A rare photographic record of the growth of a baby Rufous Owl Ninox rufa, from hatching to independence, in Darwin, Northern Territory Australia.
Meeting other locals is one of the great things about running wildlife tours in remote and regional Australia. On a recce before a Wild Top End tour recently I bumped into a man taking photographs of birds on the East Point Mangrove Boardwalk. We started chatting, realised we had seen each other’s posts on a Northern Territory birds group, and exchanged contact details.
One thing we had in common was a fascination with the pair of Rufous Owls residing near Darwin. That pair had produced a chick, to the great excitement of many tourists and locals.
Over subsequent months that photographer – Christopher Spooner – shared the most delightful series of images of the Rufous Owlet growing up near Darwin. His images are so detailed, and his visits so regular, that he has provided an important record of the growth of this spectactular, rare raptor chick.
In consultation with Christopher, we decided to publish these Rufous Owl images here on this blog, so they can provide a resource for scientific study, wildlife care, interested observers, land managers and anyone active in the care or conservation of this vulnerable tropical owl.
Status of Rufous Owl in Australia
Please contact Christopher if you need more information or use of his images – he is very willing to share them for conservation purposes. Email: firstname.lastname@example.org
The captions on the images are all Christopher’s. I have included some of our images of the baby owl as well, to add to the record.
First sighting: 1 September 2018. Owlet still in nest
Note: Christopher was not looking for a nest, and was just lucky to be there when one of the adults flew to it. He was very cautious not to get close to the nest. He kept this visit time to a minimum and did not return until a week later. It is very important to limit disturbance at nest sites of all birds, especially rare birds like Rufous Owls.
Second sighting: 8 September 2018. Owl chick out of the nest – 54 days old (+/- 4 days)
17 September 2018: Owlet 2 months old (63 days old +/- 4 days) Mother brings a Northern Brushtail prey item.
21 September 2018: Owlet 2 months old (67 days old +/- 4 days) Roosting, stretching with parent
22 September 2018: Owlet 2 months old (images by Echidna Walkabout)
1 October 2018: Owlet 2.6 months old (77 days old +/- 4 days)
8 October 2018: Owlet 2.8 months old (84 days old +/- 4 days)
12 October 2018: Owlet 3 months old (88 days old +/- 4 days)
25 October 2018: Owlet 3.4 months old (101 days old +/- 4 days)
2 November 2018: Owlet 3.6 months old (109 days old +/- 4 days)
26 November 2018: Owlet 4.4 months old (133 days old +/- 4 days)
16 December 2018: Owlet 5 months old (153 days old +/- 4 days)
The contribution that regular citizens can make to conservation of wildlife is profound. The growth of citizen science databases like eBird and iNaturalist have shown the accuracy and breadth of information provided by ordinary people. That data is now heavily used by scientists and land managers.
Please, for the sake of wildlife, take a photo. Publish it somewhere, give a date and a rough location (do not give precise locations of nest sites). You never know how it might help.
Note: be very cautious of taking photographs of nesting birds. Due to bad behaviour by some photographers, photos of nesting birds are banned from many online groups. Read BirdLife Australia’s policy here.
Here’s a list of sites that publish citizen observations of wildlife:
Atlas of Living Australia: All living things in Australia. Photos can be uploaded, best if you know the species.
eBird. All birds worldwide. Single observations can be recorded, best if you know the species. Works on a list system – so you submit a list of all the birds you see in a location.
iNaturalist All living things worldwide. Upload a photo, and even if you have no clue what it is, an expert will check and offer an identification.
Birdline All rare birds, and birds outside of their normal range in Australia. You can – and should if possible – upload a photo. Best if you know the species and know that it is rare or outside its range. A moderator/expert will check, but they are volunteers so best not to trouble them unless you are pretty sure.
Facebook also has many excellent groups that can help with bird identification, rarity, and whether a report should go on Birdline:

Thankyou to Christopher Spooner for taking these images and so generously making them available for the good of the birds.
