I didn't know what to expect when I first started filling the feeders at Llandegfedd but after only a week we had Marsh Tit and the species list has been growing ever since. We've had a few visits from Siskin though a bit randomly and finally the local Nuthatches have caught on. They were actually the slowest of the native species to get onto these feeders.. I'm not sure why that is but i'm happy they have arrived. Even if they do steal all the nuts...
