    This is a remarkable story and thank you for providing it to the bird-lovers on this blog! I would just like to know why the birds seem to have given up on visiting our feeders recently. It seemed as though we had flocks last winter and it has really dropped this year. Anyone else noticing the same thing?

    don’t know where you are Virginia, but maybe it is somewhat different weather patterns. it also depends what kind of birds – if there were a whole lot of house finches – they are subject to disease-related die-offs – and concentration at feeders may play a role. Other species may be affected, too.

    On a positive harbinger of spring note: There were red-winged blackbirds calling from a willow thicket on the Boise River in town yesterday. Mid-February is mighty early.

    ALSO – for any bird fanciers – I saw this yesterday – WHAT did they expect -building window sills out of styrofoam? Go acorn woodpeckers – and the landowners should just shut up!,0,2231757.story

    The picture is great. One wonders what other high quality building materials were used … besides a lot of glue or something.

‎"At some point we must draw a line across the ground of our home and our being, drive a spear into the land and say to the bulldozers, earthmovers, government and corporations, “thus far and no further.” If we do not, we shall later feel, instead of pride, the regret of Thoreau, that good but overly-bookish man, who wrote, near the end of his life, “If I repent of anything it is likely to be my good behaviour."
