I birded for a short time this afternoon at the Fox River Sanctuary in Waukesha Wisconsin. Looking up, the trees were loaded with Yellow-rumped Warblers. I saw one Black-and-white Warbler in the mass of Yellow-rumps and just for a moment. A breezy day with temps about 50, the sun made for a very pleasant day. Images were taken on April 22, 2014. After the first 4 images are some Black-and-white Warbler images taken back on May 13, 2011 at Wehr Nature Center.
Binomial name: Mniotilta varia
Size: 5.25” long, 8.25” wingspan
Weight: .37 oz.
Habitat: Moist mixed deciduous-conifer forests or woodlots.
Diet: Mostly insects, while forging like a nuthatch along limbs and trunks of a tree. Some other items in their diet are ants, flies, spiders, leaf hoppers, wood-borers and weevils.
Nesting: Usually the cup shaped nest is on the ground, hidden near a stump, fallen log, base of tree, or under leaves or limbs with 4-5 eggs. Some of the materials used to build the nest are, horse hair, leaves, moss and grasses.
Great capture Jim, I have only seen one warbler so far, hopeful there will be more soon.
The thing I love about warblers is their beautiful colors. Then I see your images of the black/white warbler – and they are just as beautiful. I attribute that in large measure to your superb photographs. Thanks again for sharing your time and talents!
