On Saturday, I met Derek up at Horicon Marsh. Lately, the best shorebird habitat has been at Horicon and some rare species have been located. One of the rarest has been the a Sharp-tailed Sandpiper that has been seen off and on for the past week. While the sandpiper didn’t make an appearance there was still plenty to see.
When I arrived on highway 49 I saw an incredibly large number of birds on the mudflats to the south. Many were too far out to identify, but some of the closer birds turned out to be decent finds. Some notables were Wilson’s Phalaropes, Black-necked Stilts, and Short-billed Dowitchers.
On the north side of highway 49 were many Great Egrets and Great-blue Herons feeding on fish left behind by the drying water. Among the Egrets and Herons was a single Snowy Egret (a rare bird for the state with only a few reports each year). A few Least Sandpipers and Killdeer were also present.
After another quick scan of the south side oh 49 yielded no new birds, Derek headed out while I continued to the Auto Tour. I parked in the Auto Tour lot and walked down Old Marsh Road. Within 50 feet of walking I noticed a Least Bittern perched up on the reeds. This was the closest I had ever been to a Least Bittern so even though they aren’t rare it was a nice surprise. Farther down the road I added Sora, Virginia Rail, and Black Tern to my day list. On the way out of the auto tour I located a juvenile Common Gallinule.
Overall, I found several year birds with the Snowy Egret being the rarest. While the Sharp-tailed Sandpiper couldn’t be found, it was still a great day to be out.
