first, Darwin. Even though it was late in the day when we arrived, we were off to a good start. We hired (rented) pushbikes (bicycles) so we could ride out to the East Point Reserve, where could view the sunset from the northern side of the continent--the Timor Sea. Here, we're closer to Indonesia than to Brisbane. We found interesting WWII remnants here. Darwin was an important base for activities against the Japanese in the Pacific. We read that Darwin was attacked many times during the War, and the memorials documented the tens of thousands of Ozzie POWs. Later on in our trip, we saw many old WWII airstrips along the highway out of town.


But before sunset, I was pleased to find the Orange-footed scrub fowl scrounging about in the leaf litter, especially since they are one of the cover birds on the "Top End" bird book I purchased. They are one of three specialized mound building birds in Australia that lay eggs in mounds of vegetation that they gather. The birds carefully monitor the mound to maintain temperature, humidity and aeration for incubation.








And a sociable Australasian Figbird. This boldly colored male looks entirely dis-similar from the female, I almost thought they were different species. These birds are in the same family as the orioles, but the figbirds are gregarious as opposed tho the more solitary Yellow and Olive-backed orioles.










We found 'accommodation' (a motel) near the Darwin Botanical Garden, so we could search for rufous owls early in the morning. Regrettably, the groundsmen said the usually-regular resident owls did not make an appearance at all this season. :o(. But these adorable double-barred finches were flocking nearby.


and there were Rainbow bee-eaters zitting about. How good is that?!


















These are some beautiful (unidentified by me) flowers Dirk photographed in the Botanical Gardens.
















Some type of wild-looking orchid.




























Then we headed from Darwin to Kakadu National Park, one of the few World Heritage sites listed for both its cultural and natural values.

We had a full agenda, ready to experience the culture, critters, and scenery of Kakadu.

A map of Kakadu.














And a Red-Tailed Black-Cockatoo!


















The indigenous people of this area have been integral to the planning and care of the park and surrounding areas, and the park is jointly managed by its traditional Aboriginal stewards and the Director of National Parks.

The marvelous museum at the Bowali Visitor Center in the settlement of Jabiru had this clever display to emphasize the need for us all to 'Look after this Country' (it's a mirror, and that's us reflected in the mirror behind the writing).













This was an exhibit at the little museum--the night creatures of Kakadu, including a Bush Stone-Curlew. They had recordings of the sounds the animals made at night, and we were lucky enough to hear the curlews one night. They put on quite a performance for such an unassuming-looking bird who tries to blend into its surrounds in the daytime (we saw a pair with a tiny fluffball baby)! Pizzey describes their voice as "a far-carrying, eerie whistling call (or chorus) that starts low and quietly--a drawn-out 'wee-eeer', repeated up to 5 times; rises, becomes a high-pitched, drawn-out 'keeleeoo', quickens, breaks, descends, often ends in a chorus of 'wee-wiff; wee-wiff; wee-wiff', by several birds. Other groups respond. Screeches in flight."


I'd call this a lotus flower, it may be the Red lily (Nelumbo nucifera), called Wurrmarninj in Gun-djeihmi language. These flowers grow in the waters of the floodplains and billabongs. The floodplains in Kakadu undergo extraordinary seasonal variation. The wet season inundates the lands to form a wide-reaching shallow sea. Over the dry season, the floodplains dry and crocodiles and waterbirds congregate in the shrinking wetlands for refuge.

Remember - this is serious croc country.......









This little splash of deep blue with white is a Forest Kingfisher.

















We went to Ubirr to gawk at the fascinating Aboriginal rock art sites.


A Thylacine--the Tasmanian tiger used to roam these parts!













We climbed the rocky lookout with the stunning sunset over the Nadab floodplain. The water glowed with the colors of the sky.
















We camped at the Merl campground so that we could get up early for meandering along the Bardedjilidji walk through the sandstone escarpment along the Alligator River in search of the chestnut-quilled rock pigeon, endemic to the region.

107.) Going North

Rainbow Pitta

We had time between semesters and headed north to Darwin and then Kakadu National Park - yet another World Heritage Area in AU. We carefully planned to arrive before "The Buildup" when the monsoons hit but the hot weather arrived 6 weeks early. It was 34 C (95 F) with 80% humidity! But that meant far fewer people.


Immense tracts of wetlands with thousands of birds.....and crocs


Comb-crested Jacana. Look at that foot! (made for lily-pad walking..)













Yes folks, this is serious "Salty" country (Saltwater crocodiles). Ever creek, every river, every lake boasted warning signs. You DO NOT go in the water (except in the Darwin municipal pool - which they check every day!) Remember the temperature here? You don't even get within 2 meters of the water in most places....















On the Yellow River we saw one of these guys every 5 minutes or so....If you *wanted*to, you could have tapped them on the head as they went past the boat!




Kakadu and the neighboring Arnhem Lands are home to amazing galleries of 20-50,000 year old rock art. We went to some less frequented places and were stunned.


We have just started classes, I have to move into a new office space, have papers to revise, reviews to do. Nancy is off at a 3 day class on regional ecosystems - things are a bit busy! We have hundreds of pics to sort and will get a sampling up as we can!

106.) Halfway around the world

Morning light on MP from the Watchman's Hut

I presented a paper at the Americas Conference on Information Systems - held in Peru. After traveling 1/2 way around the world I was not going to pass up the opportunity to visit Machu Picchu and climb Huayna Picchu (peak in the background).

But a full posting will have to wait until we return from the Northern Territory!

105) Dog Days of a Winter August

Pelican in Flight



Brown honeyeater



















Blue-faced honey eater


















Peaceful dove waking up - nice eyeshadow!

















Olive backed oriole - note the red eye!


































More strange OZ plants... Nancy will soon be able to identify these!

















Out on the unfortunately over-trampled spit there was a hatch of these butterflies - hundreds in the shade of the paperbark trees...



























Our local lorries tussling in the bird-bath. They put on quite a show!

104.) Return of the Tweed

Full moon rising over the Coral Sea


Dirk went birding on his own, since Nancy was attending a climate change conference in Brisbane, and found a prize Scarlet Honeyeater!

Here I wish I had bigger glass - all the old bird pros say you can get great photos with a 300 mm - you just have to sneak up on them. But these guys stay WAY up in the canopy. There is no way to get closer - you also don't get many chances - this is the first we have ever seen even though they are not particularly unusual.







There's always something wild and wonderful blooming at any given time of the year, here! Here's a Brown-headed Honeyeater caught between nectar snacks.












We're lucky to have Ospreys here, too! This one has successfully nested here for the last 6 years and it ready to fledge the chick (who would occasionally pop its head up).













With chicks in the nest! (at least I think that is the chick!)













A Sacred Kingfisher looking for second breakfast





















A pied cormorant keeping his eye on us















Suburban birding is entertaining as you also see bits of yard folk art--a weathervane on a house overlooking the broadwater
















Willy Wagtails seem to be habitat generalists--they live everywhere except the wettest forests. They're not very shy, and are always a fun bird to see.












The week's vegetable supply from a morning visit to the glorious farmer's market! Remember that we just passed the Winter Solstice? There are some benefits from living in a subtropical locale! It's difficult not to "impulse" buy veggies when they're this beautiful!







Where is that Molly cat?!

You can't see me if I can't see you, right?!






















So many birds to see - can't wait till spring when things get a bit more active. Though one of the locals told us she had ID'ed 72 species that morning (we only had 34). I can only get photos of 20% or so ---
