Quiz 32 – Warblers from below


This quiz shows warblers as they are so often seen in the field – with just the underside of the body visible. Clues such as tail shape, overall size, behavior and other subtleties can be very helpful with experience. In this quiz I focus on the more objective features of plumage.


When all you can see is the belly, flanks, and tail of a warbler, take note of tail pattern, any streaking, and the overall pattern of dark/light and bright/drab. You should be able to identify most species by matching those patterns to the pictures in the guide, and with practice you will recognize more and more warblers from these small clues.


With thanks, again, to Brian E. Small for providing the beautiful photos. You can see lots more at his website.

Question 1

Northern ParulaBlackburnian WarblerMagnolia WarblerYellow-rumped WarblerQuestion 1 Explanation:Northern Parula - the combination of yellow breast with unstreaked gray-white belly and flanks is unique to Parula. In the partly obscured view above the blue-gray wings with two short white wingbars help confirm the species.

Question 2

Magnolia WarblerAmerican RedstartYellow-rumped WarblerNorthern ParulaQuestion 2 Explanation:Yellow-rumped Warbler - This is a male, and the pattern of blackish streaks on the flanks and breast, leaving a tapered white belly patch is unique to Yellow-rumped. And of course the bright yellow patches on the sides of the breast are distinctive as well.

Question 3

Yellow-rumped WarblerPrairie WarblerMagnolia WarblerNorthern ParulaQuestion 3 Explanation:Magnolia Warbler - The pattern on the tail, white at the base and black at the tip, is unique and you don't need to see anything else to identify this bird. Also, no other eastern warbler has such thick black streaks on bright yellow flanks (Townsend's is similar in the west, but the tail is almost entirely white from below).
