During the Sonoran Desert summer, saguaro cacti produce an abundant fruit crop whose nutrients and water have distinctive stable isotope compositions. Carbon stable isotope analyses indicated that, at the peak of saguaro fruit production, saguaro fruit represented .90% of White-winged Dove and ;50% of Mourning Dove carbon incorporation. Over the entire summer, saguaro fruit comprised 50% and 14...

Given the latter's penchant for the intrapsychic view, the perspective on mourning has become reduced to the individual. These trends are clearly reflected i...

We examined the predatory behavior of wintering urban Cooper’s Hawks (Accipiter cooperii). Eight Cooper’s Hawks (7 female, 1 male) were radio-tracked intensively during two winter periods from 1999–2001. We observed 179 attacks, 35 of which were successful, for an overall attack success rate of 20%. We recorded an additional 44 kills resulting from unobserved attacks. European Starlings (Sturnu...
