Description
Abstract. -- This east Texas study was undertaken to determine the importance of seeds of forbs, grasses, and woody shrubs to songbirds wintering in young pine plantations which had been established utilizing the clearcut regeneration system. The feeding habits and preferences of four species of songbirds, northern cardinals (Cardinalis cardinalis), song sparrows (Melospiza melodia), dark-eyed juncos (Junco hyemalis), and white-throated sparrows (Zonotrichia albicollis) were examined from November to February of 1980-81, 1981-82, and 1982-83. Differences in consumption percentages were compared among bird species using ANOVA and Duncan's multiple range tests. Paired t-tests were used to compare seeds consumed to seeds available by bird species. Differences (P [less than or equal to] 0.05) existed among bird species in consumption percentages of seeds of various genera. Northern cardinals selected seeds of Callicarpa, Croton, Datura, and Galactia. Song sparrows used seeds of Ambrosia, Panicum, and Seteria in excess of abundance. Dark-eyed juncos also selected Ambrosia as well as Eragrostis and Parietaria over seeds of other genera. Ambrosia, Parietaria, Aristida, and Viola were preferred by white-throated sparrows. **********
