Abstract

The natural history and breeding biology of species in the genus Arremon (Passerellidae) remains incomplete. Here, we document an early nest record and provide additional notes on the breeding biology of the Chestnut-capped Brush-finch (Arremon brunneinucha suttoni) from the Sierra Madre del Sur in southern Mexico. We found one bulky, open cup nest with two pale blue eggs. The nest was found greater than one month prior to previous nest descriptions, suggesting a possible shift in breeding phenology. Future studies across the range of A. brunneinucha will help clarify our findings within the context of geographic variation in this species and possible causes.
