Have looked a couple times but they won't stay still long enough for me to study the beaks. Some are mostly all black, less have light color but black on the tips. Maybe saw one with no black. I need to sit there a while and let them calm down. They aren't frightened of me just moving around all the time. Wish I had their energy. They actually come to my feet hoping I'm going to lean over and set down squished strawberries or some other treat. I want to see if one with a light beak calls so it will take some patience. I'll let you know.
