White-tailed deer (odocoileus virginianus) were videotaped depredating four songbird nests in grassland habitats in southeastern and northcentral North Dakota, 1996-1999. Deer ate two Savannah sparrow (Passerculus sandwichensis), two grasshopper sparrow (Ammodramus savannarum), one clay-colored sparrow (Spizella pallida), one red-winged blackbird (Agelaius phoeniceus) and three brown-headed cowbird (Molothrus ater) nestlings. Deer removed nestlings quickly (5-19 sec/nest) at night (22:00 to 05:17 Central Daylight Time) and left no evidence of predation. Although probably opportunistic, deer predations clearly were deliberate and likely are more common than generally believed.

... Tropical deer species can be voracious consumers of both fruits and seeds (Harrison et al., 2013;Sridhara et al., 2016), playing important roles in seed dispersal and seed predation in landscapes that are adequately protected from poaching (Bodmer, 1991;Brodie et al., 2009;Prasad et al., 2006;Sridhara et al., 2016). Otherwise, tropical deer are herbivorous (Sridhara et al., 2016), although opportunistic studies on temperate species have documented opportunistic carnivory through the depredation of birds' nests, insect consumption, and even scavenging of human bones (Ellis-Felege et al., 2008;Meckel et al., 2018;Pietz & Granfors, 2000;Shaw, 1963;Vazquez et al., 2023). ...
