Observations

  1. Number observed: 3

    Details: Very rare in Middlesex County in the winter. Three large, dark soaring birds were seen while driving south on 495. I thought they might be the more probable ravens or eagles, but eventually I could see short tails, small heads, and silvery undersides to the primaries. Fortunately they flew right over the highway as I was passing underneath, allowing for a brief but identifiable view.
