 I'm THRILLed to announce that after many, many years in the making, my Nest-box/Tree-hollow book is very close to completion! "Hollowed Out?" is a story about the journey hollow-dependent fauna living in south-west Western Australia have endured, and how nest-boxes not only help these important animals survive, but foster custodianship for them into the future. It contains a wealth of information about habitat trees, the hollows they form, how human activities have impacted and continue to impact these precious natural resources, and, most importantly, the most up-to-date designs for a range of wildlife nest-boxes you can build in your backyard!

I had hoped to time the launch of this book with my appearance on the ABC TV programme Gardening Australia, which aired on Friday 22nd October as part of National Bird Week (you can watch this story, named 'Bird Box', by clicking here). But as often happens with creative projects, a few delays emerged so it wasn't ready in time. 

After the initial launch of a paperback book, "Hollowed Out?" will be launched as an e-Book, to allow a fast, green way of getting it out there as far as possible!

MORE nest-boxes for Porongurup Carnaby's Cockatoos

If you saw the 2018 news post containing an update on the success of our Carnaby's Cockatoo nest-boxes in the Porongurups, you might be as thrilled as we are to know that a recent grant provided by the Foundation for National Parks and Wildlife has seen FIVE more cockatoo boxes added to this breeding site! The latest installation brings the total number of cockatoo breeding sites now available to 12: one natural tree-hollow and 11 nest-boxes. I have just returned from the Porongurups after installing the new boxes and was excited to have observed female Carnaby's Cockatoos emerge from two of the existing nest-boxes, suggesting incubation has already begun for two pairs. At the end of 2019, all seven sites were occupied and five pairs fledged chicks. With five new, vacant sites now available, we are looking forward to seeing how many pairs of this precious, Endangered species breed in 2020!

To see a video documenting the early success of nest-boxes at this site, which includes footage of the cockatoos and a beautiful nestling, click here.

Waalitj Boodja

I was recently accompanied on a Waalitj / Wedge-tailed Eagle colour-banding mission by two very special people: my friend and bush photography companion Andy, and his young niece Eia, an incredibly talented artist whose enthusiasm to help the environment saw her design, produce and sell some unique 'eagle cards' to raise money towards my eagle research. Eia had heard all about my visits to eagle eyries in the Perth Hills and I had long promised to take her to one. Fortunately Andy is also a highly accomplished filmmaker, which allowed this short snapshot of the colour-banding component of my research to be produced and shared with others. Please visit Andy's website and Youtube channel to view and endorse more of his work, and you might wish to follow Eia's work on here on Instagram. I hope you enjoy!

Hack and Counterpoint

This past week has been another busy one with regard to media interest in the East Gippsland eagle poisoning, and I've been glad to provide information in interviews on two ABC programs that have recently gone to air.

It was great speaking to Amanda Vanstone on her Radio National show Counterpoint which was played yesterday, because there was plenty of time to provide important background information about eagle biology which is relevant to the poisoning episodes. If you visit this link and fast forward to 41:30, you can hear the discussion.

I also had a chat to Tom Tilly on Triple J's Hack program last week, which felt a little daunting because it went live to air! But again there was enough time to make the key points necessary and I was very pleased that most people who called in to the show were sympathetic to eagles and saw the need to protect them. You can read this article by Jo Lauder, which also contains a link to the list of previous shows, or you can go straight to the "Driverless cars, platonic friendships and why farmers are baiting Wedge-tailed Eagles" episode.

Kalamunda Eagle Extravaganza

Last night I delivered the reward to the City of Kalamunda for their pledge to last year's 'Where's Wailitj' crowdfund, in the form of a public presentation and workshop on the FULL suite of Wailitj / Wedge-tailed Eagle information in my vault! It was exciting to arrive early at the venue and build a life-size Wedge-tailed Eagle nest, then have Noongar elder Dr. Noel Nannup arrive to be in some photos and open the evening by presenting a wonderful Welcome to Country. Yvonne from the WA Birds of Prey Centre also swooped in for a quick visit with Micro, an adult male eagle who delighted the children attending with his affectionate nature and willingness to allow them to get up close and personal.

It was wonderful to be sent the following feedback letter, written to the City by some very happy participants. I am always thrilled to receive such feedback, because my talks often have so much in them and the time goes so quickly, so it's not easy to know how they have been received.

Keep an eye on my Instagram and Facebook pages for information on future public presentations.

"Good evening,

Please convey my utmost thanks and sincerest congratulations to all staff from the City of Kalamunda who were involved in organising and presenting the Eagle Extravaganza. My two grandsons will never forget the day they were able to have an eagle stand on their wrist then stroke its chest. Please extend our thanks to the lady who was the eagle handler.

Noel Nannup had us in the palm of his hand as he spoke of his Ancestors and  Country. Simon Cherriman was an inspiration with his passionate stories of our beautiful local eagles and their lives as well as his deep interest in our Natural Environment  and our Indigenous people. Afternoon tea was bountiful and very welcome after school on a winter's day. All in all we were inspired as well as entertained as Simon offered his incredible insight into the life cycle of our great wedge tailed eagles.

Congratulations to all involved. Many thanks to the City of Kalamunda Environmental Staff,

Sue, Jack and Max"

Eagles Die Hard but Old Habits Do Not

This Wedge-tailed Eagle was satellite-tracked from Perth to the Pilbara and died of injuries (chopped wing feathers) suspected to have been sustained following a collision with an aircraft or drone.

The news has been spreading like wildfire so you're probably well aware about the mass-culling of over 130 Wedge-tailed Eagles in East Gippsland, Victoria. This isn't the first case of suspected raptor poisoning in East Gippsland, with several White-bellied Sea Eagles testing positively to organochlorine last August. Since this recent story was released last week, ongoing publicity around the issue has sparked debates about eagles, lambs and what should be done when wild animals protected by legislation come into conflict with human interests.

There are a number of points that need clarifying (as always is the case, because of the simplification that often comes with rapid and concise communication), so I felt the need to post this update to offer a resource that can hopefully prevent the evolution of more myths (huh, one can only try! In fact, read all the freely available information on my websites, which might cull 130+ myths. Legally, of course). I have researched eagles for over two decades, during which time I have been fortunate to be mentored by some of the world's leading experts on this group of amazing raptors, and while I certainly don't know everything there is to know about their biology (the eagles, not the experts), I am amazed by how little of the basic information many people seem to know, and by the speculation and sheer lack of environmental understanding demonstrated this past week!

Firstly, 130+ eagles were not culled last week. The news was made public last week, but this is clearly an example of ongoing, systematic persecution which has involved culling birds over a period of several years. So, questions like "why were so many eagles in one place at once?" and "how did someone kill so many so quickly?" can be put to bed.

Secondly, people have again started debating whether or not eagles kill lambs. This issue is discussed more deeply in a very well-balanced piece published by Australian Geographic late last week, including immensely valuable comments from leading Australian raptor biologist Dr. Stephen Debus. Key points discussed here are:

- eagles are mammalian predators capable of killing lambs, but repeatedly evidence has suggested they are rarely the prime cause of deaths, which are more often attributable to foxes, crows, poor weather and mismothering.
- even in cases where eagle predation is documented, the costs of having them taking some potentially viable lambs are far outweighed by the benefits these predatory birds deliver through predation of pest species, and removal of disease-harbouring carrion.
- no economic impacts to the sheep industry have ever been proven to be caused by eagles.
- there are many alternative solutions to culling or 'legal' (i.e. with a permit) killing (read on!).

To clarify an important ecological point regarding the behavioural differences in the two broad 'types' of Wedge-tailed Eagle present in our landscape (1: sedentary, breeding adults, and 2: nomadic, non-breeding juvenile/immature birds), I responded on Tuesday to interest from The Conversation who published this article that I co-wrote with one of their editors. Breeding adults may occasionally take lambs (viable or otherwise) as nesting food, but this is rare and smaller vertebrates are preferred. Juvenile eagles are drawn to abundant prey sources and can sometimes accumulate in larger concentrations (dozens or more). Such birds may simultaneously attack larger animals, which can be perceived as 'pack hunting', but there is no evidence these attacks are coordinated. It is these birds which seem to have mostly been the target of the recent cull. I also published this article to raise awareness about the potential impacts to the population of a native predator that, as my recent satellite-tracking research has confirmed, can in its juvenile dispersal phase move such enormous distances. This means:

- EAGLES CULLED in East Gippsland could essentially be born ANYWHERE in Australia.
- ecological sinks created by humans are never a good thing, but to think the Gippsland one could be responsible for deaths of eagles born near you, wherever your Australian residence may be, is deeply concerning.

Then in an update published yesterday, we heard a response from a Victorian Farmers Federation spokesperson, who made this comment regarding potential unethical situations lambs face if attacked by eagles: "it's not a pleasant death for the lamb, it's fairly horrific." This prompted me to post a video response on my Twitter and Instagram pages to emphasise the point that, if we are talking about animal welfare here, it should be made a much more urgent priority to cull the live export industry, rather than a native predator!!

Although it was published on Tuesday, this update from The Weekly Times only came to my attention this morning. And this quote from it is what grabbed me the most:

"... governments and community needed to do more than just throw up their arms in horror."

I couldn't agree more. What cases like this recent mass-culling event do is highlight that there is clearly a problem (be it perceived or real), and they open a door towards potential growth and change, which is always required to find a solution (it is normally growth in our mindset that is most often necessary).

'We need to either issue farmers with permits to control [eagles], or the community compensates farmers for their (lamb) losses,' Mr Vallance said. 'Farmers are keen to preserve wildlife, but when they come into excess it really does change things.'"

This is one potential solution, but it is short-sighted and does not change the fact that since it was forced onto the Australian landscape, extensive pastoralism centralised around the production of a few species has and always will create all sorts of ecological issues.

As I stated in the Australian Geographic article quoted above:

"What often happens with pastoralism is we simplify ecosystems so every part of the landscape has economic value. We clear land, put sheep in and only focus on keeping animals that benefit us. But we need to focus on biodiversity conservation. This means having a huge diversity of animals in a landscape regardless of their economic value, because the more diverse the ecosystem is, the less likely it is that native predators will kill domestic livestock."

"Retaining large patches of native vegetation that can support a diverse range of animals that offer alternative prey to livestock, such as kangaroos, possums and birds, is one way of solving these problems [and one way of solving many other problems too!]. We simply can't clear all of the land, kill the kangaroos and rabbits, and expect these majestic eagles to eat dust."

A greater understanding of how this continent and its vast assortment of unique, amazing wildlife eats, sleeps, breathes, moves and changes, and a mindset that takes these facts into consideration when deciding what actions we humans take as its current custodians, its clearly what is needed to resolve any/all of the environmental issues that present themselves. Which leads me to my final point, stemming from this quote in The Weekly Times' article:

"... the horrific drought in NSW was likely to be driving Wedge-tailed Eagles off the western plains and on to southern sheep properties [a good ecological explanation and one that is likely, but still speculative without evidence of cause and effect]. 'It’s likely to be a short-term thing for farmers and once they get five inches of rain out on the swamps of NSW they’ll go back where they came from,' Mr Vallance said."

New South Wales and Victoria might be rivals over sporting events or for other anthropocentric reasons, but Australia's ecosystems and their components do not recognise a few lines placed on a map 230 years ago. So the connotations associated with comments about eagles coming from NSW as though they are foreigners invading a state boundary need to be culled. If apex predators did recognise any 'borders' then it would be those created by the land management actions of Aboriginal Australians tens of thousands of years ago, which (mostly through fire) created the diversity of ecosystems that Westerners first saw in 1788. And in order to grow (or 'move forward', as they say in the corporate world!) in the most urgently needed way, we need to turn back the clock, put all our fuel onto the fire of reconciliation with the First Australians, and use the natural history of this country to rebuild the cultural and economic framework that is rapidly weakening.

A bird's eye view gives valuable insights into better ways of custodianship.

Noongar-Martu Cross-cultural meeting

Last June Yirrabiddi, a satellite-tagged Wailitj / Wedge-tailed Eagle who grew up in the same part of the Perth Hills as I did (Parkerville), departed her natal home range and travelled across a vast area of arid Western Australia. In October, after I had completed fieldwork at Matuwa Indigenous Protected Area, this amazing eagle flew in to roost in a tree on the eastern edge of Matuwa, only a few hundred metres from where I had banded an eaglet just days earlier. It seemed this Noongar-Country eagle had travelled all the way to Martu Country, as if by some sort of magic twist she was following me. Below is a collage featuring a picture of Yirrabiddi just before she 'left home', and a map showing her journey between my two PhD study sites.

During last October's on-country fieldwork at Matuwa, Martu elder Rita Cutter made a special wish to one day be able to see "where you grew up, to see your country, Eagleman!", so I knew we had to make this dream come true. Last week this day arrived, and some of the magic is conveyed in the wonderful article by the Hills Gazette's Lynn Grierson that stemmed from this cross-cultural meeting. There was certainly an amazing feeling in the air and I'm looking forward to another day like it very soon!

You can watch a short video of this event, made by budding filmmaker Stella Gray-Broun, by visiting the Vimeo website here.

U3A Armadale

Today I volunteered some time to give one of my 'standard' Wedge-tailed Eagle talks at the meeting of University of the Third Age (U3A) group in Armadale. While talking at the Armadale Library last August, I was pleased to receive a letter from one of the group's members, Keith, kindly inviting me to present at a U3A meeting in 2018. The time went quickly and suddenly today had arrived!

With lots of fieldwork under my belt from the 2018 season there were many updates to share, especially from our recently satellite-tagged eagle Kwidi and her family, and I thoroughly enjoyed meeting some new people and answering their questions. I also really enjoyed the cake and fruit offered for morning tea, and the nice bottle of wine I received as a thank-you for presenting! If you are interested in keeping your mind active, please visit the group's website for more information. Thanks to Keith for setting this occasion up, to all who attended for showing such interest in my research, and especially to Annie taking photos and for her very kind words about my work!
