Do you have any idea what this is on my pyracantha bush? I have two and both are similarly affected. But only on one large limb each.

This looks like sapsucker (type of woodpecker) damage on the branches.
The birds drill the holes to feed on the tree sap and insects that are attracted to the sap. Mature trees/shrubs can tolerate damage from sapsucker feeding and continue to grow fine for years. Occasionally in severe cases, the damage can lead to limb and trunk girdling which may kill the tree. Here is our webpage about sapsucker damage, which does include some preventive measures.
