🧪 ETHOLOGY: What keeps animal societies together? 🐘🐒🐺🦜 Kappeler reviews how animal groups form, stay cohesive, and maintain social order. Beyond the benefits of group living, behavioral mechanisms may reduce conflict and promote stable, cooperative societies. #OpenAccess doi.org/10.1111/eth....

From Cohesion to Norms: How Animal Groups Come, Stay, and Function Together

The present review underscores two salient points: In the context of evolutionary transitions to pair- and group living, it is imperative to acknowledge the distinction between selective forces that ...

🧪 ETHOLOGY: Peep, squeal and claim! 🐸📢🌿 Turin & Nali found that male torrent frogs use a surprisingly complex repertoire of territorial calls. Calls vary with social context and temperature—but unlike advertisement calls, they are not shaped by stream noise. #OpenAccess: doi.org/10.1111/eth.70086

Peep, Squeal and Claim: Complex Territorial Call Emission Across Social Contexts in a Neotropical Torrent Frog

Males of Hylodes perere emit territorial calls ranging from simple to complex combinations of peep (A) and squeal (B) notes, often accompanied by visual signals. Because note A resembles advertisemen....

🧪 ETHOLOGY: Are early birds also early breeders? 🐦⏰🥚 Elderbrock et al. found that female great tits that started their day earlier before breeding also laid eggs earlier in the season. Daily rhythms and seasonal timing appear to be linked. #OpenAccess: doi.org/10.1111/eth.70089

Chronotype and Seasonal Timing of Reproduction Are Related in a Female Songbird

In this study we found evidence that seasonal timing of reproduction is related to timing of daily activity in great tits (Parus major). Female birds who began daily activity earlier relative to sunr...

🧪 ETHOLOGY: Do helpers reduce parental workload? 🐦🤝 Koenig & Walters show that the answer depends on the analysis. Acorn woodpeckers feed less overall in larger groups, but during short observations they match the feeding rates of others. Scale matters! #OpenAccess: doi.org/10.1111/eth.70087

Load Lightening in the Cooperatively Breeding Acorn Woodpecker Depends on the Analysis

An illustration of load lightening, additive, and compensatory care. The cooperatively breeding acorn woodpecker exhibits load lightening when analyzed by group size over the course of a breeding eff...

The effect of parental provisioning on the development of prey preferences in great tit (Parus major) bioRxivpreprint

The effect of parental provisioning on the development of prey preferences in great tit (Parus major)

To make adaptive foraging decisions, naive individuals need to gather information about the local prey community. Besides sampling prey personally, the young could gather information about prey profitability by observing the foraging behaviour of other individuals, and parental provisioning provides the first opportunity to acquire this social information. Still, previous research on vertical transmission of prey preferences from parents has provided mixed results that are often confounded with other information sources, such as siblings and peers. It is also not known whether information from parents can change potential innate biases against certain prey types, such as avoidance of warningly coloured insects. Here, we tested whether social information acquired by offspring during parental provisioning influences the development of prey preferences in a generalist predator, the Great Tit (Parus major). We brought 15 great tit broods and their parents into captivity at late nestling stage (14 days old) and divided them into three social information treatments where parents were provided with either brown, red or yellow palatable maggots to feed to their dependent young for 8 days. Once foraging independently from parents, we conducted a preference test where juveniles were offered the full array of coloured maggots. Regardless of palatable exposure to typical warning-coloured maggots (i.e. red and yellow), juveniles consistently preferred yellow over red, and preferred brown maggots the most (i.e. lacking warning coloration). This supports the existence of innate biases against typical warning colours, and that social information from parents is unlikely to override these, at least when alternative prey is easily available.

🧪 ETHOLOGY: Female scorpions are the louder defenders! 🦂🔊 Dionisio-da-Silva et al. show that female scorpions produce longer and louder stridulatory signals than males. Sex-specific differences shape these signals, supporting stridulation as antipredator defense. #OpenAccess doi.org/10.1111/eth....

She Doesn't Whisper: Female‐Prominent Stridulation Shaped by Morphology in a Buthid Scorpion and Insights on Its Function

Sexual dimorphism and stress-induced stridulatory responses in Jaguajir rochae (Borelli, 1910). Females exhibited greater absolute pectinal size and higher sound pressure levels, whereas males showed...
