Relative to the small branches, this quiz bird seems small and that feature, in combo with the fact that it’s perched in a tree, probably puts us in the large bird order, Passeriformes, which houses about half the world’s bird species. The pattern on the upperparts feathering is both intricate and subtle and provides a good clue to the family. It certainly rules most (all?) of the sparrows, blackbirds, warblers, and cardinalids, the last four families in the current taxonomic order. The lack of a very long claw on the hind toe rules out the pipits and longspurs (and Snow Bunting, but hopefully, no one started there). Also note the barring on the wing coverts.
