Birds that were once rare in New York City have been making more frequent appearances in recent years, to the thrill of local bird-watchers. But that excitement is tempered by the knowledge of what may be causing these changes: warming ocean temperatures, melting snowpacks and wildfires.
“It raises awareness of what’s happening on the planet and that this is a concern, and it causes more people to care about what is happening with climate change,” said Heather Wolf, a birder and application programmer with the Cornell Lab of Ornithology. That excitement causes people to get involved with conservation efforts, she added.
Birders have also noticed a reduction in the number of birds passing through New York City, said Marshall Iliff, the project leader for the Cornell Lab of Ornithology’s eBird project. Many birders love to watch warblers on their southward migration in mid-August, but Mr. Iliff noted that the wildfires in Canada caused many birds to leave earlier than expected.
“It’s those kind of things that sort of raise the question of whether birds are going to be able to adapt to these changing environments,” Mr. Iliff said. He said that as the forests dry out and as fires increase, birds that are expected to be seen passing through Central Park in spring could become “these really rare, rare events.”
People who subscribe to Cornell’s E-Bird alert can receive updates on when a rare bird is in the area. Here are some of the rare birds that have been spotted in New York recently.
Brown Booby
The brown booby, a tropical species often found in the Caribbean, was once difficult to see in this country, even in Florida. But since 2010 or so, that bird has been seen “all up and down the East Coast, multiple times per year,” Mr. Iliff said. One was spotted on Coney Island on June 27.
The brown booby is a large warm-water species with brown plumage and a white belly. It has been seen farther north because of warming ocean temperatures, scientists say. It has also been seen inland, including in lakes in western Massachusetts, which birders find confounding because it is generally a saltwater bird.
Ms. Wolf suggested looking for brown boobies around New York Harbor or the Hudson River area. She recommended taking the NYC Ferry because “you’re going to see things that you couldn’t see just walking around the parks.”
It’s unclear whether the species will become a truly regular bird to encounter in the North.
Brown Pelican
The brown pelican is another southern bird that has been expanding its range northward because of warming ocean temperatures. The species has become a regular sight off western Long Island beaches over the past decade. Several were spotted on Aug. 6 at Manhattan Beach Park, and one was seen at Coney Island in July, Ms. Wolf said.
The species, which has a long white neck and yellow feathers on its head, has become common in northeastern New Jersey and the mouth of the harbor in western Long Island. “People that…
