Does anyone know why a blue tit would be angrily fluttering up and down my kitchen window .
Its walled patio with a large olive tree and various herbs dotted around bordered on one side with an extension wall with a flat roof and ivy on three sides around the kitchen window we have grape vines on trellis.
We have a bird feeder tray on the patio table and a feeder hanging .
Above the flat roof we have some sparrow nest boxes but all the blue tit boxes are in the main garden .
We do see many birds feeding in the patio area including on one occasion a sparrow hawk who had the manners to sit on the carver chair while eating his unfortunate victim
However weve not seen this before with a blue tit.
