They always come in groups. I make the feeders and feeding the hanging wire through the piece of bark for a roof, you can just lift it up and drop another piece of suet in.
Our Long Tailed Tits come in little flocks too to feed on the fat cakes. Had to trudge my way through over a foot of snow today to fill the feeders but it was worth it.
Oh dear...I DEFINITELY need more coffee. Saw your post title, and I my first thought was "Kildale OMG!!!!!" ............I thought was I read was....."A bunch of bull@#$%" <gulping down more coffee stat!>
Nice one Kildale,..love the way you make up those feeders and even more so the flocks of bird life you attract,..i had to put on my knee high rubber boots to leave out nuts and fat balls for the birds,..lots of snow here
