Attached is an ebird report with images of Lawrence's Warbler which is a hybrid backcross with a Brewster's (first generation hybrid) and a pure Golden-winged (simplistic probability 1 out of 16 eggs) as this is the recessive genes.
The images show a bird holding food which means confirmed breeding. I am not sure where this is in Fowl Meadow, but anyone birding the area should pay attention and see with what this bird is paired.

awrence's Warbler (hybrid) (Vermivora chrysoptera x cyanoptera (F2 backcross)) (1) - Reported Jun 03, 2025 08:55 by Ethan Ripperger - Fowl Meadow, Norfolk, Massachusetts - Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-71.1313248&<ll...>,-71.1313248- Checklist: https://ebird.org/checklist/S246297180 - Media: 7 Photos - Comments: "I was scratching my head for awhile on this one. After wracking my brain for awhile the blue-ish wings made me think of a Blue-winged/Golden-winged hybrid. Some additional googling led me to Lawrence's."
