Which pesticide, formerly used for insect control in the United States, is known to cause eggshell thinning among eagles, pelicans, and other birds?

DDT has been shown to have adverse effects in both humans and animals. Although it's only deemed slightly to moderately toxic when ingested by birds, the chemicals disturb calcium levels, leading to thinner eggshells and embryo deaths.
