Perth Hills Flora - Gallery 4

In this, the fourth gallery of wild flower shots from the Perth Hills in Western Australia, I show a selection of backlit images. Much of the colour in the plants are washed out when in the full harsh sunshine of the Australian bush, but in the early morning or late afternoon the light is softer and at a favourable low angle. Although, even then, some shots are too well lit in over the shoulder light shots. So, I prefer to shoot into the light and capture the details high-lit by the same harsh light from behind the subject. This is what I tend to see anyway. I seldom take wide landscape shots for the same reason, preferring to zoom in on a detail, or several details that make up the whole. So here in this gallery, I show what I saw when walking through the Perth Hills bush into the sun.

Perth Hills Flora - GALLERY 3


Pink Enamel Orchid Elythranthera emarginata
The petals really loook like they are glazed - and this one a bit chipped


Scented Sun Orchid Thelymitra macrophylla
These were growing on metre-tall stems
They open in the sun, hence only a few were fully open in the dappled woodland light


Blue Lady Orchid Thelymitra crinita
There were blooms about every 10 m as far as I could see


Purple Flag Patersonia occidentalis
Not an orchid, but just as colourful


Black Eyed Susan Tetratheca hirsuta
These flowers are typical of the species, hanging down rather than facing up into the light


Gompholobiuim shuttleworthii
One of two pink members of the Pea family, Fabaceae, in the Perth Hills


White Banjine Pimelea ciliata 
Like many of the common shrubs, these flowers are worth stopping to look at closely


Hibbertia pachyrrhiza
A low ground creeping species, hiding in the undergrowth  


Hairy Yellow Pea Gompholobium tomentosum
A yellow shrubby member of the Pea family


Bristly Cottonhead Conostylis setosa
Only a few centimetres high but it catches the eye


Bristly Yellow Featherflower Verticordia acerosa
The pollinated flowers turn red, emphasising the yellow of the fresh flowers


Beaufortia macrostemon
A member of the Myrtle family with no common name
The whole bush was aflame

Red and Green Kangaroo Paw Anigozanthos manglesii
These are a symbol of the Western Australian flora - here in setting sun


Many-flowered Fringe Lily Thysanotus multiflorus
A small individual plant growing afresh after a forest fire


Climbing Fringe Lily Thysanotus scaber
This one is trailing along the ground as there were no shrubs nearby to climb over after a forest fire


Milkmaids Burchardia multiflora
Flowers and forming seed-pods


False Blind Grass Agrostocrinum hirsutum
Easily mistaken for one of the blue orchids


Billy Buttons Craspedia variabilis
A simple composite flower


Everlasting Daisy Hyalosperma cotula
These are about to open into bloom, they grow low in scattered groups, carpeting open clearings 


Yellow-eyed Flame Pea Chorizema dicksonii
Over forty species of the Pea family, Fabaceae, grow in the Perth Hills


Crinkle-leaved Poison Bush Gastrolobium villosum
The poison is monofluoroacetic acid, the main active constituent of 1080 poison  


One-sided Bottlebrush Calothamnus quadrifidus
Last year's fruit and this year's flower


Prickly Hakea Hakea amplexicaulis
New fruit forming


Hakea fruit opened after a forest fire
Wavy-leaved Hakea Hakea undulata

West Australia













I have been back from Western Australia for a week or so now and it has taken a while to catalogue the thousands of photographs I took on the trip. Although I was there to help Simon with his eagle studies (see previous post), it was impossible to not notice the wealth of wild flowers that were in bloom as we walked through the forests and heaths in the Perth Hills. WA is famous for its wild flowers and many were new to me as I live in eastern Australia where many of the flowers differ from those in the west. So, here I have selected and posted a some shots that give an impression of the variety of colour and form of those plants. There is a set of ten pictures in this first gallery and more will follow as I slowly progress through the catalogue. Only the species names and a few notes are given. This not an intense post, I simply want to share their beauty.

Wedge-tailed Eagles in the Perth Hills

A nine week old wedge-tailed eagle Aquila audax chick on its eyrie


I have been over in Western Australia for the past week helping Simon Cherriman ring/band and satellite-tag wedge-tailed eagle chicks for part of his PhD study on the species'  behavioural ecology. As this is Simon's study, I will only post a few snippets here to give a picture of the birds; how we ring them, their habitat and prey. To read more on Simon's work please visit his website at simoncherriman.blogspot.com.au.



The wedge-tailed eagles' habitat in the Perth Hills is mostly woodland with open patches of heath, so there is considerable cover for potential prey species. This is quite different from the more open landscape of central Australia, or the open hillsides which golden eagles live in in Scotland. There is a chick in an eyrie on the right of the photograph.



Simon measures the bill of a young wedge-tailed eagle.The sex of even young birds can be determined by the size of their bills and feet relative to their age.The females are larger. Bill Brown, who has also been helping Simon, holds the chick firmly but gently. He is well-accustomed to handling eagles as he has studied them in Tasmania.



This chick was about four weeks old. At this age the chicks are still mostly covered with white down, with only the first brown feathers opening from their quills on their wings and tail.


Simon pulls himself up by rope to reach an eagle eyrie. Although this looks easy with modern climbing equipment, Simon also makes it look easy because he is one of the best, probably the best, tree-climber I have seen, whether free-climbing or with technical aid.



The Perth Hills eagle study area is only about 30 km from the city centre of Perth, less from the airport. A Qantas flight passes overhead; there seemed to be a flight like this every few minutes while we were at this nest site.


The eagles appear to select the largest trees in their territory to nest in. Often these are remnants of the once widespread forest which would have been mostly of such grand trees as Jarrah Eucalyptus marginata, Marri E. calophylla and Wandoo E. wandoo. This nest was about 25 m from the ground, similar to most of the nests in the area.



While at the nest sites, we searched around the base of the nest trees and any other perches in neighbouring trees, looking for the remains of prey. At this nest site there were remains of a minimum of two Red-tailed Black Cockatoos, three Kookaburras, one Australian Magpie, one Australian Raven, twelve Shingle-back Lizards and two young Western Grey Kangaroos. These are all woodland species and the eagles possibly catch the lizards after watching from perches in the high trees. We do not know if the birds are be able to see the understorey where the shingle-backs live from high in the sky. However, Simon's study should reveal just how the eagles hunt, as the tags measure the height that the eagles fly at. So for now this is only my supposition.



The four week old chick is here placed in a bag ready to be lifted back into its eyrie. This bird has a standard numbered metal ring on its right leg and a coloured metal ring with a unique number on its left leg which is more easily read in the field or caught on camera.



Simon checks that a larger chick, which has been fitted with a satellite-tag, is alright before he abseiled back down out of the tree and we left the bird to settle down. Satellite-tracking of eagles and other birds is a well-established method for finding out where birds move to, revealing where they hunt and whether they migrate or wander nomadic-ally, and if so where to. The full details of this birds movements will be analysed by Simon as part of his study, but meanwhile a sample of the information he has collected from previously tagged eagles can be read on his website as linked above. And I am sure Simon will post snippets of information on this bird's movements as soon as he can.
