First day on the porch

On the 14th, I spent a lovely Sunday on my porch playing with my new binoculars and watching some intriguing birds!  Here's what I saw:

Unidentified: 

•  Larger plump bird with a grey back and a dull yellow underbelly.  He also had (black?) eye rings and a stripe on his beak.  He was foraging on the ground and standing very tall, puffing out his wings a bit.

If anyone has any ideas what this birdy may be, please let me know.  I don't know if it was territorial or mating behavior but he stood up straight and would slightly open his wings and square up his shoulders.    

• Red Bellied Woodpecker:  He had a black body with white bars/dots and red on the top of his head, the sides of his head were white; he was chowing down on insects or whatever in the trees.  He picked at the bark rather than carving it out as most people would think with a woodpecker.  (This picture was not taken by me but is found on Cornell’s website).
   
  
  
   It's funny all of the beautiful birds you never notice when you're not looking for them.  We all notice the larger woodpecker that you can hear drilling a tree from a mile away; but this is a little birdy I had never noticed until I looked closely.  He doesn't loudly hack away at the trees, he sort of 'picks' at them instead.
