In the original version of the manuscript, the authors incorrectly interpreted the analysis and data shown in Figure 3B as evidence that males with better memory performance spent less time flying during foraging observations. The correct interpretation is that males with better memory performance spent more time flying while foraging and provisioning offspring. This error does not affect the data, analyses, or main conclusions of the paper. However, on page 1501, we originally speculated that our results suggested that memory facilitates efficient foraging, allowing males to reduce time spent flying. We now offer a possible alternative explanation, namely that males with better memory performance may be exploiting more of their available territory while foraging to provision chicks. As no prior studies have examined the relationship between memory performance and foraging behavior in the wild, we highlighted in our original paper that our suggestion required validation in future studies. This holds true for the alternative hypothesis that we now propose. To correct the interpretation of the result shown in Figure 3B and the associated hypothesis proposed to explain it, in the online version of the paper we have changed one word in the abstract, one word in the figure legend for 3B, and three sentences in the paper. The authors apologize for this error and any confusion that may have resulted and thank the colleagues that brought this to their attention.

Although animal personality research may have applied uses, this suggestion has yet to be evaluated by assessing empirical studies examining animal personality and conservation. To address this knowledge gap, we performed a systematic review of the peer-reviewed literature relating to conservation science and animal personality. Criteria for inclusion in our review included access to full text, primary research articles, and relevant animal conservation or personality focus (i.e., not human personality studies). Ninety-two articles met these criteria. We summarized the conservation contexts, testing procedures (including species and sample size), analytical approach, claimed personality traits (activity, aggression, boldness, exploration, and sociability), and each report's key findings and conservation-focused suggestions. Although providing evidence for repeatability in behavior is crucial for personality studies, repeatability quantification was implemented in only half of the reports. Nonetheless, each of the 5 personality traits were investigated to some extent in a range of conservations contexts. The most robust studies in the field showed variance in how personality relates to other ecologically important variables across species and contexts. Moreover, many studies were first attempts at using personality for conservation purposes in a given study system. Overall, it appears personality is not yet a fully realized tool for conservation. To apply personality research to conservation problems, we suggest researchers think about where individual differences in behavior may affect conservation outcomes in their system, assess where there are opportunities for repeated measures, and follow the most current methodological guides on quantifying personality. KEYWORDS applied animal behavior, behavioral traits, wildlife management ResumenAunque la investigación sobre la personalidad animal puede tener usos aplicados, esta propuesta aún no ha sido evaluada mediante el análisis de estudios empíricos que examinan la personalidad animal y la conservación. Realizamos una revisión sistemática de la literatura revisada por pares relacionada con las ciencias de la conservación y la personalidad animal para abordar este vacío en el conocimiento. Los criterios para la inclusión dentro de nuestra revisión incluyen el acceso al texto completo, artículos de investigación primaria y un enfoque relevante en la conservación animal o en la personalidad (es decir, no estudios sobre la personalidad humana). Noventa y dos artículos cumplieron con estos criterios y de ellos resumimos los contextos de conservación, procedimientos de análisis (incluyendo el tamaño de la muestra y de la especie), estrategia analítica, características declaradas de la personalidad (actividad, agresión, audacia, exploración y sociabilidad) y los hallazgos más importantes de cada reporte y sus sugerencias enfocadas en la conservación. Aunque proporcionar evidencias para la repetitividad en el comportamiento es crucial para los estudiosThis is an open acces...

In many species that have bi-parental care, food-sharing males provide vital nutritional resources to their mates during reproduction. However, it is currently unknown whether females can signal specific desires to their mates, or if males can cater to female desire in the wild. Here we investigate whether and how wild male North Island robins (Petroica longipes) respond to changes in their mates' desires and nutritional need when sharing food. We demonstrate that wild female robins' desire for particular foods changes over short time periods; when given the choice between two types of insect larvae, females prefer the type they have not recently eaten. In our experiments, wild male robins preferentially shared the larvae type that their mate was most likely to desire and also increased the quantity of food shared if she had begun incubating. Males catered to their mates' desire when female behaviour was the only cue available to guide their choices. This is the first evidence that females may behaviourally communicate their specific food desires to their mates, enabling males to cater to fine-scale changes in their mates' nutritional requirements in the wild. Such a simple behaviour-reading mechanism has the potential to be widespread among other food-sharing species.
