Pigeons outperform humans when it comes to multitasking

Sara Letzner had humans compete against pigeons in a behavioural experiment. Photo from: Ruhr-Universitat at Bochum A new study conducted by Drs. Sara Letzner and Onur Gunturkun (Ruhr-Universitat at Bochum) as well as Dr. Christian Beste (Technische Univeritat at Dresden) shows that pigeons are better than humans when it comes to multitasking. Their findings were published in Current Biology. The findings from the study show that the mammalian cerebral cortex, with […]

Avian vascular anatomy revealed

This is such a beautiful award-winning image of the complex vascular networks in a pigeon. The image was captured using  CT scan technology and a novel contrasting agent called BriteVu that allows visualization of even tiny capillaries. This image was captured by Scott Echols who is a member of the Grey Parrot Anatomy Project, whose goals are to create technologies to study animal anatomy. The complex capillary network located in […]

Pigeons can identify words

A study recently published in the Proceedings of the National Academy of Sciences provides evidence that pigeons can learn to recognize words. That is after the birds were trained over a period of 8 months. According to the study authors “The pigeons’ performance is actually more comparable to that of literate humans than baboons’ performance.” To read, we must be about to decode letters and the sounds they make as […]

Pigeons in the lead mine?

With reported lead poisonings in cities such as Flint Michigan, methods to detect risk of exposure are desperately needed. Since pigeons live in close proximity to humans, could pigeons be the ‘canary in the lead mine’? Researchers at Columbia University in New York City measured the concentrations of lead in the blood of 825 ill or injured feral pigeons to determine whether the animals could serve as bioindicators of levels in the environment. Their results were published […]
