Variation in dark-eyed Junco (Junco hyemalis) nest mass and nest size across an elevational gradient in Southeastern British Columbia Lee, Joanna K.

Abstract

I explored the variation in dark-eyed junco (Junco hyemalis) nest mass and nest size across an elevational gradient in Revelstoke, BC. I predicted that mean monthly temperature during the breeding season would be lower at high elevation compared to low elevation. I also predicted that nest mass and external diameter would be greater at higher elevation compared to low elevation, while there would be no elevational difference in internal cup diameter or internal cup depth. Results show that high elevation temperatures were significantly colder than low elevation temperatures throughout the breeding season (P
