Males carried mainly dry twigs during the pre-laying period; females carried mostly leafy twigs usually after laying. Brooding is carried out almost entirely by the females (83 vs 17%), and females alone were observed to brood during the night. The adults’ behaviour differed even further during the fledging period: the male went hunting and limited himself almost exclusively to delivering the prey, while the female continued to remain at the nest until the chick was 22 days old, after which her absences increased constantly up to the 45th day, which is more than half of the fledging period. Female-chick interactions can be frequent and lasts up to the middle of the fledging period. Significant behavioural differences emerged from the comparison between the two pairs during the pre-laying period: in particular the average daily presence at the nest (72 vs 31 min) and the number of prey items offered at the nest by the male (29 vs 4). We also observed evident differences between pairs in the nest courtship displays. In one nest we observed an unmistakable and frequent behaviour, that we propose to call “neck display”, and which was never observed in the other nest.","PeriodicalId":230805,"journal":{"name":"Ethology Ecology & Evolution","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115367669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eleonora’s falcon is an iconic, long-distance migrant bird of the Palearctic region. While various aspects of its life history have been thoroughly studied, its dependence on water sources has been poorly documented. In this study, we examine for the first time the species’ visitation patterns at a complex of small, natural ponds of karstic water on a Greek island and provide a detailed description of its bathing and drinking behaviour using visual observations and camera traps. Our results indicate that the species visits the ponds systematically from spring until autumn to bathe and drink. Water visitation patterns suggest communal behaviour, most probably benefitting from increased vigilance in greater numbers. In spring, male falcons prevail during water sessions and the reverse pattern is observed in autumn, whereas morph ratio remains stable, close to the expected 3:1 ratio. Temperature, affecting the falcons’ foraging activity and/or their heat dissipation requirements, together with seasonal differences in labour division between sexes can explain a significant amount of the observed variability in water visitation patterns. Freshwater sources in most islets hosting breeding colonies are scarce, thus natural ponds in nearby larger islands are an important resource many falcons could rely on while at their breeding grounds. The identification and preservation of bathing and drinking spots where falcons gather in numbers across its breeding range is thus highly recommended. Considering the forecasted impact of climate change on karstic water we also encourage an in-depth analysis of the role of water in the adaptation of Eleonora’s falcon to a life in insular environments experiencing global warming. Last but not least, further investigation of the species’ communal behaviour regarding water use can also offer interesting insights in the species’ natural history.

Birds that have been claimed to show this ability are all corvids. In this study, we conducted a series of mirror-related tests, including open mirror exposure, mirror-mediated foraging task and mark test, to investigate this ability in the African grey parrot. Subjects responded to the mirror on three levels. Three subjects consistently showed social behaviours towards the mirror, two of which repeatedly hit the mirror throughout the test, indicating a complete lack of mirror perception and self-recognition. Two subjects showed social behaviours or hit the mirror almost within the first 10 min of the mirror trial, indicating they initially recognized mirror images as conspecifics but changed this misconception over time. There was only one individual, who not only never hit the mirror and exhibited social behaviours towards the mirror, but also could use the mirror to locate hidden food and mark on the body that was invisible without a mirror. However, considering the lack of contingent behaviours and spontaneous mirror-guided self-directed behaviours, it is hard to assert the African grey parrot possesses mirror self-recognition. All in all, we found our subjects responded differently towards the mirror, showing varying levels of understanding of the mirror. Our findings support the gradualist perspective on mirror self-recognition. Different mark methods are also discussed, and we suggest attaching the mark on the mandible in future parrot research.

One subject found hidden food as soon as a mirror was presented.

For the experiment, we used six aquariums divided into three treatment groups: white background; black background; red background; with two replicates for each group.

We used ImageJ software to obtain the RGB values (Red, Green, Blue) of the dorsal region of the first abdominal somite of the shrimps. Before the experiment, the body pigmentation of M. jelskii was homogeneous, with overlap between the groups. After the experiment, the RGB of M. jelskii varied according to each background colour, differing between the white and black, between the white and red, and not differing between the black and red.

Juvenile lizards are subject to the same ecological pressures, but may additionally experience predation or exclusion from prime basking site by adults and hence their capacity to achieve preferred body temperatures. In this paper, we examined basking site selection in juvenile western green lizards, Lacerta bilineata and compared them to basking site availability. Secondly, measurements of morning substrate temperatures at different basking sites were compared to basking site selection over the same period. The results indicated that juveniles selected substrates with fast heating surfaces, for example fallen branches for basking, in greater frequency than their availability but in even greater than expected frequency on the cooler surfaces of clusters of bramble plant. This finding contrasted with basking site selection in adult L. bilineata in a previous study where wood surfaces was preferred over non-wood surfaces whilst avoiding basking on bramble. This illustrates the different ecological requirements between adults and juveniles.","PeriodicalId":230805,"journal":{"name":"Ethology Ecology & Evolution","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115718206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
