Abstract

The Golden-crowned Flycatcher (Myiodynastes chrysocephalus) inhabits the Andean rainforests from Peru to northwestern Argentina. Its presence in the southern portion of its range, i.e., the Austral Yungas of southern Bolivia and northwestern Argentina, has been poorly documented. In this study, I analyze its distributional range, particularly the southern portion, from a historical and spatiotemporal perspective, using reports from collaborative platforms. Also, I report its presence in San Salvador de Jujuy, a new location for this species that expands its range. The Golden-crowned Flycatcher was first recorded in Bolivia in 1936 and in Argentina in 1991. Reports in the Austral Yungas were scarce and scattered until 2018. The southern limit of its range has not shown a consistent trend of expansion southward in the last 20 years. Furthermore, its presence in this region is seasonal, with frequent reports of individuals and breeding activity from October to March, and an absence of records from June to August. Given this pattern, I discuss the possibility that southern populations of the Golden-crowned Flycatcher could behave as austral migrants in the temperate-tropical system, a behaviour previously undocumented for this species.
