They are all BCIs. BCL is Boa Constrictor Longicauda which is simply a "locality specific" BCI like nicaraguan or hog island. In other words, it is a subspecies. It's a little confusing.....
Your first male looks like possibly a nicaraguan. Here's a pretty good pic - Nicaraguan Boa. I think he looks very similar to this snake both in color and pattern.
I don't think your 2nd snake (the 1st female pictured) is a BCL. A notable feature on the BCL is their dark head and facial markings. Your snake's marking are quite light. It'll be interesting to see how she colors up as she gets older. She could be, but she could also be a normal columbian too.
We'd need to see more of snake #3 to take a guess with her. All I can see is her head and that doesn't tell me much. But I'd hazard a guess of normal columbian BCI - although she could be hypomelanistic, especially if she's that pink.
No matter what they are, they are all really nice boas! I especially like #2 - very cool pattern on her! And good for you for rescuing that boy - he's obviously much better off.![]()
