Babbler Project awarded an ARC research grant!
December 2021
Very excited to announce that we have won an Australian Research Council grant that will allow us to fund pied babbler research for the next three years! This research will extend PhD student Camilla Soravia's research into the potential impact of heat stress on cognition in wild animals. Since cognition impacts an animal's ability to respond to stimuli in it's surrounding environment, reduced cognition during heat stress may impact their survival through reduced ability to respond to predators, respond to the needs of young, and to invest in adaptive behaviours to find food in high temperatures. The main investigators on this research grant are Amanda Ridley, Ben Ashton and Alex Thornton.

Green Kalahari!
January 2021
La Nina has brought much needed rains to the Kalahari this year, after several years of poor rain. Delightfully, the Kalahari has turned green! And even more spectacular, the Kuruman River is now flowing! This is a very rare event, and the Kuruman River runs right through our study site. It has never flowed through the study site in the whole time since the Babbler Project was established. This year, the flowing water still has not reached the dry riverbed of the study site yet, but we have our fingers crossed that it will!

Western Magpie Project awarded an ARC research grant!
January 2020
Very excited to announce that we have been awarded a three-year research grant by the Australian Research Council to extend our research into the relationship between sociality, cognition and fitness. This research will allow us to conduct experiment to see what causes variation in cognition, and what cognition means in the everyday responses of wild magpies to stimuli such as predators, offspring need, and anthropogenic noise. We aim to see if individuals raised in larger groups receive lifelong benefits of cognition, and if cognition shows plasticity over time. The main investigators on this research project are: Amanda Ridley, Alex Thornton and Ben Ashton.

Another drought year
August 2019
The field site has experienced yet another season of drought. Conditions are now extremely dry following two consecutive drought seasons. The population size (and average group size) is now very low following poor reproductive success for two years. This makes PhD student Camilla Soravia's upcoming field season extra challenging! Fingers crossed for a good rainy season this summer.

New babbler papers at the behaviour-physiology interface
February 2019
It was a great start to the year, with two new papers published at the physiology-behaviour interface! First off was the paper first-authored by PhD student Amanda Bourne, who successfully trialled the efficacy of the non-invasive technique of measuring metabolic rates in wild birds, She did this by collecting pied babbler faecal samples in the 24 hours after feeding them invertebrates injected with doubly labelled water. Her paper appears in Functional Ecology.
The second paper was first-authored by Honours student Emma Jepsen, who successfully trialed a non-invasive technique of monitoring physiological stress, again using faecal samples from the pied babblers in our study population. From this research, she found that dominant males are significantly more stressed than other group members. Her paper appears in General and Comparative Endocrinology. See the Publications page for full details of both papers.

New pied babbler papers hot off the press
May 2018
We have a number of pied babbler papers coming out in 2018, all of which we think present really important findings. For full details of authors and titles, please see the publications tab. First up is the paper by Nelson-Flower et al in Journal of Animal Ecology which tests prevailing hypotheses for the occurrence of cooperative breeding behaviour, and investigates the ecological and social contexts that influence dispersal decisions in pied babblers. Second is the paper by Nelson-Flower et al in Molecular Ecology that looks at factors influencing reproductive skew, and finds different drivers of skew in males versus females. Finally is the paper by Wiley & Ridley in Ecology & Evolution that looks at the pair bond as a predictor of reproductive success and group stability - a factor often overlooked in social species. All three of these papers used the long-term database to elucidate these behavioural trends - emphasising the value of long-term research!

Unexpected babbler babies!
July 2016
After some aseasonal later summer/autumn rains, the babblers have kicked into breeding at a most unusual time for them! New PhD student Amanda Bourne has arrived at the study site to find many new fledglings in the population! We are delighted by the unexpected increase in population numbers, we just have a slight ringing challenge ahead of us (usually babblers are ringed as nestlings)...

Magpie cognition paper in press
January 2016
Our first paper on magpie cognition is now in press for Behavioral Ecology & Sociobiology! To view the paper, please click on the link in the publications tab. This paper is by Honours student (now PhD student) Mel Mirville, and looks at the relationship between group size and performance in an associative learning task. The paper reveals that group size affected neophobia, and hence likelihood to attempt the task. For those that attempted it, adults were much more successful at solving it than juveniles. Once an individual attempted the task, there was no effect of group size on whether the task was solved or not. Well done to Mel for her first paper!

Fully funded PhD on pied babbler research available!
December 2015
We have a fully-funded PhD position based at the Percy Fitzpatrick Institute, University of Cape Town, available. The position will be supervised by me (Amanda Ridley), Claire Spottiswoode and Susie Cunningham. It would involve working with the babblers several months per year at our field site in the remote southern Kalahari, and looks at the effects of group size on thermal tolerance limits, working on the hypothesis that in large groups, where each individual has to do less work, individuals will be better able to tolerate high temperatures. This PhD combine behavioural ecology and physiological research. For more details, see: http://www.hotbirdsproject.com/blog/phd-babblers

Rain, glorious rain
March 2015
It has been a long, hot breeding season, and the rains have come late this year. Finally though, they did come! And now the desert is blooming, with a welcome glut of food for the hungry animals on the reserve. Unfortunately, the rain did not come early enough for another round of breeding attempts before the end of the summer season, so it looks like we have all the babies that we will have this season. A fairly low number of fledglings this year, but still better than some years we have had (still counting the small blessings!).

PhD submitted - congratulations to Oded
November 2014
Congratulations to Oded for submitting his PhD thesis! Oded completed his PhD thesis on individual and group dynamics in the cooperative breeding Arabian babbler. Oded has worked incredibly hard, and has produced a thesis to be proud of. Each thesis submitted represents a huge amount of work by the student, and a lot of love and support from friends and family. Oded and his family are returning back home soon, and they will be sorely missed from the friends they leave behind here in Perth.

New paper accepted!
September 2014
Congrats to Oded Keynan on getting his first paper from his PhD research accepted! Oded's research on free-living, habituated groups of Arabian babblers looks at the acquisition of novel foraging skills, and the causes of variation in this among group members. Oded used experimental cognitive trials to investigate the causes of variation in the acquisition of a novel foraging skill. His paper was accepted today in Behavioral Ecology. TItle: Social foraging strategies and acquisition of a novel foraging skill in a cooperative breeder. By Keynan, O, Ridley, A.R. & Lotem, A. Well done to Oded on a great job, and we look forward to more papers from his exciting PhD research! To the left is a pic of an Arabian babbler flipping lids to access a food reward on the experimental array that Oded used for his research (picture courtesy of Yitzchak Ben Mocha).

First babies of the new breeding season!
August 2014
The first babbler babies of the season have arrived! This is super-early in the breeding season for the babblers, but Lizzy has brought news from the field that RNB have already fledged two young. This is possibly the youngest ever fledglings for a breeding season.

Rain, glorious rain!
January 2013
In contrast to last year, the summer rains arrived this year, and it has made such a dramatic change. The desert is green, flowers are blooming and more importantly, the babblers are breeding! There was a dry spell from Late Dec to mid-Jan, but then the heavens opened again. All the groups are busy building new nests, after most of them had already successfully raised a first clutch in Dec. Several of our groups failed on their first attempts, and so we are hoping this new rain will bring new recruits to their groups. All the adults are in extremely good condition, with high daily body mass measures, and good maintenance off body mass over the chick-rearing period.

New PhD position available
September 2013
Ok, so this PhD is not on babblers, but it is based in my (Mandy Ridley's) research group at UWA! This PhD is based on understanding the reproductive behaviour and foraging ecology of seabirds in the offshore islands of the Browse Basin, north Western Australia. Conditions will be hot, and the study site is very isolated. Deployment of GPS tags to allow remote satellite tracking of individuals will be employed, as well as behavioural observations while on the island. Experience in the handling of birds is a definite advantage, as a number of birds will need to be ringed, tagged, and morphometrics taken on both them, their young, and eggs.

Two new doctors: PhD exams on pied babblers passed with flying colours
August 2013
Warm congratulations to Alex Thompson and David Humphries. Both have now had their PhD theses examined and passed with flying colours: no corrections required for either of them! This is a remarkable achievement and well-deserved after three years of hard slog and dedicated research by them both. Keep your eyes out for chapters of their theses, which are (or already have been) submitted for publication to various journals.
This seems like the appropriate time to acknowledge those hard-working field assistants that helped them both throughout the three years. Although there have been a number of people that have helped (too many to mention, but all greatly appreciated), special mention goes to Fiona Finch, who tirelessly helped both Dave and Alex over a three year period and worked wonderfully with the babblers. Also Adam Britton, who put a long summer field season in for Alex, and always did his fieldwork with a smile.

New paper: the ecological benefits of interceptive eavesdropping
July 2013
We have recently had a paper accepted into Functional Ecology. In this paper we look at the interspecific interaction between pied babblers and the solitarily foraging scimitarbill. We find that scimitarbills, who not have a reliable vigilance system of their own, regularly follow babbler groups and eavesdrop on the predator information that babbler sentinels provide. By so doing, scimitarbills gain significant benefits - they spend less time vigilant, more time foraging, and can utilise a greater diversity of foraging habitats than when alone.

The influence of siblings on begging behaviour - a new paper accepted
July 2013
We have recently had a paper accepted into Animal Behaviour. In this paper we test the three hypotheses for the occurrence of begging behaviours when there are broodmates around: cooperative begging, competitive begging, or begging simply as an honest signal of hunger. We use experiments and observations to conclude that begging is simply an honest signal of need by chicks, with no evidence that broodmates try to outcompete one another with their begging calls in order to attract more food from parents. Title: The influence of siblings on begging behaviour. Authors: Thompson, A.M., Ridley, A.R., Hockey, P.A.R., Finch, F.M., Britton, A. & Raihani, N.J.

The cost of female competition on group productivity - a new paper accepted
May 2013
We have recently had a paper accepted into Proceedings B! In this manuscript we look at evidence for female competition within groups, and ask what impact this has on reproductive success. We find evidence for costly female competition in the form of infanticide (females eat their competitor's eggs to prevent them from breeding) and nest abandonment. Such competition can delay breeding for several months, and results in reduced reproductive output for groups containing competing females. Importantly, these behavioural results reveal that there is considerable competition between females, even though molecular parentage data reveal little evidence for such competition. This is because females actively compete prior to a clutch being produced. Title: Costly reproductive competition between females in a monogamous cooperatively breeding bird.

Can offspring blackmail their parents into feeding them more? A new paper accepted
March 2013
We have recently had a paper accepted into Proceedings B. In this manuscript we test Zahavi's blackmail hypothesis, and find evidence that fledglings can manipulate adults into feeding them more by the threat of their own destruction. Fledglings achieve this by strategically begging in dangerous locations when adult feeding rate is low, promoting adults to feed them at a higher rate. This is one of the first empirical examples to provide evidence for Zahavi's blackmail hypothesis.

The worst drought the Project has ever experienced
February 2013
Another breeding season has ended, but the tragedy this season was that it never really started. It was a scorching summer in the Kalahari, but sadly for the animals, the rains never came. Day after day of searing heat, but no rain respite made it the worst ever breeding season for the pied babblers. With very little food around, most groups did not bother to make any breeding attempts after December (which was when the rains SHOULD have arrived). Currently, we have only eight fledglings in the entire population. More groups did fledge young, but these have since been predated. Seven of our groups have gone extinct, and with a harsh winter coming up, we expect more extinctions before the next breeding season starts. While this is a very sad event for us all at Babbler Project, on the bright side it is very interesting demographically, which helps us with the aims of our recent successful research grant!

The youngest member of our research team!February 2013
Kito came out with us several times when we were doing brief life history checks on some of our groups. Here he is pictured with MPOR, natal to the group Duty Free, but now the dominant female at STT. This group lost their helper and tried to raise a baby only as a pair during an extreme drought. No other group in the population was breeding. Surprisingly, they fledged one chick. They lost incredible amounts of body mass during this breeding attempt. Ultimately, their valiant efforts were for nought, with their small fledgling being predated at only one week old. Kito found these two hard-working parents fascinating, and enjoyed watching them. Because of Kito's small size (compared to other babbler researchers!), the babblers are very relaxed around him. |
A new baby!

More rain in the Arava
January 2013
With the THIRD flood of the season, it is safe to say that the drought has truly broken at the Arabian Babbler Project. This is fantastic news, after many years of poor rain and low breeding success, this bodes well for a bumper breeding season in 2013. Fingers crossed!

Flash floods in the Arava!November 2012
Finally some welcome rains have fallen at the Arabian Babbler study site! After a very poor and very dry breeding season, flash floods have hit the Arava. While these can be very dangerous in the short-term while they flow through the bone-dry river channels, they bring much needed water to a parched ecosystem, and are followed soon after by abundant germination. The picture to the right is a flash flood flowing along a wadi (river channel) that was previously completely dry. |

The re-occurrence of an extraordinary behaviour: a new kidnapping event in the population
November 2012
The big news from Lizzy is that there is a new kidnapping event in the population! This is EXTREMELY interesting for us. Kidnapping is a rare behaviour, but entirely unexpected, and happens far more often than we would have ever imagined. This kidnapping fits the profile: CMF, a very small group who have failed to raise their own young for one and a half years (and are therefore at high risk of extinction), have stolen one of SHA group's very young fledglings. They are looking after it as if it was their own. We will continue to monitor this intriguing relationship between kidnapper and kidnapee.

First babbler babies of the southern season
November 2012
It has been a delayed start of the breeding season this year, perhaps because of the continuing low temperatures, and our first babies of the season have only just arrived. Three large nestlings were ringed in the group Duty Free on Saturday the 10th. Interestingly , DTF were the first to breed last year as well. A further nine nests hatched onsite this weekend, so hopefully lots more babies coming soon!

Are sentinels safe? A new babbler paper accepted
October 2012
We have recently had a paper accepted to the journal Animal Behaviour. This paper tests the two different hypotheses of sentinel behaviour - cooperative vs selfish. We refute the hypothesis that sentinels are safe and selfish, by showing that (a) they are further from cover than foragers, (b) take longer to reach cover following an alarm call and (c) are more likely to be targeted for attack during a predator strike. The paper provides the first experimental evidence for the cooperative hypothesis of sentinel behaviour. Title: Is sentinel behaviour safe? An experimental investigation.

Sad news for the start of the breeding season
October 2012
Lizzy reports the sad news that one of our oldest babblers, TMBY, has gone. TMBY had been the dominant male of group OSD for over nine years. He was of unknown age, since he was already the dominant male when I first began working with OSD in 2003. He was an incredibly successful male, having fathered many young that have since gone on to become dominant breeding individuals in other groups within the study population. TMBY was also extremely useful in the habituation process - being an unusually friendly dominant male the rest of the group followed his lead and responded very well to observer presence from very early on. TMBY will be sorely missed, but leaves an unforgettable bunch of charismatic offspring behind.

A new babbler paper on social foraging behaviour
October 2012
We have had a new paper accepted for publication. This paper, led by Alex Thompson, looks at the social foraging behaviour of fledglings. Alex found that fledglings do not just follow any adult to solicit food, but prefer to follow adults with high foraging success, since they are more likely to receive food from these adults. An experiment revealed that fledglings can change their social foraging behaviour very quickly following an artificial elevation in adult foraging success. This work suggests that fledglings monitor adults closely in order to maximise the benefits of social foraging behaviour. This research will be published in the journal Behavioral Ecology and Sociobiology. Congratulations to Alex on his first primary author publication! Title: Do fledglings choose wisely? An experimental investigation into social foraging behaviour. Thompson, A.M. & Ridley, A.R.

The loss of a matriarch
September 2012
It is with sadness that I announce the loss of a matriarch to the population, BMBO. Originally from Rainbow (one of our first ever habituated groups), BMBO dispersed and founded her own group. Her dispersal record remains the furthest that we have ever recorded a babbler dispersing within our study population. She founded the group called Ngai Tahu, and remained dominant from the start of the group three years ago until her recent disappearance. She is succeeded by her three daughters, one of whom may take the dominant female position (she is unrelated to the current dominant male).

A poor breeding season for the Arabian babblers
August 2012
Unfortunately, despite our high hopes, the drought in the Negev Desert resulted in a very poor breeding season for the Arabian babbler population. Although Oded recorded a surprising amount of breeding activity given the dry conditions, very few of these young survived long enough to recruit to the adult population. There are now only a handful of juveniles around from the season's breeding activity, who face the struggle of making it through a difficult winter with little food around.

An old matriarch returns to the population
July 2012
An update on a previous post regarding a new dominant female at XHOSA group: the new female turns out to be one of our old matriarchs - OMRY (now with only a numbered metal ring, hence the delay in positively identifying her). OMRY was born in SOX's group in 2005, dispersed to Infidels after her sister died while incubating a brood, and then struggled for several years with the dominant male (YMPY) to raise young as a pair. Last year OMRY left the population (replaced at Infidels by a new dominant female from Sundowners) and was found again several months later in a peripheral group in marginal habitat, where she succeeded in raising several broods. We are however delighted that she has now returned to the main population and we hope to be able to monitor her reign as the dominant female of a new group for many years to come.

Two new drongo-babbler papers!
July 2012
We have had two new papers accepted for publication. The first (published in Animal Behaviour) represents research done by Matt Child when he was my Hons student . This research looks at how differences in beak morphology between drongos and babblers may have catalysed the targeting of babblers by the kleptoparasitic drongo for food sources (subterranean prey) that they are unable to excavate themselves. The second, led by Dr Tom Flower, looks at the ecological economics of kleptoparasitism by the drongo, and suggests that the changes in ecological conditions that affect the profitability of kelptoparasitism may be the reason why drongos use this foraging strategy on a facultative basis (i.e. they forage for themselves when the benefits from kleptoparasitism are low, and vice versa). This manuscript is in press at the Journal of Animal Ecology. As mentioned in the "Photo gallery' page my research on drongos has wound down and is now being prinicipally lead by my collaborator Dr Tom Flower. For more info on Tom and his research, click here.

Another immigrant dominant female
June 2012
Following the drowning of CGMX, the dominant female from Xhosa group (XHO), she has been replaced by a wild female from outside our study population. This makes two new dominant females so far this winter season, and a lot of habituation work for us! Unfortunately, the death of all three fledglings from CGMX's last brood has also been confirmed, bringing Xhosa's group size down to four adults and two juveniles.

Breeding in full swing in the Shezaf Nature Reserve
June 2012
Happily, after a slow start to the season due to dry conditions, breeding is now in full swing. Oded has reported that a number of groups are breeding - while some are still on eggs, others now have young fledglings. The 'miracle' brood of seven has unfortunately been reduced to one remaining fledgling - perhaps the sound of so many hungrily begging chicks attracted predators to the brood. Maybe this loss will promote the group to breed again and produce another enormous brood?

Winter is always a tough time for the pied babblers - a time when group composition changes dramatically due not only to mortality, but also to reproductive conflict and dispersal attempts prior to the breeding season. Recently CGMX, the dominant female of Xhosa group, was found drowned in one of the dams at our study site. During the dry winter season the babblers are unfortunately drawn to these man-made dams in search of water. Her youngest brood is also missing, but we hope that they are found elsewhere. The dominant female of Catlaughers, TTOM, has been evicted (along with one of her offspring) by an unringed female who has now taken the dominant position. Tom (Flower) reports seeing TTOM and her young attempting to return to the group, but she was successfully chased away by the new dominant female. Surprisingly, the mortality count for the winter season has thus far been lower than expected.

A new babbler paper accepted
June 2012
We have recently had a manuscript accepted to Global Change Biology. This manuscript, based on the MSc fieldwork of Kate du Plessis, looks at the behavioural and body mass changes in pied babblers according to changes in temperature - the main focus of the paper is to investigate the potential (sub-lethal) effects of increasing temperature (under predicted climate change) on bird populations in semi-arid zones. Congrats to the whole team (Kate was supervised by myself, Phil Hockey Rowan Martin & Susie Cunningham)! Link

Seven chicks in one nest!
June 2012
Oded & Zach bring the exciting news of having recently ringed seven chicks in one nest!! Since typical brood size is 2-4 nestlings, this brood size is exceptional, and suggests that more than one female laid eggs. Oded reports seeing the dominant male mate with two females in the group. We look forward to finding out if all seven nestlings survive! With another group having recently fledged four young, it is great to see some breeding going on in a very dry year at Hatzeva.

A harsh winter making it tough for the pied babblers
June 2012
On the back of a dry summer with limited insect emergence, has come a very cold winter in the Kalahari. Tom, a research collaborator currently onsite working on drongo-babbler interactions, has reported that the babblers are suffering badly from the harsh combination of cold weather and limited food. Many are steadily losing weight, and at this rate we can expect that some of our juveniles will not make it through their first winter. Fingers crossed the toll will not be too high.

Another new researcher joins the group
May 2012
Congratulations to Sabrina Engesser, who will also be joining the pied babbler research team this breeding season. Sabrina won a PhD scholarship to Zurich University. We are delighted to have two new researchers join the pied babbler team (James & Sabrina), especially since Dave Humphries and Alex Thompson finished the fieldwork component of their PhDs this April!

Drought hits the babblers
April 2012
Unfortunately this year both our research populations have been hit by drought. In South Africa the summer has now ended and after low rainfall over the rainy season pied babbler breeding success was very low. Several of our groups failed to raise any young. Our outstanding performers for the year were group Xhosa, who bucked the trend and managed to raise five young to independence.
In Israel the breeding season is a few months in, and it is extremely dry (Oded reports only 7 mm of rain so far). Many groups are still not breeding and it does not look like a promising breeding season. Oded (currently in-field) brings happy news that one group currently has nestlings, and two groups have managed to fledge young - we'll cross our fingers that their fledglings manage to keep healthy.
