January Wildlife Report

North Lakes Town Park
'Lifers', Migrants and Climate Change.

It's been a great start to the year for wildlife watching in South-East Queensland, especially for bird life. As this is therefore a 'bird heavy' post, I've shared this with 'Wild Bird Wednesday', Stewart Monckton's excellent weekly collection of bird blogs that you should check out if you haven't already. This month I saw two new 'lifers' (ie. species I've never seen before) in the one location - the Moreton Bay Shire suburb of North Lakes. Sighted there earlier in January was a White-browed Crake (Porzana cinerea), a tropical species usually only found in the far north of the continent. Birdwatchers raced to the area after the bird was reported, in order to get
a glimpse of this highly irregular vagrant. Unfortunately the bird had moved on immediately after that initial sighting, but while I missed out on one Crake species, I did enjoy great views of another  - the Baillon's Crake (Porzana pusilla) - that was a first for me.

Also swimming about on the same lagoon was one of Australia's rarest waterfowl (and my other 'lifer') - the primitive-looking Freckled Duck (Stictonetta naevosa).

I'm not sure why such uncommon waterbirds should be so easily found in this recently-established housing development. It is possible that they were already here before the bulldozers and concrete-mixers moved in, and careful landscaping and environmental management has allowed them to persist. The area is also well-known for being one of the few busy suburbs of Brisbane where Eastern Grey Kangaroos (Macropus giganteus) still roam freely, though car-strikes are an increasing problem. Anyone wishing to know more about the wildlife of North Lakes, or what they can do to help regenerate the environment there, should look up the 'Mango Hill & North Lakes Environment Group' on Facebook.

Elsewhere in Brisbane, migratory summer visitors are making the most of the sunshine.

Dollarbird, Alexandra Hills

While scouting out an Alexandra Hills location for a frog survey, the open eucalypt woodland there came alive with the spirited cackling of Dollarbirds (Eurystomus orientalis). This migratory species is a member of the Roller family, a group of birds named after their twisting, turning flight habit. Probably the most famous representative of this group is the Lilac-breasted Roller (Coracias caudatus), a gorgeous multi-coloured bird often seen in the holiday photographs of those returning from an African safari. In good light, the Australian species is a colourful bird too, though the block-headed silhouette alone is distinctly recognisable.

Other summer migrants don't reveal themselves in such a free and easy way. In the woodland shadows right now lurk several Cuckoo species, usually noticed by their whistling calls and dipping flight. At Melaleuca Environmental Park earlier this month, these clues led me to a good view of a Shining Bronze-Cuckoo (Chrysococcyx lucidus) as it made a meal out of a caterpillar. Cuckoos keep to the shadows because other birds harass them greatly - understandable, given the parasitic nature of most species. This time of year sees young Cuckoos leave the nest they were raised in, usually to be fed by their host parent for a few more weeks to come. A brilliant example of this was seen on the Sunshine Coast recently, where this fledgling Australian Koel (Eudynamus orientalis) had its every need and whim attended to by Magpie-Lark (Grallina cyanoleuca) parents.

Migration is not an easy or risk-free undertaking in nature, and in the case of highly mobile animals like birds, accidents do happen. Franklin's Gull (Leucophaeus pipixcan) is usually an American species that moves seasonally between North and South America, yet an individual bird has turned up in South-East Queensland. Reported by Doug Armstrong on the shores of Lake Barambah, the bird has put many birdwatchers into a frenzied migration themselves, heading out to the South Burnett region to find the rarity.

Other migratory shorebirds seen this month include a large mixed flock of Red-necked Stints (Calidris ruficollis), Ruddy Turnstones (Arenaria interpres) and Common Terns (Sterna hirundo) at Scarborough Boat Harbour.

Around the rim of the harbour, a picnic area turned up more than just the usual suspects, by way of Australasian Pipits (Anthus novaeseelandiae) and a family of Buff-banded Rails (Gallirallus philippensis).

Daily temperatures have been excruciatingly hot on some days, soaring up to 38C (100F). At this time of year, wildlife-spotting is best undertaken around dawn or dusk, when the heat is at its most bearable for animal and human-kind alike. On one such early morning walk around Melaleuca Environmental Park in Lota, a European Hare (Lepus europaeus) almost bounded in to me as I quietly observed a Goliath Stick Insect (Eurycnema goliath) in a flowering shrub.

Of course, the other way to beat the heat is to head to the beach, so I've also been spending time on North Stradbroke Island. The hot weather mixed with intermittent storms resulted in a terrible bush fire there earlier in January, where sixty percent of the island was left scorched. Signs of this destructive event were evident during my trip to the island, with many trees blackened by the flames between Dunwich and Point Lookout. Wildlife on the perimeter of the island was spared, and this Osprey (Pandion haliaetus) on Point Lookout was in fine health when I visited.

While heatwaves and bush-fires in and of themselves aren't indicative of the phenomenon we call 'Climate Change', us nature-observant folks may see it manifest in other ways. In recent years, some migratory birds appear in our cities outside of their usual 'timetables' for example, or tropical species establish themselves in latitudes formerly considered more temperate. An example of the latter was noted during my time on North Stradbroke, when I stopped to explore the rockpools off Frenchman's Head. The video I filmed there reveals several fish species, including tiny Convict Tang (Acanthurus triostegus), Grey Demoiselle (Chrysiptera glauca), a Peacock Rockskipper (Istiblennius meleagris) and several dominant Banded Sergeants (Abudefduf septemfasciatus). The Sergeants are tropical fish recorded from as far south as the Great Barrier Reef, yet here in a rockpool outside of this documented range is a population that appears to be engaged in territorial breeding behaviour. It will be interesting to note which species expand or reduce their range in the coming decades, in response to climactic fluctuations we are likely responsible for.


Until next month, enjoy Wild Brisbane!

  3. Absolutely amazing shots. Oooo's and Ahhhh's from over here other than the Freckled Duck who made me laugh!

    1. Thanks Em! You'll be amused to know the other name for the Freckled Duck is 'Monkey Duck', because it climbs up to its nest through river branches instead of flying.

    1. Thanks Adam, I was really happy with that one! Crakes aren't usually known to sit in the open sunlight and show off their feathers :)

  5. Some of my favorites are the Crake and the Kingfisher. Wonderful collection of birds.

  7. A very informative read Chirstian. I like your description of the Freckled Duck as primitive looking- you're right. It's interesting that thestill being fed juvenile Koel has so many adult feather already but being ighly conspicuous otherwise it makes good sense to become unobtrusive? The stick insect does indeed look goliath and I'm wondering how big they grow?

    A nice post.

    1. Thanks Phil! The Koel actually looks like it is a male as it has random dark feathers coming out on its body. The pretty pattern you see here is just a cryptic juvenile colouring to help it hide in the mottled shadows of a tree - the adult male is glossy black all over. The juvenile does look conspicuous on a driveway though, i'll give you that! The Stick Insect was about 20cm long but they can get even bigger!

  8. Your photos are lovely. There is nothing like the Australian wildlife! I am now feeling homesick!

  9. Great set of pictures - the Koel and the MPL is a great picture.

    Hope joining in WBW was not too scary!

North Queensland Trip, Part 1.

Eungella National Park Eungella National Park location; Image courtesy of Google Maps. My home state of Queensland is a huge place. Bigger than any of the United States, it is considered the sixth largest sub-national entity in the world, behind such remote provinces as Nunavut in Canada, and the Danish territory of Greenland. Though I've lived in and travelled through Europe and Canada, much of my birthplace remains a mystery to me. To rectify this situation, I planned a road-tripping holiday this year with my sister and her partner, in the Northern section of the state. My first visit to anywhere in the Tropics, I have since returned home with some of the most amazing wildlife experiences possible!

Wild Plants of Ipswich

I've never really taken much notice of plants until recently, regarding them usually as just the thing that a bird perches on while you're watching it. This week I decided it was time to change that attitude by trying my hand at plant identification in Denmark Hill Conservation Park, located in the centre of Ipswich. The park is just 11.5 hectares in size, but preserves a patch of bushland that acts as an 'island refuge' in a sea of suburbia. I did my best to focus on the trees and not be too distracted by birds or the resident Koala   (Phascolarctos cinereus)  population, and came up with nine interesting trees and plants seen on the Water Tower Circuit.

Wild Queensland: Photos and stories from my roadtrip north

Earlier this month, I drove up to Airlie Beach in the Whitsunday Region to celebrate the 40th birthday of my close friend, Kat. Photo by Luke Martin. Our time there overlapped for one weekend, in which we enjoyed swims, drinks, hearty dinners and a sailing adventure around the islands. The celebrations and wonderful catch-ups flew by quickly, but when Kat and her husband Luke flew back down south on Sunday, I still had a week's worth of time at my disposal to explore the nature of Queensland's coast. I started with a journey into the forests of Conway National Park, just a ten minute drive east of Airlie Beach. I spent a sunny, humid morning walking up to the peak of Mount Rooper, through vine scrub and eucalypt forest. It was exhilarating!  I immediately saw a new species of bird for me in the carpark there, a female olive-backed sunbird (Cinnyris jugularis). After so much rain earlier in the week, the forest floor was also teeming with amazing fungi! After lunch back in town,
