Birding Information

Horicon National Wildlife Refuge Spring 2021 Migration Report Horicon National Wildlife Refuge Spring 2021 Migration Report 5/5/2021 This is week eight of waterbird surveys at the refuge for the spring migration. Dabbling ducks were the most numerous waterfowl group this week. Their numbers total about 4,000 on this week’s survey. Three species had numbers over 1,000 - green-winged teal, blue-winged teal and mallards. Northern shovelers and gadwall were seen in the hundreds. There are still a few wigeon and Northern pintails hanging around. Diving duck numbers dropped to 550 this week. Six different species were seen this week. Redheads were the most numerous at just over 200. Ruddy ducks, ring-necked ducks both had around 100. Only a couple buffleheads, hooded mergansers, and scaup remain in the area. Canada goose numbers increased to 2,300 this week. The increase is from all the new broods being seen out and about. Other sightings to note: •Canada geese have hatched. You may notice some adult pairs with 20-30 young following them. Some adult pairs are aggressive and may “kidnap” another pairs young. They will keep and raise them as their own. •Watch for pairs of redhead ducks. Redheads nest at Horicon marsh. The pairs you see are looking for the best nesting spot in dead cattail. •Shorebird viewing continues to be best around the auto tour loop. •Black terns made their return to the marsh. They can be seen around the auto tour loop. •Common gallinules were spotted this week. A pair was seen along the floating boardwalk. Look for the bright red bill with a yellow tip. They will likely nest in that area. Happy birding!
