Birds Gear Up for Spring Courtship

So many birds! There are dozens at the feeders at any given time, now ... redpolls, chickadees, woodpeckers and even a couple house sparrows ... but it seems like there are more than there have been all winter. Also, they have started whacking into the picture window again. This is a sign of spring, I've heard, because they are ramping up into dating season, showing off for each other and not paying attention to where they're flying.

S-hooks, here I come! Nothing we've tried so far, to make the birds notice they are approaching glass and not trees, has done the trick. Pretty things attached by putty, hanging in front of the window, don't stay put; nor do the stained-glass hangings we tried. They fall on the ground and break or get run over by the lawnmower. I haven't found those shiny strips of reflective material that scare birds off; don't know where to get them, but experience to date shows that the wind blows foil balls hung on string up and into the eavestroughs, thus blocking the rain runoff. There's a net you can hang in front of the window, but that will be a last resort. First, I'm going to hang chimes and such from S-hooks fastened onto the eavestroughs. Scott doesn't want me to, fearing they will mark up the nice new eavestroughs. But: on one side, the safety of birds; on the other, pristine-looking eavestroughs. Sorry Scott.
