Summer’s Lingering Pelicans

Brown pelicans have become summer residents hereabouts, nesting on Smith and Holland islands in the southern Bay when the water is warm and fish are plentiful. This late fall, however, the big-billed birds have been sighted as far north as Ft. Smallwood Park and Ft. Armistead Park near Baltimore.
    “Seeing them that far north in the Bay in November is notable,” says David Brinker of Maryland Department of Natural Resources. “I don’t remember observations like this in years past.”
    As for explanation, Brinker explains that last month was warm “so the waters of the Bay don’t seem to be cooling as fast as they generally do. This means that fish are more active than usual, so the pelicans can still find food easily. So they’re sticking around longer than normal.”
    In a typical year, pelicans start migrating south in late October or early November. Leaving Maryland, most pelicans end up in Florida or the Caribbean islands for the winter. Some go as far south as the northern part of South America.
    In the Chesapeake, pelicans nearly disappeared in the 1960s and 1970s because the pesticide DDT weakened their eggs. They didn’t return until 1987.
    Now, Brinker says, “We have somewhere between one to two thousand breeding pairs of pelicans every summer. I think part of the reason we’ve had this great expansion of birds is that they’ve discovered the great resource of the Bay ecosystem, especially the menhaden.”
    Odder still, a small flock of white pelicans winters at Blackwater National Wildlife Refuge on the Eastern Shore.
    “Thirty to 50 birds have been spending their winters there for the past five or so years,” Brinker said.
    White pelicans spend their summers in the Midwest and west, nesting in freshwater wetlands, then typically wintering along the southern coasts of the U.S. and Mexico.
