The Black birds nest in my Montana & I notices that the old wool moss in the hanging baskets is a bit ragged, so it looks a s though they are pincking it for nestin material. I'm glad you've got sparrows, all this talk about them being rare I was getting a complex as I thought they were all in my gardenl!! I live about 300yds from 260 acres of mixed woods and get about a dozen species at most in my garden, my friend lives about 3 miles away got 30 odd when he did the survey the other weekend!
I get loads of Goldfinches & Greenfinches especially in the Silver birch (no Siskins yet

) but I was saying to Jax or LJ that I put up a half coconut with a fatball mix in it & it's hardly been pecked The 3 feeders I had up I've got soaking cos the seed went off in them & set rock hard! My friend has to fill his feeders about 3 times a week!!! He has no bushes in his garden at all, I've got loads can't understand it. I think there is too much food available loacally to me thats the trouble.
