NEW YORK — Throngs of spectators lined the streets of New York on Thursday as colorful, high-flying balloons helped usher in the holiday season during the Macy’s Thanksgiving Day Parade.

The annual tradition, which dates back nearly a century, packed streets as a procession of giant inflatables and floats streamed for more than 40 blocks from Central Park to Herald Square.

Children balanced atop metal barricades and hung from scaffolding to watch the balloons amid mostly sunny skies and a slight breeze.

“Blue, Blue. There’s Blue,” yelled Divyam Kumar, 6, as his father helped balance him and his 4-year-old brother Aanu Aryan on a metal rail.

The youngster was referring to the star of the animated show “Blue’s Clues” — not to be confused with the international cartoon sensation Bluey, an Australian cattle pup making her parade debut.

Bluey’s balloon towered as tall as a four-story building and stretched as wide as seven taxi cabs.

Stuart, the one-eyed Minion, was also there to thrill the crowd.

Snoopy, dressed as an astronaut, again made an appearance, as did Papa Smurf, Ronald McDonald and SpongeBob.

This year’s parade, by the numbers: 16 giant balloons, 28 floats, 40 novelty and heritage inflatables, 12 marching bands, 10 performance groups, 700 clowns and one Santa Claus.

The procession of characters were being joined by singer Paula Abdul, in her first parade appearance; indie pop band Fitz and the Tantrums; boy band Big Time Rush; “Blue’s Clues & You!” host Josh Dela Cruz; singer Gloria Estefan; gospel singer Kirk Franklin; actor Mario Lopez; reggae star Ziggy Marley; and Miss America 2022 Emma Broyles.

Singers Joss Stone, Jordin Sparks and Betty Who will also be part of the festivities, as will the stars of Peacock’s “Pitch Perfect: Bumper in Berlin” — Adam Devine, Sarah Hyland and Flula Borg. Jimmy Fallon & The Roots will be on a float celebrating Central Park.

President Biden and Jill Biden called into the parade, as he did last year. Biden thanked firefighters, police officers and first responders, saying, “They never take a break.”

They thanked the troops and Biden said he would be reaching out to speak to some today.

Asked about their plans for the day in Nantucket, the Bidens said it would involve family, and some time spent locally, thanking first responders.
