Birds trying to get in my windows

[Sarian]

Does anyone know what this means, if anything?

Earlier I was sitting on my bed and a chickadee came and was fluttering as close to the window as it could get, then lightly flew into it. Then another came and they both fluttered in front of the window, more came and some were resting on the sill and looking it. It was so weird. cool, but weird. My cats went nuts but they didn't stop the chickadees from continuing with what they were doing.

Okay, so that experienced ended after about 3 minutes, but just a few minutes ago, birds started doing it at my front window, cats again going nuts. But this time, sparrows, first 3 of them, then it looked like 5 or 6. Fluttering close as they could to the window, then landing on the sill and pecking at my window and even at the screens. The cats got up to the screen and they didn't even fly away. It was bizaare.

Last week I had woken up to a squirrel looking in at me on the sill. It was funny.

does this mean anything at all? Or just a cool experience?
