Hi Evelyn,
I do not think that the one in the bottom right is a rose breasted grosbeak. I am pretty sure that this is actually a Baltimore Oriole. It's a little hard to tell, but I think the breast is actually orange not red. I know that the beak is too thin for a grosbeak. (gross means large is German, so I think that is something to keep in mind). Also, I was also watching the Live Cam the other day, as saw quite a few of the Orioles, so that is my best guess I hope this helps. If someone else disagrees, please let me know. We are all still learning!
Thanks,
Terri
