To celebrate the arrival of April I was out birding today at Knoch Knolls Park in Naperville, Illinois, thinking about how another winter has passed with no sighting of my nemesis bird, the Snowy Owl. I had hoped to finally match this check on my brother’s bird list, closing the gap just a bit. Not many birds, really, just the occasional American Robin and Chipping Sparrow, but as I wandered my eye caught something in the few patches of snow left in the park.
