Some years spring migration is early. Some years it’s late. March is the time for ducks, blackbirds, phoebes, and gulls. I’m waiting for Bonaparte’s gulls (Chroicocephalus philadelphia) to arrive.
Bonaparte’s gulls pass through Pittsburgh from late March through April. Seven years ago I wrote about their sudden appearance on 21 March 2012 on the Ohio River and at North Park.
Read about their arrival — and their unusual nest location — in this vintage article: Bonnies On The Move.
When will the “bonnies” arrive? It’s time to check the rivers. 🙂
