Two red-tailed hawks are struggling to recover after being rescued this week from an area near Humarock Plaza in West Bridgewater, Mass.

Wildlife expert Jeff Thompson enlisted the help of Marcy Jeppe of the Charmacy Wildlife Center in Holbrook after the birds, a mother and baby, were found covered in a sticky black substance, unable to fly or eat.

“It’s the worst I’ve ever seen,” said Jeppe, who has spent 23 years rescuing wildlife.

She said birds may be at a center for some time as she nurses them back to good health. The mother, who is described as “an old bird,” almost died Friday night, she said.

Meanwhile, other birds in the family are crying for their return, she said.
