Maybe not ID-able from the picture unfortunately, but I'm sure of what they were so please don't give a lower ID :). They were so cool though omg! They climbed the tree so fast, I was just left watching in awe before I thought to grab my phone. I’ve never seen a snake climb that fast and elegantly. Added a circle to the first picture to aid in at least seeing the snake, even if nobody feels comfortable to give a corroborating ID.
