abstract

Competitive interactions between Red-winged (Agelaius phoeniceus) and Yellow-headedblackbirds (Xanthocephalus xathocephalus) have been reported by a number of workers(e.g., Orians and Willson 1964, Willson 1966, Miller 1968). Most studies concerned withboth species occurring together have been conductedin western regions of North America;however, see Weller and Spatcher (1965), Burt (1970), and Voights (1973) for accountsof the two speciesin Iowa marshes.
