Welcome to May!
The storm system responsible for a week of northwest winds, overcast skies, and rainy weather is finally moving east of Wisconsin. Consequently, there wasn't an influx of warblers that generally occurs during the last week of April.
Number of warbler species at Pheasant Branch Conservancy for April:
Only six warbler species last month! This is well below average and the lowest April warbler count I've ever recorded at the conservancy. Individual numbers are down, too, but in looking at the following tables from eBird, you can see the significance of the last week of April (26-30 column). A week-long storm system like we just experienced will definitely stall migration into May. Without this storm event, I think we might have had a more typical late April push of warblers like the 2010 table shows.
Non-YRWA warblers were pretty scarce April 2014.
April 2010 was typical.
Birders were spoiled April 2013!
I found seven warbler species this morning, including a Black-and-white Warbler. There was also an Ovenbird, a Nashville, Orange-crowned, and a couple dozen Yellow-rumped Warblers. With the weather improving over the weekend, we should see a noticeable increase in neotropical migrants!
