During the last years of World War II, or shortly thereafter, a pregnant Brown Tree Snake (or brown Treesnake) hitched a ride to Guam by air buy more likely by sea.

If that is not true, then a male and a female Brown Tree Snake did the hitching.

Actually, a group of BTSs grabbed passage, perhaps not all at once.

Anyway, a caboodle of little BTSs were born and still thrive in Guam. They eat birds by the thousands.

Yum, Yum!

They eliminated several species of birds, lizards, and other insect-eating critters. They pick on the rodents too.

They are having a bonanza.

They are the only snakes there.

Well, not quite. There is the Ramphotyphlops braminus, a small worm snake that lives on the sandy beaches.
