Abstract

A pole, extendable from 2 to 8 m, with a nylon-mesh collecting net, was used to retrieve eggs from nests of Great Blue Herons (Ardea herodias) in the canopy of floodplain forests. A total of 200 eggs was collected for contaminant analysis from ten colonies along the upper Mississippi River during the spring of 1993. Low egg breakage (1%) and acceptable survival of embryos in an incubator to pipping (55%) indicated that the device was useful.
