Police and animal rescue teams have been searching for the bull since Tuesday morning, using a helicopter and night-vision equipment, and have attempted to lure him with grain and a cow.
The dark-coated, 680kg bull has been affably nicknamed “Barney” by residents who have spotted it roaming across fields, roads and suburban front yards.
Frankie Floridia, of Strong Island Animal Rescue, told Newsday: “We’ve tried luring him with a cow, with horses.
“I’m out here with a (tranquiliser gun) looking for him, and I’m thinking, ‘I’m hunting cows in an Indiana Jones movie.’”
“It’s just frustrating. The longer it goes, you wonder what happens,” he said.
A “bull trap” using Barney’s feed from the farm did not successfully lure the bull, nor did using a cow in heat.
Barney is believed to be wandering around a part of Long Island with dense underbrush and pine forests, which rescuers say has hindered the search.
Mr Floridia said: “I’m not afraid of him being aggressive to humans.
“He doesn’t have horns, he’s not an aggressive animal. I think he’s going to see people and he’s going to run away.
“I’m just afraid, with the colour of his coat, he’s going to wander into a road in the dark and some driver won’t see him.”
Earlier this week, a portion of the Sunrise Highway was shut down due sightings of the bull.
Rescuers hope to move Barney to a sanctuary once he is located.
