It's amazing to me the effect that my birdbath and my tiny flower garden has had on the amount of activity in our backyard. When we first moved into our house in 2003, the only birds we saw were sparrows, starlings, pigeons, and crows, which is pretty normal for this close to the city.
This year, we've got robins, blue jays, mockingbirds, cardinals, blackbirds, chickadees, and now - an ORIOLE! I couldn't believe it! I've only seen two orioles ever in Massachusetts in my life, and on Saturday morning, one was drinking from my birdbath. We spotted her (I think) two more times during the weekend. We also watched a heron fly overhead on Saturday afternoon! I wish I had pictures. I'll have to set up a camera and leave it pointed at my birdbath.
I've noticed more butterflies as well - in number and kind. We get a lot of the "plain" white ones, but now we're starting to see other colors, too.
I'm creating my own little wildlife sanctuary in my teeny backyard! :-)
