Another Sad Centennial: Dusky Discoveries

Dusky Seaside Sparrow, Oologist 31 -1914

A hundred years ago, there was still a tidy little list of North American birds whose nest and eggs had never been seen by white scientists. Among them: the dusky seaside sparrow.

The collectors of those days took their failure personal, and their inability to discover the home of

a bird whose range covered only a few square miles, and one that had been known to science for forty-one years, and whose nest had never been found, was a “slam” on the ability of us true Oologists.

In the early summer of 1914, Oscar Baynard and Henry Simpson set out to put things right. For a full week in May, Baynard and his “old side kick”

cruised the entire length of Merritts Island, visiting every place where there had ever been any records of the Dusky Seaside Sparrow…. on the morning of May 21st … I saw a Black Sparrow…. I killed the bird and upon dissecting same found it to be a male evidently in full breeding.

This sure made us feel good.

Encouraged, the collectors “plunged into the marsh” and quickly discovered “at least” twenty dusky seaside sparrows in the dense salicornia carpet. Four hours later, they had found no nest. Simpson suggested over dinner that the sparrows

did not lay eggs at all but had young like an animal.

And so after their meal, they took to the time-honored method of dragging the marsh with a weighted rope. It took no time at all before a bird flushed as if from a nest, which the searchers found and promptly collected, with its three “heavily incubated” eggs.

To say that we were elated is expressing it mildly and we did a regular Indian Tango or some other kind of dance…. We vowed we would find more nests or never leave the spot.

Baynard and Simpson lived up to their vow only too well in the days that followed, taking fledglings, nestlings, and two more sets of eggs. The third clutch they collected was so “heavily incubated” that one egg began to hatch on the way back to the boat; Baynard

was unable to save but one egg of this set.

“Save,” indeed.

Two of the nests and egg sets, along with the skins of the parent birds, were sold to John Eliot Thayer, of gull fame. Thayer in turn donated the first nest and clutch, collected on May 21, 1914, to Harvard’s museum, where they still reside.

Does it matter that, by my count, Baynard and Simpson killed at least 17 sparrows and sparrows in spe on those few May days a century ago?

I don’t know how to answer that question, or how to argue that the dusky seaside sparrow would have remained doomed regardless of the efforts of the collectors. But wouldn’t it be fine today to have seventeen dusky seaside sparrows and their hundred years of descendants buzzing away in the marshes of the Florida coast?
