Deerchaser007,
Here's what Steve Ditchkoff, head of the Wildlife Department at Auburn, had to say about their study:
I have a student completing his thesis on buck movements that has a lot of relevance to some of the things mentioned on here in the past day. When following bucks for 24 straight hours, we find that 2.5 year old bucks (the youngest that we monitored) frequently made what we called "exploratory" movements where they would bee-line (as described by BSK) about 1.5 to 2 miles and return immediately. However, we saw the same deer doing it in different directions on several occasions. Because of the extremely high proportion of mature males in this population, we interpreted these movements as a response to the lack of available does because the big boys were locked down on them. In essence, we believe they were actually checking to see if the "grass was greener". Of course, this is pure speculation. We are also seeing some movement patterns in high fences that would suggest that this is occurring there as well, and we will begin to examine this pattern this fall.
One of the chapters in this thesis is on home range shifts...similar to what BSK described. In the population that we studied, we are finding that it is the norm, rather than the exception, and it has huge implications for deer management, and some of the things we are talking about. You will definitely want to read this when it's complete.
