Buntings, Sparrows, Blackbirds and Warblers
The first gallery shows photos of Old World buntings (Emberizidae) and from the New World: American sparrows (Arremonidae), blackbirds (Icteridae) and warblers (Parulidae), see Taxonomic Classification note. I photographed them in forest and garden habitats. Both sparrows and buntings are seed eaters. Blackbirds generally feed on small animals, seeds, nectar, and fruit but not exclusively on all of them. NW warblers, also known as wood-warblers, are arboreal insectivorous feeders.

Blackbird and Warblers Notes
All featured species are ‘Red List 2019’ assessed as ‘Least Concern’. New World blackbirds exhibit size and some plumage dimorphism with females being smaller and duller in plumage than males. The yellow-hooded blackbird has more extreme plumage dimorphism, making it easy to identify the males from females.
Yellow Warblers occur throughout the Americas. There are 43 recognised subspecies, Yellow [Galapagos] Warbler (Setophaga petechia aureola) being one of them. The Galapagos subspecies also occurs on Cocos Islands and may be considered a near-endemic subspecies or even a separate species.

Buntings, Sparrows, Blackbirds and Wood-warblers Taxonomy
Core Passeroidea includes families from the Passerid Clade. The featured families include two Nine-primaried Oscines groups; both are part of the Icteroidae epifamily:
(a) Buntings and sparrows group that comprises Emberizidae (Old World buntings) and Arremonidae (American sparrows);
(b) Blackbird and warbler group which contain New World blackbirds (Icteridae) and warblers (Parulidae), the latter is also known as wood-warblers.
Epifamily is a rarely used taxonomic rank between family and superfamily.
The Passerida Photo Albums webpage gives an overview of applicable Aves High-level Classification.
