Adult feeding rates increased slightly. Length and number of nest breaks, and total time off the nest by the female decreased, as adult feeding rates decreased only slightly. During the post-hatch stage, care of young appears to be divided evenly between females and males. Tape quality was poor in many recordings, and black and white recording prevented adult identification by band combinations. We are currently conducting another video study during the 1999 breeding season.
Recordings are in real time instead of time-lapse.
More precise feeding rates and food types delivered by each of the adults attending the nest might be available, which may help us relate parental behavior to nest success. This page was last updated on December 2, 2000.
