In my yard, I have a small pond feature (~50gal) which contains three goldfish and a couple species of plants.  I also run a filter/pump combo to  assist in keeping the water moving, clean and aerated.  Also in my yard, I have several raised beds where I plant a mix of annuals, biennials and perennials all with the intent of attracting primarily birds.  I feed year round with seed (sunflower {mostly Black-oil}, millets and Safflower), nuts (peanuts out of the shell) and during the warmer months of spring/summer/fall, I offer sugar water for the Ruby-throats and Baltimore Oriole.  A few years ago, I planted a Pin (or Fire) Cherry - Prunus pensylvanica in my yard to attract insects and of course, birds.

This year I've learned that I have quite a bit beyond my bird feeders.  I have trees with nuts - oaks, hemlocks, and beech and trees with fruit - sassafras and serviceberry. I have good shelter with three large hemlocks.  I never paid much attention to them before this spring when I started doing a weekly survey using Nature's Notebook. I started working in native plants last year and also began leaving the leaf litter on the ground. This year I've seen lots of ground foragers in the leaves and under bushes - like sparrows and thrushes. I had a small wood pile this winter for the first time and noticed a Carolina Wren around it almost daily.  I'm retired now and obviously will have to pass this house on to someone else down the road. I want to make sure I have plenty of native plantings around the yard so that even if the next owner is not into birds/wildlife the yard will still be a suitable habitat for them.
