We report the discovery of a resident population of Savannah Sparrows Passerculus sandwichensis wetmorei in grassland on a high plateau of the Sierra Los Cuchumatanes in western Guatemala. We observed a nest containing a nestling, and 11 fledglings of other breeding pairs in July 2016, which represent the first confirmation of the species nesting south-east of the Isthmus of Tehuantepec, c.700 km from the nearest known breeding locality in central Mexico. We provide the first description of juvenile plumage for this subspecies. Furthermore, we describe the song of P. sandwichensis wetmorei for the first time, which is similar in structure and signal characteristics to that of northern populations. Based on transects, we estimate a population density of 0.7-4.3 adults / ha in the study area, in the Parque Regional Municipal Todos Santos Cuchumatán, which is similar to published data from the USA and Canada. This is the first documentation of P. sandwichensis wetmorei since the type specimens were collected more than 100 years ago.

... It is rare south of 05°S in East Africa, and south of the equator across the rest of its wintering range. However, being a long-distance migrant, it is prone to wandering: the species is regularly recorded in coastal California in autumn (Tyler 2004) and has reached Guatemala (Matías & Eisermann 2018) and even Ecuador (Brinkhuizen et al. 2010). It has also been recorded in Australia (Carter 1997) at 18°S. ...

... Petén, in December 2010 (Jones & Komar 2011c) was the first there. The resident race wetmorei (van Rossem 1938) endemic to the west Guatemalan highlands went unreported for more than a century following collection of the type series (Eisermann et al. 2017a). Breeding was erroneously reported by Jones (2002), based on a report wherein the observer assumed nesting but did not observe it (J. ...
