Northern Parula
Setophaga americana
The northern parula is one of the smaller North American migratory warblers, often being one of the smallest birds in a mixed feeding flock besides kinglets or gnatcatchers. Length is 10.8 to 12.4 cm (4.3 to 4.9 in), wingspan is 16 to 18 cm (6.3 to 7.1 in) and body weight is 5 to 11 g (0.18 to 0.39 oz). Among standard measurements, the wing chord is 5.1 to 6.5 cm (2.0 to 2.6 in), the tail is 3.7 to 4.5 cm (1.5 to 1.8 in), the bill is 0.8 to 1.1 cm (0.31 to 0.43 in) and the tarsus is 1.5 to 1.8 cm (0.59 to 0.71 in).

Yellow-rumped Warbler
Setophaga coronata
The yellow-rumped warbler has an average length of 14 cm and weight of 12.5 g, its appearance is different across its subspecies groups, especially the two major ones: the coronata group (myrtle warbler) and the auduboni group (Audubon's warbler); intra-group variations are also observed. In spite of varying appearances, the yellow rump (as suggested by its name) is present in all subspecies and thus characterizes the yellow-rumped warbler.
