Breeding Biology of the Red-Bellied Grackle (Hypopyrrhus pyrohypogaster): A Cooperative Breeder of the Colombian Andes
The Wilson Journal of Ornithology
We document the breeding behavior of the Red-bellied Grackle (Hypopyrrhus pyrohypogaster: Icteridae) from monitoring seven breeding groups during 4 consecutive years (2006)(2007)(2008)(2009) in the central cordillera of the Colombian Andes. All nests were attended by three to seven individuals, representing family groups composed of adult males and females, as well as immatures from previous generations. Clutch size ranged from two to four eggs and was positively correlated with family groupdoi:10.1676/11-117.1 fatcat:de73berxgbc53iuwvkvz6i5ctu
