I have no explanation, but in response to the titmouse mirror behavior, I have had two different species of birds seemingly "sparring" with their reflections in the glass of my bathroom window for the past two springs. Last year it was a cardinal and this year a robin. Females in both cases. They are extremely persistent, going at it for minutes at a time (often waking me up on the weekends). What on earth could this be about? It would seem to make more sense if they were males. K.
