Document Summary
Studying nest fate of northern pintails (anas acuta) through incubation recess. Duration and frequency, and how these behaviours are affected by predation, air. Incubation and nesting behaviour of northern pintails (anas acuta), pintail hereafter, was studied in south-western alberta, canada from may-july 2008. This study investigated the affect of incubation recess duration and frequency on nest success. I hypothesized that nest success will be minimally affected by incubation recess duration and affected more by recess frequency. Twenty-two active pintail nests were monitored by temperature monitoring devices placed in every other nest. These temperature signatures were used to calculate incubation recess duration and frequency and modeled using multiple logistic regression. Monitoring nests through duration of incubation period determined nest fate. The results show no significant relationship between incubation recess duration and nest fate but there is a significant relationship between recess frequency and nest fate.
