Cognitive control of memory in a food-storing and a non-storing bird species

Emily Kathryn Brown, David Francis Sherry, Robert R. Hampton

Scatter hoarding black-capped chickadees use memory to relocate hidden food, often after delays of hours or days. The ability of these birds to maintain accurate memories of the location and current status of many food caches while engaging in other distracting daily …

Brood-parasitic female cowbirds have better numerical abilities than males on a task resembling nest prospecting behaviour

Mélanie F. Guigueno, Marco Alexander Coto, David Francis Sherry

Selection can act in a sex-specific manner on cognitive abilities, including numerosity, especially when ecological roles differ between sexes. However, few systems exist in which numerical abilities would be expected to differ between the sexes, and even fewer focus on systems in …

On the atmospheric budget of 1,2-dichloroethane and its impact on stratospheric chlorine and ozone (2002–2020)

Ryan Hossaini, David Francis Sherry, Zihao Wang, Martyn P. Chipperfield et autres

The chemical compound 1,2-dichloroethane (DCE), or ethylene dichloride, is an industrial very short-lived substance (VSLS) whose major use is as a feedstock in the production chain of polyvinyl chloride (PVC). Like other chlorinated VSLSs, transport of DCE (and/or its atmospheric oxidation products) …

Food Storing by Mexican Chickadees and Bridled Titmice

Robert R. Hampton, David Francis Sherry

Food storing is widespread but not universal in the Paridae. Worldwide, 14 species are known to store food (Sherry 1989). Two species, the Great Tit (Parus major) and the Blue Tit (P. caeruleus), are known not to store, or to do so …

Molecular Changes in the Brain of the Wintering Calidris pusilla in the Mangroves of the Amazon River Estuary

Patrick Douglas Côrrea Pereira, Ediely Pereira Henrique, Emanuel Ramos da Costa, Anderson de Jesus Falcão et autres

Migrant birds prepare differently to fly north for breeding in the spring and for the flight to lower latitudes during autumn, avoiding the cold and food shortages of the Northern Hemisphere’s harsh winter. The molecular events associated with these fundamental stages in …

Neuronal activation in the geomagnetic responsive region Cluster N covaries with nocturnal migratory restlessness in white‐throated sparrows ( Zonotrichia albicollis )

Madeleine I. R. Brodbeck, Verner Peter Bingman, Lauren J. Cole, David Francis Sherry et autres

Cluster N is a region of the visual forebrain of nocturnally migrating songbirds that supports the geomagnetic compass of nocturnal migrants. Cluster N expresses immediate-early genes (ZENK), indicating neuronal activation. This neuronal activity has only been recorded at night during the migratory …

Supplementary Material for: Risk Factors of Progression to Cognitive Frailty: Singapore Longitudinal Ageing Study 2

David Francis Sherry, Gustavo Jabor Gozzi, Amanda do Rocio Andrade Pires, Mike B. Calford et autres

Introduction: Cognitive frailty is associated with higher risk of dementia and adverse health outcomes. However, multidimensional factors that influence cognitive frailty transitions are not known. We aim to investigate risk factors of incident cognitive frailty. Methods: Prospective cohort study participants were community-dwelling …
