Veeries that arrive first to breeding grounds are usually older males. You are correct that Veeries delay song for up to two weeks after they arrive on breeding grounds and often are very difficult to find during this time. This is well documented. Females arrive soon after males but the males still don't sing. Instead, they spend much of their time mate-guarding females - no time to sing. Only after females are incubating do males sing regularly. I'm not aware of any other North American songbird that exhibits this behavior to this extreme.

Every spring I see Veery Thrushes many days before I hear them sing. Are these males that feed and replenish their energy before singing, males getting reaquainted with their territories, females, or birds migrating through? Bird banders likely know these answers. Each springtime I hear migrating Hermit and Swainson’s Thrushes sing during migration, but their songs are soft and inconspicuous compared to their territorial songs farther north in Pennsylvania. The Veery Thrushes that I saw today were along Seglock Run and along Laurel Rd.Stanley C. Stahl
