Major Migration!

One glimpse at Saturday night's NexRad map over Wisconsin and I knew Sunday morning was going to be good. You can see migration over Iowa, Illinois, and Indiana, but the birds were stopped in southern Wisconsin by a strong thunderstorm. Sure enough, I went from a previous high outing total of 47 bird species to 59. New birds included Brown Thrasher, Eastern Towhee, Field Sparrow, Savannah Sparrow, Louisiana Waterthrush, Swamp Sparrow, and more. There were major influxes of Yellow-rumped Warblers, Northern Flickers, Yellow-bellied Sapsuckers, Chipping Sparrows, and Ruby-crowned Kinglets.

Yellow-bellied Sapsucker

The unseasonably warm weather (82 degrees F.) brought insect hatchings as well; I saw my first Mourning Cloak and Red Admiral butterflies of spring. This Round-lobed Hepatica was my first wildflower of the year:

  1. Nice sapsucker. It will be interesting to see what shows up on Nexrad images in May!

  2. Saw first YRW in Green Bay April 11, thats early here....Fox sparrows still hanging WT or WC sparrows yet as of this morning(suburban Green Bay), gotta show up soon-maybe mine got wiped out by some chemical down south.
