The bird, or birds, may have stayed throughout the breeding season. If they did pair up with Blue-winged females, they may have nested, and become much quieter and hard to find. Many people interested (some wanting to add them to a list), may have become satisfied once they saw the birds, and stopped looking for them.
In 2009 as a new birder, I was following at least two Lawrence's Warblers (Blue-winged/Golden-winged backcrossed hybrids) in Nashua. After the end of May, I found them very difficult to find, no longer sitting up on branches and singing for all to hear! Eventually, I found them in a nearby, but different location in the park, defending nests near to the ground on the edge of forest and field from a hunting hawk. They had taken Blue-winged females as mates.
The Golden-winged Warbler may have left the area, become victim to a predator, but might have stayed and mated with a Blue-wing. It might be a good spot to look for Brewster's Warblers (first generation hybrids) next spring!
Blue-winged Warblers do have an alternate song, and both species apparently can learn the buzzy vocalizations of each other.
