Thanks everyone for the comments and "likes"! I have seen indigo buntings before, but had never had the chance to photograph them. The blue grosbeak I'd never even heard of (most of my time is spent in upstate NY and New England or Canada, range maps show it as a more southern species), so that is an addition to my life list.
In case anyone is curious about the EXIF data for the blue grosbeak - I did not consciously choose to shoot at 1/200. I had the camera set in manual with auto ISO and the dial must have gotten jostled as the camera rode in a daypack while I was riding the bike. After shooting the grosbeak, I noticed the shutter speed was way low (I like 1/1500 and ISO 400 for walking around settings) and made the adjustment for the next bird (which happened to be a snowy egret fishing in a little creek, then the buntings were just a little ways past that.
