One reason could be if you are using any kind of reciprocal advertising service for your site.
The most obvious such program is Traffic Exchanges.
These kind of programs can be useful for building awareness that your site is out there. I use them myself, but they are fatal for bounce rate as hardly anyone is going to dig deeper into your site.
If you are using such programs, you need to either create a duplicate landing/index page on a completely different hosting service and URL which then links into the main site should anyone click any link, or use a 'splash' page that gives some initial info on your site with a call to action.
