Interspecific differences in developmental mode determine early cognitive abilities in teleost fish
Anim Cogn. 2023 Oct 13. doi: 10.1007/s10071-023-01828-4. Online ahead of print.ABSTRACTMost studies on developmental variation in cognition have suggested that individuals are born with reduced or absent cognitive abilities, and thereafter, cognitive performance increases with age during early development. However, these studies have been mainly performed in altricial species, such as humans, in which offspring are extremely immature at birth. In this work, we tested the hypothesis that species with other developmental modes might show different patterns of cognitive development. To this end, we analysed inhibitory control...

Use of the sun compass by monocularly occluded homing pigeons in a food localisation task in an outdoor arena
Anim Cogn. 2023 Oct 10. doi: 10.1007/s10071-023-01827-5. Online ahead of print.ABSTRACTFunctional asymmetries of the avian visual system can be studied in monocularly occluded birds, as their hemispheres are largely independent. Right and left monocularly occluded homing pigeons and control birds under binocular view have been trained in a food localisation task in an octagonal outdoor arena provided with one coloured beacon on each wall. The three groups were tested after the removal of the visual beacons, so to assess their sun compass learning abilities. Pigeons using the left eye/right hemisphere system exhibited slowe...

"The song remains the same": not really! Vocal flexibility in the song of the indris
In this study, we aimed to quantify the degree of flexibility in the songs of indris (Indri indri), the only singing lemur, using three different metrics: Jaro Distance, normalized diversity, and entropy. We hypothesized that the degree and the co-variation of the flexibility of indris singing together would vary according to their status and sex. We found that dominant females were more flexible than dominant males when concatenating elements into strings (element concatenation). The number of different elements in a song contribution normalized by the contribution length (contribution diversity) of dominant individuals p...

Orientation by environmental geometry and feature cues in the green and black poison frog (Dendrobates auratus)
Anim Cogn. 2023 Sep 12. doi: 10.1007/s10071-023-01820-y. Online ahead of print.ABSTRACTThe ability to use environmental geometry when orienting in space reflects an animal's ability to use a global, allocentric framework. Therefore, understanding when and how animal's use geometry relative to other types of cues in the environment has interested comparative cognition researchers for decades. Yet, only two amphibians have been tested to date. We trained the poison frog Dendrobates auratus to find goal shelters in a rectangular arena, in the presence and absence of a feature cue, and assessed the relative influence of the tw...
