Nesting association of Least Bitterns and Boat-tailed Grackles

Article Abstract:

The nesting associations of Least Bitterns and Boat-tailed Grackels were investigated. The study was made from 1985 to 1991 in a 30-hectare cattail marsh at Magnolia Gardens in South Carolina. The vegetation density, vegetation heterogeneity andnest site characteristics were examined. The height of the birds' eggs above water was also measured. Results were found to suppport the hypothesis that Least Bitterns associate actively with Boat-tailed Grackles.

Video documentation of a Brown-headed Cowbird nestling ejecting an Indigo Bunting nestling from the nest

Article Abstract:

A video recording of nests of Indigo Buntings near Ashland reveals that Brown-headed Cowbird nestlings can eject the host Indigo Bunting nestlings from the nest. The Indigo Buntings nestlings in parasitized nests show depressed growth during the nestling period. However, they rapidly gain weight during the last few days in the nest. These nestlings frequently attain the weight comparable to that of chicks from unparasitized nests.

Impact of brood parasitism on nest survival parameters and seasonal fecundity of six songbird species in SouthEastern Old-Field habitat

Article Abstract:

Issues concerning the rates of parasitism and nest predation rates in Brown-headed Cowbird in James Island in South Carolina, United States, are discussed. Particular attention is given to fecundity implications of nest predation and brood parasitism.
