3, see text The northern fiscal (Lanius humeralis) is a member of the shrike family found through most of Sub-Saharan Africa.
[1] This is a fairly distinctive 21–23 cm long passerine with white underparts and black upperparts extending from the top of the head down to the tail.
[2] The northern fiscal is usually solitary and hunts insects and small rodents from an exposed perch or the tops of shrubs.
Installing more artificial perches causes the fiscal to reduce its territory size and allow more birds in the affected range.
It gives a jumbled mix of shrike-like swizzling sounds including some imitations and a harsh Dzzzttt-dzzzt-dzzzt alarm call.
