Loose Ends Department. I was lamenting the fact that, in a very short space of time last month, a couple of song-thrushes Smólach ceoil Turdus philomela whacked into our windows stunning themselves to death. Thrushes are doing quite well hereabouts, increasing rather than diminishing in numbers. Nevertheless, we'd rather make it harder form song-birds to kill themselves, even if they thereby provide food for ants. But inertia kicked in and nothing was done to stop the carnage . . . until on a single day in the first week of June 3 more thrushes, two juveniles, did for themselves against the glass. Although I had cogitated about dangling an old CD or two in front of the window to trigger a this-ain't-right reflex in approaching birds.
