Behavioral changes of the Slate-throated Redstart (Myioborus miniatus) and the Collared Redstart (Myioborus toquatus) along an altitudinal gradient in the Monteverde Cloud Forest Preserve

Climate change has been found to affect the distribution of bird species in Monteverde, Costa Rica (Holmes 2000). In this study, the Slate-throated Redstart (Myioborus miniatus) and the Collared Redstart (Myioborus toquatus) were observed in the Monteverde Cloud Forest Preserve. Both altitudinal distribution and behavior were observed for both species. It was found that the Slate-throated Redstart has moved up in altitude. Further, observations for both species were compared using a chi square test, and there were significant differences between the two species, and also within the same species. This study shows that climate change is possibly responsible for the migration up hill, which in turn may impact the future behavior of bird species, competition and may cause extinction. Se ha encontrado que el cambio climático afecta la distribución de las especies de aves en Monteverde, Costa Rica (Holmes 2000). En este estudio, la especie de reinita Myoborus miniatus y Myoborus toquatus fueron observados en la Reserva del Bosque Nuboso de Monteverde.https://digitalcommons.usf.edu/tropical_ecology/1027/thumbnail.jp
