A Robin Has Been Sitting On My Fountain

I've got a small fountain in my small garden. It's pretty much a small ball on a small pedestal; there's a recirculating pump inside somewhere and the fountain bubbles up a couple inches when it's full, maybe a half inch if it has evaporated.

Just after lunch, I looked out my dining room window and there was a robin sitting on top of it. I've seen birds hopping through sprinklers, and I've seen them standing on top of our sprinkler back home waiting for it to be turned on -- but never seen one just parked on top of the bubbler. So it just sat there, occasionally moving over so it could put its head down and drink. If anyone went out, it took off a ways, but always came back.

It was a fairly warm day, about 88 or higher, and perhaps the robin found this Bird Jacuzzi was just right for conditions. Another bird sat on the fence, watching carefully (as birds do) and I think we may find them lining up for a few minutes worth of "sit time" on the bubbling fountain.
