Registro documentado de Aguilucho Negro (Buteo albonotatus) en la Provincia de Misiones, Argentina

Abstract


 
 
 El Aguilucho Negro o Aguilucho Jote (Buteo albonotatus) es una rapaz neotropical que se reproduce desde Norteamérica hasta el centro de América del Sur. En Argentina, la especie cuenta con pocos registros hasta la fecha. En la provincia de Misiones, el Aguilucho Negro tiene sólo dos observaciones, pero las mismas son no documentadas. En este trabajo presentamos el primer registro documentado del Aguilucho Negro para Misiones.
 
 

Family group structure of the endangered Yellow Cardinal (Gubernatrix cristata)

“…31 However, it is unknown in what proportion this behavior occurred in that province as Marateo et al 31 did not provide detailed information on the composition of family groups. In the other studies on reproductive biology of the species in the Argentinian provinces of Corrientes, 13 San Luis, 14 La Pampa, 16 and Río Negro, 9 only monogamous pairs were reported, except for one uncommon polygyny case, with a male attending three females from different nests during the same breeding season in Río Negro. 9 Likewise, we did not find any record of unusual Yellow Cardinal family groups with extra adults on citizen science platforms, suggesting that this behavior is uncommon through the distribution of the species.…”

“…independent populations with different allelic frequencies of loci) 18 , however, some breeding traits are only known for three of them. 9,13,14,16,17 In this work, we evaluate the family group structure of the Yellow Cardinal during the reproductive season in La Pampa province in central Argentina.…”

“…Clutch size is of one to four eggs and one to three chicks may fledge from the nest. 9,[13][14][15][16][17] Despite being threatened and occurring throughout a relatively wide area, the Yellow Cardinal is a poorly known species whose life history traits have been scarcely studied across its range. 12 In fact, this bird has at least four genetic management units (i.e.…”
