These were all shot yesterday at Galveston, Texas on Gulf of Mexico coast.
1 & 2 are of same bird that a birder next to me IDd as a Downy Ladderback hybrid. It does look like a downy face with a ladderback back.
3 is a different bird in same area. It looks weird also, but maybe just because of the head angle.
#4 - I don't know what this is.
#5 - Which grackle?
## 1-2 look like female Ladder-backed to me, I can't see any good reasons for hybrid
# 3 ditto male Downy
# 4 I'm thinking female Orange-crowned Warbler
# 5 Great-tailed Grackle for me, given the uniform purple iridescence
