Maintenance Energy Costs of Two Partially Folivorous Tropical Passerines (6523 words) |
 | We measured oxygen consumption (902) of six Grayish Saltators and four Orinocan Saltators in re- lation to ambient temperature (Ta) during the non- active phase with an open-flow Applied Electro- chemistry model S-3A analyzer as described in Weathers et al. |
| The de- crease in T b between 34 and 13øC T a that we estimat- ed from the regression equations was 1.9øC in the Grayish Saltator (from 39.5 to 37.6øC) and 4.1øC in the Orinocan Saltator (from 39.1 to 35.0øC). |
| However, the fact that saltators spend 77 to 80% of their time sitting, singing, and preening suggests that, under such a relaxed time budget, it is unlikely that they would be forced to forage or to spend con- siderable portions of time exposed to unfavorable ra- diative environments. |
| Saltator - Wikipedia, the free encyclopedia (116 words) |
| Saltator is a genus of birds in the cardinal family Cardinalidae. |
| The name "saltator'"is the English name for the group, and the English names of all except two species end in "Saltator". |
| Vieillot applied it to this genus because of the heavy way the birds hop on the ground (Jobling and Fowling, 1992). |
