Yellow-rumped Warblers at the Waukesha Fox River Sanctuary April 8, 2014.

I spent a short time down at the Fox River Sanctuary in Waukesha today and observed my 1st Yellow-rumped Warblers of the season. There were 3 present and they were hopping around in the trees eating what appeared to be small insects. I also enjoyed watching 2 different Black-capped Chickadees and 1 Red-bellied Woodpecker excavating nest cavities in dead trees while I was there. The sun felt nice, but it was chilly when it clouded over with the steady breeze.

Yellow-rumped Warbler

Binomial name: Setophaga coronata

Category: Wood-Warblers

Size: 5.50” long, 9.25” wingspan

Weight: .43 oz.

Habitat: Open coniferous and mixed coniferous-deciduous woodlands and edges.

Diet: Insects are their main diet, but depend on berries when insects are not available.

Nesting: The small shallow cup nest is built on a horizontal branch of a tree any where from 4’to50’ from the ground. The nest is constructed of grass, twigs, rootlets, with a inter lining of feathers with plant fluff that drapes over the edge of the top of the nest and partially covers the eggs. Female sits on 3-6 eggs that are white and incubates them for about 12-13 days.

Notes: The Yellow-rumped Warbler is known for one of the earliest warblers to arrive in spring and one of the last to leave in fall.

    Jim – what fun to see these feathered carpenters at work. They know just what to do – and each has the right tool. Thanks for tucking yourself away to capture these great images. I can almost smell the wood shavings…
