I was looking over some of my favorite footage of boas in the wild and I remembered this video.
It is not mine, but I will link it here as it is available on You Tube.
It is a perfect example of the hunting/ambush strategies used by boa constrictors in the wild. Note the habitat. Clearly, are the signs of human encroachment, yet the snake recognizes the prey options in the area and has adapted to live in areas populated by humans. This is common with many snakes.
If you listen to the narration, you'll hear that the snake was in the area for several days then possibly relocated or hid for a time and came back shortly after. This appears to be in the day time which indicates these snakes are not only nocturnal, but sometimes diurnal when there is a need. Note the body size and shape of this snake. It is in excellent condition IMO. This is a Central American boa and it seems to have no problem taking birds. I often provide quail for my boa which is a nice alternative to rodents.
Terrestrial and arboreal, or termed "semi arboreal" boas will utilize almost all options to get a meal. This one has found something in between.
Say what you want about morphs, fancy photography and staged background scenes, they certainly are fun to look at, however this RAW, wild, footage is truly what these snakes are about.

There are other videos like this, I just ran into this one again today and wanted others to see it.
