I took this photo on Highway Z on my drive to the Horicon Marsh. Autumn is so beautiful in Wisconsin.
The Trumpeter Swans are growing and continuing to enjoy swimming in an area near the auto tour.
Some of the trees are at their peak and putting on a spectacular show.
This Green-winged Teal looks a bit rough due to molting. The Green-winged Teal is the smallest dabbling duck in North America.
They also enjoy Ballet.
This is the pretty female Green-winged Teal.
I love the interaction between the Green-winged Teal and the Canada Goose.
I believe these are Adult nonbreeding Dowitchers. The tiger striping on their tales is an identifying feature. It is amazing that standing on one foot is restful!
This female Northern Pintail enjoys chatting and swimming.
Swimming only briefly, the Lesser Yellowlegs took off shortly after I arrived.
Autumn is a great time to view birds that are migrating through the Horicon Marsh. What do you think this one is?
Here is another view. I would love to hear what you think in the comments section.
Comment: Jerry asked a great question in the comments area. What is a dabbling duck? Dabblers feed on the surface of the water by opening their beaks to filter out tiny organisms. They may also tip up, leaving their legs and tails in the air. They don’t like to submerge their whole body. These include Canada Geese, Trumpeter Swans, and Wood Ducks. Divers, on the other hand, dive underwater to feed. These include Pied-billed Grebes and Ruddy Ducks.
Bird identification can be a challenge and that is part of the fun of birding. It’s exciting to discover a species we haven’t seen before. Let’s take a bird ID quiz and start with the bird that was easiest for me to identify today. He was spotted along the south side of Highway 49. Do you know what it is? Your answer is worth 2 points.
It is a Ring-billed Gull. It is a bit hard to tell in this picture because the fish is partially impaled on the end of the beak, but there is a dark ring there. The Herring Gull has a red spot on the bottom part of the beak (mandible). The Ring-billed Gull has yellow legs. The Herring Gull has pink legs. Also notice that the Ring-billed Gull has a red eye ring around its yellow eye. You get extra points if you can identify the fish.
This is the next bird I saw. He was frolicking in the water, which is a bit unusual for this bird, in my limited experience. I have always seen it wading. Your correct answer is worth 3 points.
This photo gives us a solid clue as it reveals the bird’s yellow legs.
This is a Lesser Yellowlegs. The bill is dark and slender. The Greater Yellowlegs has a bit thicker bill with a slight upturn at the end. The length of the bill is about equal to the length of the head in this Lesser Yellowlegs. The bill is about 1.5 times the length of the head for the Greater Yellowlegs.
Now let’s look at the most difficult identification of the day. Is this the Short-billed Dowitcher or the Long-billed Dowitcher? Your correct answer is worth 5 points.
Here is another angle.
Apparently, the best way to distinguish the Short-billed from the Long-billed is by their call. You can listen to the Short-billed Dowithcher’s call here and the Long-billed Dowitcher’s call here. Today, there were several Dowitchers wading in the water and they weren’t talking. They were eating. They were probing their long beaks up and down in the water and mud like long sewing machine needles. I think this is the Short-billed Dowitcher. The Short-billed has an orange wash to the face, neck, breast, and underparts. It has variable spotting on the upper breast. The belly can include some white. The Long-billed is brick-red on the underparts and has dark upperparts with reddish markings. It has a barred breast with no white areas on the belly.
How did you do on the quiz? Did you get all 10 points plus the bonus points for the fish identification? I referred to Birds of North America: Eastern Region, Editor-in-Chief Francois Vuilleumier, Field Guide to Birds by Donald and Lillian Stokes, and The Sibley Guide to Birds by David Allen Sibley for my information today.
