Saturday's snowstorm was followed by a strong cold front that pushed some migratory birds southward. Other bloggers who got out yesterday morning will probably have more birds to report than I do. In the afternoon I walked around Donaldson Park, my local patch. Despite not bringing my binoculars, I saw five Northern Pintails in the park's pond. I see pintails at that location only once or twice a year, and only during fall migration. These birds most likely arrived on the previous night's cold front and will probably depart in the next day or so.
