Birds are blind

Evidently birds, or the ones at our house have seriously crappy vision. Either that or they're just plain dumb which could also be a possibility. Either way, have just had about 5 of them crash into the window of the study in the last 5 minutes or so. Hear this thunk every so often and sure enough it's another one. While the window isn't real dirty it is a bit dusty so you'd think they'd realise but no apparently not because tehy just keep crashing into it.
have the joy of trying to change shifts next week after I got rostered on for a day I'd asked for off so that should be fun. Especially since there're only about 2 people that could possibly do the shift but not too worried about losing those hrs since I managed to pick up an extra 6 for today after Moira realised she hadn't put enough people on for tonight so get to have most of the day off since i don't start til 4 and get extra hrs. All good.
