The catch and games in these communal food getting are equally shared that even the unborn child in his mother’s womb gets a share as long as the mother has done her share of participation in the communal fishing and hunting.
The giving of equal share to unborn child reflects the esteem and value that these people gave to the human person by making the unborn child have equal rights with the adult human being. This is how much the Tigwahanon values human life.
These people have tree houses called batangan built among the branches of a growing tree with the tree trunk as its solitary post. Their fishing implements are bu-o (bamboo fish traps) in varied forms they have learned to fish using hook and line called banowit.

The Tigwahanon are scattered all over the Municipality of San Fernando in Bukidnon close to the border of Davao del Norte. The term Tigwahanon may have been derived from the Tigwa River where the Tigwahanon inhabits its banks and watersheds (NCIP, 2003).
