We had 4 eagle (3 mature and one immature) sightings in Newmarket today near Barberry Coast Rd. One mature eagle was sitting on Vols Island minding his/her own business. Two other mature eagles did a very low fly by as they were either fighting or mating, difficult to tell, and took their quarrel out over the bay. As we turned around to walk away an immature had flown in and landed in a nearby tree.
