Blue Grosbeaks and Indigo Buntings at platform feeder - spring migration

The ebb and flood of Indigo Buntings (INBU) through Florida is much like a wave that moves northward during spring migration in April and southward during fall migration in October. INBU will always be around (they actually breed in the county in very small numbers). It's just that weather conditions and resource abundance along the migratory path sometimes allow them to keep moving overhead, barely observable in back yards. Other times, they settle in for a busy day, a few days, or, rarely, up to a few weeks.
Based on reports over the past three days or so and the sounds in my own yard this morning as I edited this video, today will be a big day for INBU at bird feeders in this area.
This video footage happens to also contain a lot of Blue Grosbeak (BLGR) footage. BLGR move through Florida similarly to INBU and they breed in the county as well but BLGR don't show up at feeders as commonly as INBU - except in yards like this one. It's in the rural outskirts of a rural town - Melrose. BLGR are more commonly found in such places.
This type of feeder activity is the reason that we encourage everyone to have at least a little bit of [white proso] millet in the feeder array through spring migration. Most people want to cut down on the amount of Mourning Dove activity once the Chipping Sparrows have left but we don't want to miss out on this!

The Indigo Bunting is presumably a male and is changing colors right?

Well, there's definitely one of those in this video but there's also a female that won't be turning indigo.
