Hello, Robin! Where do you nest?

Short answer:
Turdus migratorius (Linneaus 1758) nests between the crow (Corvus) and the jay (Cyanocitta) in the large reptile tree (LRT, 1232 taxa) based on skeletal traits. 

Figure 1. Turdus migratorius, the American robin, nests between the crow (Corvus) and the blue jay (Cyanocritta).

According to Prum et al. 2015
which tests DNA sequences, Turdus nests with 13 taxa not tested in the LRT along with Corvus, the crow. So there is some agreement here. However, the basal taxon in this subclade within a larger clade, Passeriformes, is Menura, the lyrebird.

By contrast,
in the LRT, Menura nests with cuckoos, apart from crows and jays.

Ironically,
the genus Passer (the sparrow) was not included in the Prum et al. study. In the LRT, Passer nests between chickens and parrots, apart from lyrebirds, robins, crows, and jays. So the Prum et al. study does not tell us if Passer is a passeriform or not. In the LRT, the lyrebird, crow and robin are not related to Passer.
