More than ruffled feathers: Mockingbirds show heightened aggression after lead exposure

(Morris Animal Foundation) Mockingbirds exposed to sub-lethal levels of lead in urban areas display significantly heightened aggression, said Morris Animal Foundation-funded researchers at Tulane University. The team said their findings highlight the possibility that sub-lethal lead exposure may be common among other wildlife living in urban areas and more work is needed to better understand its full effects. Their study was published in Science of the Total Environment.
