Campo Troupial Icterus
jamacaii (aka Troupial Icterus icterus jamaicaii, alternative spelling Icterus jamaicaii) Brazilian name : corrupião |

Bahia,
Brazil The Campo Troupial is found in north-east Brazil and is a Brazilian endemic. It inhabits drier areas such as caatinga and savannah as well as deciduous woodlands. |
||||
Many authorities such as Ridgely & Tudor and Howard & Moore treat the Campo Troupial as a sub-species of Troupial Icterus icterus. However, having seen this Campo Troupial and the Orange-backed Troupial I. croconotus, I am inclined to follow Jaramillo & Burke in separating Troupial I. icterus into 3 species. Clements accepted this treatment in his update of the 5th edition. | ||||
Campo Troupial differs from Troupial in having orange rather than white on the greater coverts, white on the wing restricted to the secondaries and a restricted area of blue skin round the eyes. Orange-backed Troupial has an orange crown, nape and back. |

Jaramillo comments that, like the other 2
troupials, Campo Troupial does not build its own nest but
piratises the nest of other birds. It prefers domed nests so the
nests most frequently piratised are those of species such as
Firewood Gatherer Anumbius annumbi and Rufous Cachalote
Pseudoseisura cristata. On the other hand, Steve Hilty in
Birds of Venezuela says that nest usurpation is not
reported for Orange-backed or Campo Troupials... so it looks as
though there are quite a few points about this species that need
clarification. |
