Quiscalus

El zanate Quiscalus mexicanus, es originario de la vertiente del Golfo de Mexico y fue introducido al centro del pais en la epoca del octavo emperador azteca Ahuizotl, entre los anos 1486 y 1502 (Haeming 1978, Christensen 2000).

Biologia reproductiva del tordo negro (Quiscalus lugubris).

Second, for colonial species such as the great-tailed grackle (Quiscalus mexicanus) and most oropendolas and caciques (Psarocolius and Cacicus spp.), social pair bonds are not formed and several males attempt to copulate with the same females, making harem size difficult to estimate (Robinson, 1986; Webster, 1991).

Venous blood gas and lactate values of mourning doves (Zenaida macroura), boat-tailed grackles (Quiscalus major), and house sparrows (Passer domesticus) after capture by mist net, banding, and venipuncture.

In Florida, avian species in the families Cardinalidae (northern cardinal, Cardinalis cardinalis), Columbidae (mourning dove, Zenaida macroura), Corvidae (blue jay, Cyanocitta cristata), and Icteridae (common grackle, Quiscalus quiscula) are frequently exposed to SLEV (14).

In previous studies, numerous avian species like European starlings (Sturnus vulgaris), house sparrows (Passer domesticus), feral pigeons (Columba livia), red- winged blackbirds (Agelaius phoeniceus), common grackles (Quiscalus quiscula), brown headed cowbirds (Molothrus ater), American kestrels (Falco sparverius), Canada geese (Branta canadensis), mallards (Anas platyrhynchos), cedar waxwings (Bomby cillacedrorum) and yellow-headed blackbirds (Xanthocephalus xanthocephalus) also showed the similar results and suppress the depredations when seeds treated with anthraquinone and methylanthranilate were provided to the birds (Cummings et al., 1998).

Las especies mas abundantes en la zona de estudio fueron: Cathartes aura, Progne tapera, Charadrius wilsonia, Quiscalus mexicanus y Egretta thula (Tabla 2).

In contrast, the low scores for residential sites indicates the dominance either by species that are very abundant (e.g., great-tailed grackle, Quiscalus mexicanus) or that are nonnative (e.g., Eurasian collared-dove; European starling, Sturnus vulgaris; house sparrow, Passer domesticus).

The term "blackbird", when used in reference to agricultural pests, refers to red-winged blackbirds of various sub-specific designations (Agelaius phoenicius Linnaeus; Passiformes: Icteridae) and boat-tailed grackles (Quiscalus major Vieillot; Passiformes: Icteridae) as well as other blackbird and grackle species.
