TL;DR: In this paper, the authors evaluated whether an early postnatal infection poses a long-term risk for neuropsychological impairment to neonates born very prematurely and found that adolescents born very preterm had significantly lower scores than term born controls on IQ (preterm: mean [SD] −98.43 [14.83], control: 110.00 [8.10], P ǫ=−.015) and on visuoperceptive abilities (95.64 [12.87] vs 106.24 [9.95] vs 102.75 [13

TL;DR: It is shown that crows, songbirds of the corvid family, can be trained to exert control over their vocalizations, suggesting that songbird vocalizations are under cognitive control and can be decoupled from affective states.

TL;DR: Observers pilfered according to their current desire and cachers protected their caches by selectively caching food that observers were not motivated to pilfer: the same cache-protection behaviour was found when cachers could not see on which food the observers were sated.

TL;DR: This study presents 12 carrion crows with the mirror mark test and concludes that their crows fail the test, and thereby replicate previous studies showing a similar failure in corvids, and crows in particular.

TL;DR: In this article, the authors identify the socio-ecological correlates of neophobia in corvids and grant insight into specific elements that drive higher neophobic responses in this avian family group.
