Several group members have been checking Tawny Owl boxes in the last week or two and the emerging picture seems to be average occupency and below average brood sizes (mostly 1s and 2s). A female near Kirklington had first been ringed in 2013 and was at least 3 years old then. She has been processed ten times in the same box with only one year with no breeding in the box. The photos below also show the colour variation in adults well.
