I agree with the other's IDs. Regarding #2, my first thought was Blue Grosbeak... is this a possibility?
Because of the extreme depth of the bill, basally, I considered Blue Grosbeak too, but the Avibase list describes it as "accidental" in Cuba. (No idea how good Dr. Lepage's information is for Cuba in particular, but no reason to doubt it either).I'd guess either that or an Indigo type bunting.
Avibase does mention Nutmeg Mannikin (Scaly-breasted Munia) too, but... doesn't really look like it.
i'm struggling to turn these into a munia sp. The beaks are just too large and the tails are too broad and rounded.
When exactly were these taken?
