My family and I are really into this bird watching thing this year. Girl2006 totally loves the Goldfinches. I keep buying up those sock feeders and they tear right through them. There are at least 7 of them that come regularly, they also like a metal one I put up on boy2001’s window… sometimes he scares them inadvertently but they keep coming back. Girl2004’s favorites are the hummingbirds… these are harder because they are very scary… so she also keeps and eye out for the Cardinals and the Black Capped Chickadees. I’m guessing I’m spending a good $10-$15 a week with this bird thing, that’s of course after the initial investment for the feeders.
