Warbler Identification

Yellow-rumped Warblers, Townsend's Warblers, Orange-crowned Warblers, and a treasure-trove of these beautiful birds.

One of the largest and most diverse of bird families, warblers are some of the most striking birds you can find in nature. Ranging in color from the brilliant yellow of the Wilson's Warbler and Townsend's Warbler, to the sherbet-orange color of the Prothonotary Warbler and the dark blue and black of the Black-throated Blue Warbler, this group of special birds ranges all across the U.S. and make for some often challenging identification.

Once thought to be two distinct species - Audubon's Warbler in the west and the Myrtle Warbler in the east - we now now that the Yellow-Rumped Warbler is a hybrid between these two slightly different types of warbler. These little birds are striking to look at. The give-away for identification is the flash of bright yellow you'll see in the rump area of the bird as it flies off. We've not observed these birds flocking together like Chickadees or Kinglets - in our garden, it's common to see a mating pair of these birds hopping about the trees or bushes near the birdfeeder, in amongst the sparrows and titmice. The Yellow-Rumped Warbler does not frequently move south for the the winter like other birds, and likes to spend its time up the north of the United States.

Common Yellowthroat Common Yellowthroat | Geothlypis trichas | 4 ½" - 5 ¾"

Townsend’s Warbler Townsend’s Warbler | Dendroica townsendi | 4 ¼" - 5"
This bird is extremely unique in appearance. Note that black chin and facial stripe, with the little golden patch on the ‘cheek’, just below the eye. And talk about color! In the gloaming of the forest, this bird first struck me as almost orange in hue, the yellow was so vivid. Read Article »
Wilson's Warbler Wilson's Warbler | Wilsonia pusilla | 4 ½"
From the depths of the new leafy growth, we heard a series of rapid chchchchchchchchch calls. Squinting, ducking, standing on our toes, we were suddenly rewarded with a glimpse of a Wilson’s Warbler flitting amongst the branches. Read Article »
Yellow Warbler Yellow Warbler | Dendroica petechia | 4 ½" - 5"
Sweet sweet sweet little more sweeeet. This unusual snippet of birdsong rang a bell in my mind, and as we abandoned our picnic to locate the source of the song, I managed to get my memories in order. And then we saw him. There in the brush, more yellow than your symbolic idea of a canary, and with the faint striping on his breast. Read Article »
Yellow-rumped Warbler Yellow-rumped Warbler | Dendroica coronata | 4" - 5"
In general, the mature male shows more black both on the face and breast. His throat is canary yellow - what a sight! This winter, I have become even fonder of the Yellow-rumped Warbler, after many days of gazing at him. He is as spry as a cricket and as cheery as a dear friend. Read Article »
