Signs of spring

The wattle has been blooming for a few weeks now (yes, I know, I should post a picture soon), and the last couple of nights on my ride home from work I've been able to look into the sky and watch a flock of bats flying south on what appears to be their annual migration. I'm not totally sure where they go, but it seems to be a common sight during the evening at this time of year, right on sunset, thousands of bats passing by, heading south, ever south. It's apparent they're looking for cooler climates, and I don't think it's a coincidence that day time temperatures have warmed slightly in the last couple of days.

This evening I found myself wondering exactly where they'll go, and indeed where they came from. How much of the world do they see every year on their migration? Is the migration something they look forward to? Something they view in the way our species would view a holiday? Do they marvel at the scenery they pass over along the way? Or do they perhaps become bored with it all, passing over the same part of the world time and again every year?

If I get the chance this weekend, I might look up google and see if I can find anything out about this migration. I'm a little curious right now. Of course, it might end up posing more questions than it actually answers, but it should be an interesting experiment either way.
