Abstract

Recent attempts to explain the decline of many Loggerhead Shrike (Lanius ludovicianus) populations (Bystrak and Robbins 1977, Geissler and Noon 198 I, Morrison I98 I) have focused on habitat loss due to modem agricultural practices (Brooks and Temple 1990; Smith and Kruse 1992; Yosefand Grubb 1992,1993; Gawlik and Bildstein 1993). Degree of habitat loss is consistent with the differential declines of shrike populations observed in various regions of the United States. Populations in the intensive agricultural areas of the midwest, south, and southeast are declining more severely than those in the western United States dominated by grasslands (Arbib 1977, Morrison 1981). Although a considerable amount of information exists on shrikes in agricultural systems, none is available regarding habitat changes and the mechanisms affecting shrikes in natural grasslands. Understanding shrike use of natural grasslands can lead to a better understanding of shrike response to land-use changes.
