Cruz, Alexander (1978) "Adaptive evolution in the Jamaican Blackbird Nesopsar nigerrimus." Ornis Scandinavia 9: 130-137. From abstract: "Nesopsar's feeding habit probably evolved on the island in the absence of species of Dendrocolaptidae and Furnariidae specialized for arboreal rummaging. Compared with other icterids, Nesopsar has shorter legs and more curved claws, which are advantageous in arboreal (trunk) foraging."
