Thought it was a robin but beak is all wrong

Hi, this one is nesting in our office courtyard. I thought at first a robin since I saw some orange at the bottom of its throat, but the beak seems all wrong for a robin, not solid orange and seems longer. I haven't been able to find it gone so I can get a pic of the eggs, which would confirm if a robin (blue eggs). This is in central Oklahoma. Thanks for any help. Rick
