Brown Shrike
Lanius cristatus
This shrike is mainly brown on the upper parts and the tail is rounded. The black mask can be paler in winter and has a white brow over it. The underside is creamy with rufous flanks and belly. The wings are brown and lack any white "mirror" patches. Females tend to have fine scalloping on the underside and the mask is dark brown and not as well marked as in the male. The distinction is not easy to use in the field but has been tested with breeding birds in Japan where the female can be identified from the presence of a brood patch.

Southern Fiscal
Lanius collaris
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. The bird has a characteristic white "V" on the back and a relatively long black tail with white outer feathers and white tips on the other feathers. The bill, eyes and legs are black. Adult male and female common fiscals are quite similar except for the rufous lower flank of the female. The calls are a jumbled mix of shrike-like swizzling sounds including some imitations and a harsh Dzzzttt-dzzzt-dzzzt alarm call.
