Thank you all very much for the kind comments about my fieldfare mistle-thrush picture. And for all the insights into backups, TM and others, and the frailty thereof. Wasn't it Joni Mitchell who sang "you don't know what you've got till it's gone"? That gal just wrote the Mac-users' anthem, right there.
Another 100% crop - this time it is definitely a goldfinch! I'm getting some practice in with the 200-500, around our feeders.
