    We document the elevational range expansions of two Nicaraguan bird species, scaled pigeon (Patagioenas speciosa) and collared plover (Charadrius collaris). The previously reported elevational range of Patagioenas speciosa was sea level to 600 m. We observed the species in shade coffee at Santa Maura farm at an elevation of 1115 masl. Historically, the second species, Charadrius collaris, was known to occur in Nicaragua in coastal and wetland habitat at elevations not exceeding 50 m. On two occasions, the specie was observed in lacustrine habitat (Lake Apanás) at an elevation of 960 m, not unusual in the region. Historical and contemporary knowledge of avian distribution patterns within Nicaragua’s borders is important in terms of monitoring biodiversity, and is becoming increasingly more urgent as lowland species attempt to colonize higher elevations because of climate change and global warming, and thus run the risk of not being able to establish a foothold in disparate highland habitat.
