My bird cafe is very popular but I am finding the nyjer seed a problem and wonder what others do. I love watching the gold finches swinging and pecking away but it seems more lands up on the ground than in their tummies and it was only when I began to notice a smell that I decided to finally try and clear it up. I was shocked that there was this thick, evil smelling carpet of the stuff on the ground, probably because it's been so wet. Some of it is paved so could be scooped up but much is gravel and I have no idea how to get rid of it or how to stop so much falling. No point hanging anything under the feeder with our winds.
I use squirrel cages for other feeds and love watching the birds pack into them. Long tailed tits love the fat balls (counted 7 in the cage once - quite tame and so sweet), sparrows go for mixed seed and also pack into the cage, other tits prefer nuts and seem to prefer solitary feeding. Haven't worked out yet how to put seed on the ground for robins without attracting big birds as they don't seem to like the squirrel cage and I refuse to feed jackdaws.
