On behalf of the Red-tail Recovery Team and BirdLife Australia I would like to express my sincere thanks to all the volunteers who attended this event. I’d also like to thank all those who reported sightings in the lead up to the count and immediately following. Without volunteer support this event would not be possible.

A very special thanks to Evan Roberts for his ongoing assistance with promoting the count and contacting and encouraging local landholders to search their properties on the day.

Annual Count 2023

Over 120 volunteers participated in this years annual count, held on Saturday 6 May. Volunteers travelled far and wide within the range of the cockatoo in south-east South Australia and south-west Victoria.

After taking into consideration liekly duplicate records and a few additional sightings either side of count day, the final tally stands at 1,204 birds. This is 61 more birds than last year. 

There were 25 sightings across the range on the day even though it was a cold, wet and windy day. The birds were generally found across the middle of the range, with the majority found in the Casterton and Edenhope areas. There were four large flocks sighted, ranging from 120 - 285 birds and a number of smaller flocks with an average size of about 25.

Despite the weather and a few people pulling out, we still had an impressive 65 groups of volunteers, comprising of 128 people. Some volunteers were even able to collect some valuable data on the amount of food currently available for the birds by gathering information on stringybark seed. Sightings of Red-tails proved to be consistent with high scores of stringybark capsules.

This year volunteers teams spent over 257 hours searching for Red-tails, covering more than 2,300 kilometres of roadside stringybark forest. This is a huge effort, especially in not so great weather! The Recovery Team would like to thank all of the volunteers this year. The count would not be possible without everyones help. Its still vitally important that we keep track of the Red-tail population. Having this knowledge allows us to better understand key priorities for conservation methods over time including factors such as habitat use and breeding success.

The day was also finished off with the campout at Baileys Rocks. A small group of volunteers braved the freezing cold weather to sit around a campfire and exchange wonderful stories. Looking forward to that again next year!

A special thankyou also goes to Even Roberts, Bron Perryman, Richard Hill and Tim Burnard for their invaluable annual count knowledge.

Annual Count 2022

This year 70 groups totalling 118 volunteers took part in the annual count. After taking into consideration double counts of cockatoos and a few additional sightings of Red-tails recorded either side of the count day, the final tally stands at 1,143 birds, very close to the 2021 tally of 1,230 birds. 

Volunteers reported 25 sightings this year. The weather conditions on the day were fairly average with many groups experiencing a cold, wet and windy day which may have affected the results. Five large flocks ranging from 70-250 birds were included within the total.

Information gathered during the annual count is crucial to determine patterns of habitat use, the minimum number of birds in the population and most importantly, the location of large flocks. There five large flocks (greater than 70 birds) reported on the day. This year they were found around Edenhope, Coonawarra and Rennick. Other sightings were made near Benayeo, Charam, Langkoop, Derfhol, Penola, Francis and Wandilo.

This year the number of Red-tails observed in Victoria (909 birds and 18 sightings) was greater than that seen in SA (234 birds and 7 sightings). Nineteen groups observed Red-tails wither on count day or within a few days of the count.

We also had the optional stringybark seed monitoring on offer for keen volunteers who wanted to collect additional data for the recovery Project. There were 15 volunteer groups who opted to take part in this, collecting valuable data which will provide important information on food availability for Red-tails.

Some volunteers also attended the Annual Count training session on the morning of the count. this session took place in Rotary Park at Casterton where volunteers learned what the Red-tails sound like, the tell-tale feeding signs and how to identify stringybark from other eucalypt woodland. It was great to meet some of our wonderful volunteers face to face!

This year volunteers spent over 210 hours searching for the cockatoos across the range. participants came from a variety of backgrounds including farmers who searched their own properties, a great team of locals who regularlty take part in the count and several people who travelled from as fas as Adelaide and Melbourne to attend their very first survey.

Annual Count 2021

This year 85 groups totalling 181 volunteers took part in the annual count for the endangered South-eastern Red-tailed Black-Cockatoo across the range on Saturday 1 May.

BirdLife Australia and the SERTBC Recovery Team were thankful that the count was able to go ahead this year, after last year’s backyard birding event which took place instead of the annual count.

After taking into consideration double counts of cockatoos and three additional sightings of Red-tails recorded either side of count day the final tally stands at 1230 birds, slightly more than the 2019 tally of 1193 birds.

Volunteers reported a record number of 57 sightings this year, an increase from the 2019 result of 43 sightings. The weather conditions on the day were fairly mild which resulted in good conditions for counting cockies. Six large flocks ranging in size from 80-200 birds were included within the total.

The birds were again widely dispersed across the range, with sightings from as far north as The Gap in South Australia to Gorae in the south-west of Victoria.

Information gathered during the annual count is crucial to determine patterns of habitat use, the minimum number of birds in the population and most importantly, the location of large flocks. There were six large flocks (greater than 80 birds) reported on the day.

This year, large flocks were found near Edenhope, Langkoop, Coonawarra and Nelson. Other sightings were made near Benayeo, Goroke, Natimuk, Clear Lake, Dergholm, Casterton, Rennick, Digby, Tarpeena and Wattle Range.

The table below provides a breakdown of the results for South Australia and Victoria. This year the number of Red-tails and sightings observed in Victoria (971 birds and 51 sightings/flocks excluding double counts) was greater than that seen in South Australia (259 birds and 6 sightings/flocks excluding double counts).

Thirty-six groups observed Red-tails either on count day or within a few days of the count.

This year there was also optional stringybark seed monitoring on offer for keen volunteers who wanted to collect additional data for the Recovery Project. There were 28 volunteer groups that opted to take part in this monitoring, collecting valuable data which will provide important information on food availability for Red-tails.

A small number of volunteers also attended the Annual Count training session on the morning of the count. This session took place in Rotary Park at Casterton and volunteers learned what the Red-tails sounds like, the tell-tale feeding signs of the birds, and how to identify stringybark from other eucalypt woodland.

This year volunteers spent over 340 hours searching for the cockatoos across their range. Participants came from a variety of different backgrounds including farmers who searched their own properties, a great team of locals who regularly take part in the count, and several participants who travelled from as far as Adelaide and Melbourne to help out with the survey.

'Look to the Skies’ 2020 

This year BirdLife Australia and the South-eastern Red-tailed Black-Cockatoo Recovery Team held a local ‘Look to the Skies’ monitoring event on Saturday 2 May to try and count as many cockies as possible. Due to the COVID-19 restrictions unfortunately we had to cancel our usual Annual Cocky Count, however it is vital at this time of year to count as many Red-tails as we can and find the location of large flocks so we decided to run a smaller event aimed at locals who live in the Red-tail range in south-east SA and south-west Vic.

Participants searched their own properties and backyards for Red-tails on the day and despite the cold and windy weather we received a good number of sightings. The total number of cockies seen on the day was 748 birds from 18 sighting reports, which is a fantastic effort considering most of the birds counted were on private land. Taking into account sighting reports received in the week before and after the event, as well as several large flocks which were known but weren't counted on the day, the number of birds counted came to 1144.

A large number of birds were found in Ullswater, with landholders Ros and Andrew Bradey counting 450 birds on their property and in the surrounding stringybark reserves!

Red-tails were also found in other areas in Victoria including Benayeo and Meereek. In SA birds were found around Naracoorte, Wild Dog Valley, The Gap, Lucindale and Kalangadoo. Other areas where birds had been seen before and after the event included Strathdownie and Clear Lake.

The majority of birds appeared to be in the northern part of the Red-tail range, especially in the Wimmera region. It is likely the birds are taking advantage of the good seed crop currently available for them in Desert stringybark which occurs in that part of the range. While we won't be able to compare the results of this event to previous years' Annual Counts, the data collected is still important in finding the location of large flocks and determining patterns of habitat use.

The following table provides a breakdown of the results for South Australia and Victoria.

*although no birds were counted in the Glenelg Hopkins region on the day, a flock of 156 birds had been sighted in Strathdownie before the event

There were around 40 people who officially registered for the event but it’s likely that more people took part and kept an eye out for Red-tails on the day but didn’t register. The event was promoted widely in the weeks leading up to it and attracted a good amount of attention especially on social media. The Recovery Team has recently set up a new Facebook page for our project, you can find us by searching 'South eastern Red tailed Black Cockatoo Recovery Project'.

The Recovery Team would like to say a massive thank you to everyone who took part in the event and reported sightings, and also to those people who helped promote the event. This would not have been possible without the help and support from locals and landholders in the Red-tail's range. We hope that next year we’ll be able to hold our normal Annual Cocky Count again and volunteers will be able to go out and search for our stunning Red-tails!

Annual Count 2019

This year 81 groups totalling 172 volunteers took part in the annual count for the endangered South-eastern Red-tailed Black-Cockatoo across the range on Saturday 4 May.

The weather conditions improved this year with less wind and rain than the previous few years, which meant that the calls of the cockies were able to be heard more easily. After several years of lower count results it is pleasing to report that the number of birds counted increased considerably this year.

After taking into consideration double counts the final tally stands at 1193 birds, which is substantially higher than last year’s total of 839 birds. Additional sightings either side of the count were also incorporated into the total including a flock of 200 birds, the largest sighting recorded in the count.

The number of sightings reported by volunteers this year was 43, which is slightly less than last year's total of 45.

The distribution of sightings was fairly widespread, with birds again recorded as far north as McCallum (40km NE of Keith). 

There was good weather on the day across most of the range meaning it would have been easier to both see and hear the Red-tails, which may have contributed to the higher number of birds counted this year.

The information gathered during the annual count is crucial to determine patterns of habitat use, the minimum number of birds in the population and most importantly, the location of large flocks. Flock sizes this year were larger than they have been in previous years, with seven large flocks (greater than 80 birds) recorded.

This year, large flocks were found near Edenhope, Penola, Rennick, Dry Creek, Wandilo and Kanawinka. Other sightings were made near Goroke, Harrow, Coonawarra, Dergholm, Nangwarry, Casterton, Nelson, Lucindale, Millicent, Tooan and Frances.

The table below provides a breakdown of the results for South Australia and Victoria. This year the number of Red-tails and sightings observed in Victoria (799 birds and 18 sightings/flocks excluding double counts) was greater than that seen in South Australia (394 birds and 10 sightings/flocks excluding double counts).

Twenty-five groups observed Red-tails either on count day or within a few days of the count.

The annual Baileys Rocks campout was again a success, with volunteers gathering on the night to share stories on how many cockies they saw or the flock that got away.

A total of 10 volunteers also attended the Annual Count training session on the morning of the count. This session took place in Rotary Park at Casterton and volunteers learned what the Red-tails sounds like, the tell-tale feeding signs of the birds, and how to identify stringybark from other eucalypt woodland.

Volunteer effort was fantastic, with 81 groups spending over 270 hours searching for the cockatoos across the range. This year we had volunteers from a variety of different backgrounds including farmers who searched their own properties, a great team of locals who regularly take part in the count, and several participants who travelled from as far as Adelaide and Melbourne to help out with the survey.

Annual Count 2018

This year 89 groups totalling 179 volunteers took part in the annual count for the endangered South-eastern Red-tailed Black-Cockatoo across the range on Saturday 5 May.

Despite the huge search effort, which saw over 3600kms of stringybark forest tracks covered, our cockies proved once again elusive with less than a third of our counters locating Red-tails on the day.

After taking into consideration double counts and two additional sightings of Red-tails recorded on days either side of the count the final tally stands at 839 birds - which is slightly more than the 810 birds recorded last year.

A total of 43 sightings were made on the day, however many of these were double counts of the same birds.

The distribution of sightings was again widespread with one flock seen as far north as McCallum (40km NE of Keith). Flock sizes were also smaller than usual with only four large flocks (greater than 80 birds) recorded. 

Red-tails are notoriously difficult to find. What makes it more challenging is when flock sizes are small, widespread and located in areas that our counters can’t access, such as private land.

Larger flocks are often noisier and so more likely to be detected than smaller flocks, while birds on private land can be easily missed if not for the support of the landholder.

Weather conditions also play a big part in the number of birds counted on the day. This year we experienced less than ideal conditions (wet and windy) in both the lead up to the count and on the day -  across most parts of the range. Windy conditions make hearing birds difficultand let’s face it - you’re more likely to hear a Red-tail before you see one.

Although total numbers are down, it’s unlikely the population has suffered a mass decline since our biggest count of over 1500 birds back in 2015. It’s more likely that birds were scattered widely across their range and simply missed on the day.

The overall prognosis for the population, however, is far from good. Flock counts, which are undertaken after the annual count and provide our best indication of breeding success, have revealed a disturbing trend with declining numbers of females and juveniles recorded in flocks over time.

Fewer adult females means fewer breeding pairs and thus fewer offspring; fewer juveniles means less birds available to replace present breeding pairs in future.

Unfortunately, the last good breeding event was more than 10 years ago. Breeding success is strongly linked to stringybark food availability, with more successful breeding in years of plentiful food.

Counts of large flocks are currently underway based on the information gained through the annual count. Once completed, this will indicate how well the birds bred last season.

This year, large flocks were found near Rennick, Chetwynd, Wattle Range (west of Penola) and Mumbannar. The biggest of these comprised 135 birds drinking from a trough on private land adjacent Rennick State Forest.

Other sightings were made near Harrow, Goroke, Charam, Wandilo, Dry Creek, Dergholm, Lake Mundi, Heywood, Willalooka, Clear Lake, Lucindale, McCallum and Casterton.

Interestingly, many flocks seen this year were found on private land which is why the widespread efforts of landholders to put feeding habitat back on their properties is so important.

The following table provides a breakdown of the results for South Australia and Victoria. This year the number of Red-tails and sightings observed in Victoria (629 birds and 16 sightings/flocks excluding double counts) was greater than that seen in South Australia (210 birds and 13 sightings/flocks excluding double counts).

Twenty-six groups observed Red-tails on count day; with an additional two groups providing sightings of birds (included in the final tally) either side of count day.
