1 The number of stomachs recorded here often exceeds the number used in tabulating food percentages 
as recorded in the text, because a portion of the stomachs examined did not contain sufficient food for the 
estimation of percentages but did yield data concerning food items. The food items of the black-whiskered 
vireo (4 stomachs) (see pp. 3-4) and of the gray vireo (2 stomachs) (see p. 27) have not been included in 
the tabulation.
