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 …
dr. dolittle | August 23, 2014A new study from researchers at the University of Sydney shows that golden orb-weaving spiders (Nephila plumipes) that live in the city are larger and produce more offspring as compared to country living.
When they say the spiders are big, they mean really big. The females can reach up to 20-25mm (males are only ~5mm).

And while the stories of the Universe I tell you about here don't tend to be my personal, original…
edyong | May 19, 2009While the rapid expansion of human cities has been detrimental for most animals, some have found ways of exploiting these brave new worlds and learned to live with their prolific inhabitants. The Northern mockingbird is one such species. It's very common in cities all over America's east coast, where it frequently spends time around humans. But Douglas Levey from the University of Florida has found that its interactions with us are more complex than anyone would have guessed.
The mockingbird has the remarkable ability to tell the difference between individual humans, regardless of the…
