I have often seen both Red Tail Hawk and bald Eagles on 295 after Portland, heading North, on the water side. Though this isn’t necessarily the time of year for the Hawk as some fly south for the winter months. My husband and I saw 17 Hawks driving South on 95 (between Scarborough and Mass) taking our grandson to Mass, one year. But we always see them in the Spring, that is a actually a great place to see them.
