Thought this may be interesting to hear what new birds visit your garden now that didn't before. For me on top of the list are Goldfinches. Take January last year they didn't show up at all it wasn't until August when I bought a new feeder (still used the same seeds sunflower hearts) and when I put it up they turned up and have been regulars pretty much every day. It's strange but also fantastic because they also attracted Greenfinches who I hadn't seen for years probably since early 2000s when I got into Birding I used to see Greenfinches a lot in the garden and on field trips. Stock Doves have also made brief appearances so I'm really looking forward adding Goldfinch, Greenfinch & Stock Dove to my Big Garden Birdwatch.
