Abstract

Studies of spatial activity of songbirds during the nesting cycle have largely focused on male activity and neglected female space use, particularly outside the fertile period. We estimated the home-range size of seven female Dark-eyed Juncos (Junco hyemalis) 3 days after their nestlings had hatched. We used radiotelemetry to track female movements for 2 hrs on the afternoon of day 3 of nestling life, and 2 hrs on both the morning and afternoon of days 4 and 5. Female location and behavior were recorded every 10 min for the duration of tracking. Females exhibited a mean home-range size of 0.833 ha (range  =  0.156–2.450 ha). Our estimate of home-range size during the nestling period was significantly smaller than a previous estimate of female home-range size during the fertile period in the same junco population. Home-range size varied greatly between individuals, and the observed differences may be attributable to variation in resource availability.
