Abstract: Starting during the month of February of 2008, and continuing
through August of 2008, white tail deer were observed two weekends per
month both morning and evening at three sites in northwestern Minnesota
for changes in levels of vigilance. It was hypothesized that levels of vigilance
in females would be greatest in late spring to early summer, during the period
when females have their young to watch. In addition, it was believed that the
offspring (fawns) would be less vigilant at younger ages, and would learn to
become more watchful as they get older. Sites included sixty and eighty acre
alfalfa fields, and a twenty acre open area of mixed grasses. The number of
deer present was much higher at all sites during the late winter observing
period with females being the dominant sex present. After completing the
observations, it was concluded that the amount of time that the female spends
watching is highest when they have young to watch after. Additionally, it was
found that the offspring vigilance increases as they get older. |
