Yellow-billed Kingfisher - Portraits and Profiles



I’ve twice been to Iron Range National Park (now Kutini-Payamu National Park) on bird banding trips. The first was in late November 2005 – the banner photo above shows our campsite at Gordon Creek. The second trip was at the same time of year but six years later, in 2011. The timing is very deliberate – intended to coincide with the very end of the dry season, so after most migrants have returned to the area if they’re going to, but hopefully also before the wet begins. If you’re still there after the first big rains you could be stuck there for quite a while as the river crossings become impassable.

Not that this timing has any relevance to the bird featured in this blog post. The Yellow-billed Kingfisher is resident in the area, inhabiting rainforest edges, tropical scrubs and woodland edges. It is a beautiful bird, not uncommon, and fairly frequently heard, but often difficult to actually see. This, together with its restricted range, makes it one of the key target species for birdwatchers venturing to the far north of Queensland’s Cape York Peninsula. 

When seen, the Yellow-billed Kingfisher is most often glimpsed in the depths of the rainforest vegetation.

Mostly they’ll keep to themselves, well hidden in the dense foliage of the lower to middle canopy. Even when nesting they have been described as non-aggressive and liable to desert the nest if disturbed (Reader's Digest 1976), but other evidence suggests they can be fairly pugnacious and won’t hesitate to make their discontent known if riled. David Hollands in his book Kingfishers & Kookaburras : Jewels of the Australian Bush (1999) relates eloquently and evocatively (as he does) some of his experiences trying to photograph nesting yellow-bills at Iron Range, and at 'Silver Plains' at the southern limit of the species’ distribution.

While banding along Portland Road in Iron Range National Park in 2011, we had a pair of Yellow-billed Kingfishers regularly taunting us with their calls, which are notoriously ventriloquial. Their call is a pleasant whistled usually descending trill, somewhat similar to that of the Fan-tailed Cuckoo. (And sometimes likened to a postman’s whistle – but I’ve never actually experienced the blowing of a postal worker’s whistle; well, maybe in an old movie I guess.) The birds were obviously fairly close, but proved proverbially difficult to locate. Eventually we did find the birds, in the canopy almost directly above us. They may well have ventriloquial calls, but I think they were also moving about a little ‘cause I really don’t think they were looking down haughtily at us for all of the time we were hearing them!

Later, the male joined her and they both watched us quietly as we watched them rather more excitedly.

Yellow-billed Kingfishers are about 20 cm in length. The male has a bright orange head, the female's is not quite so bright and has a dark patch on top of the crown. Both have dark spots either side of the nape. They feed mainly on insects, earthworms and small lizards. The nest is excavated in an arboreal termite nest, usually 3-15 metres above the ground.

They are also called Saw-billed Kingfishers because of the serrated edge to the upper bill (see photos below), and in New Guinea, where two of the three subspecies occur, they are also known as Lowland or Lesser Yellow-billed Kingfishers to distinguish them from their congener, the Mountain Kingfisher.

The Australian race, which occurs from the northern tip of Cape York to Princess Charlotte Bay, is known scientifically as Syma torotoro flavirostris. Syma is the name of a 'sea nymph' from Greek mythology (there is an ongoing theme of sea-based mythological personages and animals in kingfisher taxonomy for reasons which are best left alone here but well worth looking into if you have the time and inclination - Google, or try Australian Bird Names - a complete guide by Ian Fraser and Jeannie Gray, CSIRO Publishing, 2013 - it's a great read!). The specific epithet, torotoro, is from the local name for the bird in West Papua. René Lesson, the French ornithologist who named the species in 1827, claimed it was in reference to the birds' call. I must hear things differently! The subspecies name flavirostris means yellow-billed (surprise, surprise), and was given by John Gould in 1850 when he named the species Halcyon flavirostris, not realising that Lesson had already done the honours with the New Guinea birds. 



We were lucky enough to see Yellow-billed Kingfishers on both trips to the Cape, and band both  a female and a male in 2005, providing perfect opportunities to photograph the birds in the hand. I'll let the photos speak for themselves...

You'll never see eyes as beautiful as this on any other bird! I just wonder how they stop the mascara running in the humidity!

Cape Dragonflies



There are 324 species of dragonflies and damselflies in Australia! And over 5,000 worldwide. 

They all belong to the insect Order Odonata, which has an ancient lineage stretching back at least to the Upper Carboniferous 325 million years ago - they saw the dinosaurs come and go.

They can be divided into two distinct groups, the damselflies (Zygoptera), and the dragonflies (Epiproctophora = Epiprocta, formerly Anisoptera). In Australia, the damselflies fall into 12 families, and the dragonflies into 18 families (depending on which taxonomy you follow!).

Damselflies tend to be very slender, graceful, and generally hold their wings closed along their abdomen, whereas dragonflies are comparatively robust and hold their wings flat and perpendicular to their bodies.

On a bird banding trip come family holiday to Cape York and the Cairns area in far north Queensland in Nov-Dec 2011, I opportunistically photographed 12 of the 324 Australian species, representing one of the damselfly families and four of the dragonfly families.



Diphlebiidae
This is a small family, sometimes known as the 'azure damselflies' or 'rockmasters'. Unlike most damselflies, they hold their wings away from the body, like some sort of wayward helicopter, rather than closed along the abdomen.  It comprises just two genera: Philoganga from South-East Asia (4 species), and Diphlebia (5 species) which is restricted to the east coast of Australia except for one species that extends to New Guinea. Their habitat is streams and rivers.

The Tropical Rockmaster Diphlebia euphoeoides occurs in far north-east Queensland (and yes, this is the one that also extends to New Guinea), and inhabits streams and rivers, including those that may dry to pools. Mature males have extensively darkened wings; the first two photos below are of young males with relatively clear wings. Females are golden-brown in colour rather than the striking blue and black of the males. In my experience, which is limited, these appear to be quite common as I saw them at Mt Hypipamee on my first trip to the region in Nov 2005, and again at several places on the 2011 trip; always near fast flowing rivers. They're stunning!

Telephlebiidae
This family includes 39 species in eight endemic Australian genera (and as far as I’ve been able to determine only occurs in Australia). It is essentially a family of eastern Australia, though there is a single species in WA, and the adults are generally known as the ‘southern darners’. Its status as a family, rather than being treated as a subfamily of the Aeshnidae, is disputed by some. They are large, slender dragonflies that are associated with running fresh water from tropical rainforests to alpine environments, and even sand dunes.


The Green-striped Darner Austroaeschna forcipata occurs in far north-east Queensland, where it is largely restricted to rainforest streams. The one below certainly fitted this criterion as it hung immobile in the dense shade of rainforest plants adjacent to a tiny creek near our mountain accommodation in the Daintree.

Lindeniidae
This family, the ‘tigers’ or 'wingtails' is recently split from Gomphidae, an action which is far from universally accepted by taxonomists. They are medium-sized to large black and yellow dragonflies, with clear wings, and the eyes are distinctively widely separated, never meeting on top of the head. This latter characteristic is more typical of damselflies. The family is represented in Australia by just three species of Ictinogomphus, all endemic,  but the genus is represented by a further 13 species in Africa and Asia.


The Australian Tiger Ictinogomphus australis inhabits both flowing and still waters - rivers, riverine lagoons, lakes, and ponds - throughout eastern and northern Australia. The one below was photographed at the Cattana Wetlands in northern Cairns. 

The other two Australian species are more localised; one to the northern tip of Cape York, the other to the Pilbara.

Gomphidae
Commonly referred to as ‘clubtail dragonflies’, or just ‘clubtails’, this is a large family of about 90 genera and 900 odd species worldwide. They also have widely separated eyes. Most species are associated with flowing streams or rivers. Seven genera, of which five appear to be endemic, account for the 36 species in Australia.

The Zebra Vicetail Hemigomphus comitatus occurs along streams and rivers in far north-eastern Queensland. The ones I saw were on Woogabba Creek, in the rainforest to the east of Wujal Wujal and a little south of the Bloomfield River (the banner photo at the top of this post shows the habitat).

The Rainforest Vicetail Hemigomphus theischingeri also occurs only in far north-eastern Queensland, but unlike the Zebra Vicetail appears to be restricted to rainforest streams. I saw both the Zebra and the Rainforest together at Woogabba Creek.

Libellulidae
This is the largest family of dragonflies, with well over a thousand species in about 140 genera worldwide. It includes the ‘skimmers’, the ‘perchers’, ‘gliders’, and their allies, many of which are brightly coloured and obvious, and represent the most commonly seen dragonflies. Despite their prevalence, they are comparatively under-represented in Australia, which has a more Gondwanan bias to its dragonfly fauna, but there are nevertheless around 50 species of Libellulidae in Australia.


The Striped Swampdragon Agrionoptera longitudinalis is associated with shady pools and tree holes, again from far north-eastern Queensland, but also extending into New Guinea. The one below was in the same Daintree rainforest garden as the Green-striped Darner above - it was a very profitable two-night stay for us (or at least for my dragonfly photo 'collection') and lived up to its name of Eden Escape.

The Australasian Slimwing Lathrecista asiatica has a distribution stretching from India, through South-East Asia, to northern and north-eastern Australia; the Australian subspecies, festa, apparently being endemic. Based on the number of photos picked up by Google Images, this appears to be a fairly common species, and adults may be encountered far from water as well as near streams, rivers, lagoons and swamps. The ones I saw were in rainforest clearings at several places in Iron Range National Park (now called Kutini-Payamu NP). The females look quite different to the brighter red and green males.

The Green Skimmer Orthetrum serapia is a species that prefers a variety of still or sluggish waters, and is distributed from the Philippines, through the south-west Pacific, and across far north-eastern and northern Australia. It is markedly different in appearance to several other species in the genus such as the common and widespread Blue Skimmer Orthetrum caledonicum, a chalky-blue dragonfly (at least the male is) that I seem to see pretty much wherever I go. The Green Skimmer I saw, very briefly, was at the Cattana Wetlands in northern Cairns, and the posture of this one, in the only photograph I managed to get, made it quite difficult for me to figure out what species it was.

The Painted Grasshawk Neurothemis stigmatizans is another common dragonfly that I saw in lots of places around Iron Range NP, the Daintree region, and have also previously seen around Darwin and Litchfield National Park. They are very distinctive and immediately recognisable. They occur across the Top End and down the Queensland east coast (as well as to the north of Australia), breeding in a range of still waters, and are frequently seen congregating in clearings or grassy areas.

The Graphic Flutterer Rhyothemis graphiptera is also instantly recognisable and the ones I saw lived up to the name as they fluttered above and between the reeds at the edge of Lake Barrine in the Atherton Tablelands. They occur around riverine lagoons, lakes, ponds and swamps across much of Australia, and also in the Moluccas, New Guinea and New Caledonia.

I first saw a Yellow-striped Flutterer, Rhyothemis phyllis, at the settling ponds of the Lockhart River sewage works (sewage works are always a great place for birds and dragonflies!) and was stunned. I hadn't seen a dragonfly anything like this before, but it was early days and I saw lots more of them in various places over the course of the trip. This species prefers a range of still waters, and apart from occurring across the Top End and eastern Queensland, is also found from Burma (Myanmar) to the western and southern Pacific.

And finally, the Common Glider Tramea loewii. This is a very common and widespread species in Australia and, unlike most of the species featured in this post, I'd seen it many times previously in all sorts of places. This one was at the Cattana Wetlands in Cairns. They utilise a wide range of still waters but I've also seen them far from water and they are clearly happy to fly large distances. They have a wide distribution stretching from the Cocos Islands, across Wallacea and New Guinea, to New Caledonia and the western Pacific

My main reference for dragonflies is The Complete Field Guide to Dragonflies of Australia by Gunther Theischinger and John Hawking (CSIRO Publishing, 2006) - a really excellent guide and resource. They follow a tendency to 'split' families as taxonomic research advances, but as touched on above, the revisions are not necessarily accepted by all authorities (nothing new there!) For me, irrespective of any taxonomic or ecologico-political reasons, splitting at least gives a better 'feel' for the relatedness of the different species and groupings. 

Below I've included a table that I compiled, mainly for my own benefit, that lists the odonate families that occur in Australia and indicates the number of genera and species in each (also just for Australia - and bearing in mind that such numbers are constantly in flux, due as much to differences in taxonomic opinion as to advances in research, and are, in the end, and to use an often-used expression of a friend of mine, just a human conceit!).

Another great resource is the Identification Guide to the Australian Odonata put out in 2009 by the NSW Department of Environment, Climate Change and Water (available as a pdf at http://www.environment.nsw.gov.au/resources/publications/09730AustOdonata.pdf ), and it's worth having a look at  at Australian Damselfly and Dragonfly Photography at  http://dl.id.au/g.php?c=3

Happy dragon-watching!
