WHY TAP ON WINDOW?
We have a pair of Dunnocks, which we think have nested. Outside our kitchen window we have a clematis and the male Dunnock has been landing on it and flying around it, wings flapping and tail up. It then goes on to the lower part and starts to fly at the kitchen window, tapping it with its beak. We have a flowering orchid on the sill and we thought this was what was attracting the Dunnock. We moved it but the bird is still tapping. Is it possible the Dunnock sees a reflection and thinks it is another Dunnock? Neale Rowley
QDunnocks can be very aggressive little birds, not least because of their, how shall we say, ‘colourful’ sex lives. This one is almost certainly seeing its reflection as a possible rival for the affections of its mate or mates, and is attacking in an attempt to drive off the ‘other Dunnock’. This is quite common behaviour in Dunnocks and certain other species, such as Robins and wagtails, which are also fiercely territorial. One way to stop this behaviour, enabling the bird to preserve its energy for more important things, is to put some cling film or non-reflective cellophane on the window in question.
