(D.) nasuta presenta una distribucion cosmopolita, asi como una lista amplia de hospedadores definitivos que incluyen aves de las ordenes Galliformes, Gruiformes, Charadriiformes, Columbiformes, Psittacioformes, Cuculiformes, Coraciiformes, Piciformes y Passeriformes
[A new Emberizinae (Aves, Passeriformes
) of the Middle Pleistocene of the Buenos Aires Province, Argentina]
The assemblages are dominated by sea birds (74 to 91 percent), with passeriforms
and anseriforms making up the only other significant percentages (5 to 23 percent and 1 to 9 percent, respectively).
This unusual avian trait contrasts with the homeothermic pattern exhibited by most birds, in which a set [T.sub.b] is maintained within narrowly defined limits, despite larger variations in [T.sub.a] (Bligh and Johnson 1973), but it has been reported in a few tropical species such as sunbirds (Nectariniidae, Passeriformes
; Cheke 1971, Prinzinger et al.
Unidentified bird remains (bones and feather shafts) could most often be assigned to "large" (anseriform and galliform) or "small" (charadriiform and passeriform
) bird classes for biomass estimation, even if they could not be classified to order.
Results of the bloodmeal identification were 31% bovine, 24% unidentified mammal, 19% deer, 14% human, 7% raccoon, 5% rabbit and 2% passeriform
