Image: USGS Science Aids Manatees
November 24, 2017

It may be hard to believe the legend that sailors long-at-sea once considered manatees to be mermaids. The manatee nickname – the “Sea Cow” – which comes from the herbivores’ affinity for grazing on vegetation and their slow, ambling way just makes more sense. But a U.S. Geological Survey video reveals that while they may be cow-like, they also have more than a bit of the magical mermaid to them.

Scavenging birds are at risk of lead poisoning from consuming carcasses of animals killed with lead ammunition. Methods to identify lead exposure typically require capturing an animal to collect a blood sample; however, USGS and U.S. Fish and Wildlife Service researchers sought to design a less costly, noninvasive behavioral test to identify lead exposure in California condors.
