Tundra Swans versus Trumpeter Swans

        It's swan season and when birders get together, the subject of how to identify swans seems to be coming up quite a bit. So what is it with these Tundra and Trumpeter Swans? They are both big white birds with black bills. Their names even sound alike, adding to the confusion. They can turn up separately or together almost anywhere. I had a flock of 60 Tundra Swans fly over my house once, for Pete's sake. If they call, that is very helpful in separating them, but what do you do when you have a bunch of swans standing silently in a corn field? I have been lucky enough to run into quite a few swans recently in these very circumstances, and I have a couple of photos that might help people start to sort them out.The idea here is to learn to separate them in less than ideal conditions - the way we usually see them. So even though a yellow loral spot (in front of the eye) or a pink lip stripe are diagnostic field marks, often times these are not useful in the field.

        The Trumpeter is the one with the pink lip stripe, if  you get a lucky look in good light. But we can't see that in this photo. The area we want to focus on is around the eye. In these two birds, you can't really see the eye. Notice also the angle formed by the back edge of the bill between the eye and the "chin."  Now compare these areas with the same ones in the swan in the next picture.

        On the Tundra Swan, the eye is distinct from the bill. Part of this is because of the structure of the bill, and part is an optical illusion caused by the yellow loral spot, in front of the eye. Most Tundra Swans have this spot, although it can vary in size and be hard to see in some birds. Also, to me, the Tundra Swan's head is more gooselike, the bill appearing shorter than the Trumpeter Swan. The Trumpeter's bill appears longer and more elegant. Look at the angle we were mentioning before. The back edge in the Tundra Swan appears more vertical, versus more angled in the Trumpeter Swan.
         If you get a great look and can see the yellow spot, or the pink lip mark, or hear them call, by all means, make the most of these clues. But if the swans aren't making it easy on you, I hope you find these tips helpful.

Winter's Last Gasp, I Hope.

     It is getting so that I am so used to birding in the snow that I almost have a Pavlovian response to the sight of it falling - "Must. Go. Bird. Now." So, this morning, when I walked the dogs to the accompaniment of snow pellets bouncing off my jacket, it just seemed right to jump in the car and head to Wolf Lake Fish Hatchery. I found Trumpeter Swans at the hatchery, but also in an old corn field on 40th Street near M43, for a total of 5. Duck numbers are falling, but there are still good variety around. A remarkable 200 or so Tree Swallows were zipping back and forth over the big pond at WLFH.
     When I left the hatchery, I pulled into the boat access at Wolf Lake, across the street from WLFH. There I found this guy, who didn't seem all that troubled as I unloaded my gear and took a few pictures.

    There was also a Pileated Woodpecker, some Common Mergansers, and a few Blue-winged Teal present there.
     At Maple Lake, most of the ducks have dispersed or moved on, but there was still a breeding plumaged Common Loon and a breeding plumaged Horned Grebe present.
     If you'd like to join me as I try not to miss any of the wonders of spring in Van Buren County, we will be meeting at Wolf Lake Fish Hatchery's parking lot on Monday, April 15, at 10 AM. Hope to see you there!

Hard Core Birding

Somewhere there must be a rule written down that it must snow on Mondays at Wolf Lake Fish Hatchery! Today the snow wasn't much to speak of, but the wind briskly kept us company throughout our visit. Duck-wise, most of the mergansers were gone, but Canvasback numbers were up. There were only a few geese and we didn't see a single swan of any species. The ponds past the observation platform have been drained down since last week, and some Killdeer were foraging in the mud, along with some Mallards and a Green-winged Teal. In the second pond past the observation platform, a pair of Sandhill Cranes tolerated a fairly close approach as they fed, preened, and fended off some other cranes that thought to join them.

 

The wind followed us to Maple Lake, where I have come to expect it. By the bridge to Maple Isle, a bunch of coots were joined by a couple of  Horned Grebes in close to full breeding plumage. Duck numbers were way down around the island but we did see our first Ruddy Ducks, including a nice breeding plumaged male. The Ruddy Ducks flushed suddenly when a Common Loon came up from underneath them! We were almost as surprised, because that was our first clue there was a loon there at all.

There were still quite a few ducks on the lake on the east side of the road, including redhead, goldeneye, and a few red-breasted mergs. We didn't see any Hooded or Common Mergs today.
      Once again, the tea at the end of the outing hit the spot. I'd like to thank everyone who has been taking the time to come out and share the Van Buren County birding experience, including first timer Jean Ketchum today. The only thing better than being lucky enough to live in this amazing place is being able to share it with friends! We are planning to do it again next Monday. Eventually, I just know it is going to warm up! Check with me for details on time and meeting place. Until next time, bird on!

Gifts of the Earth

Sometimes the first few days of Spring feel like a series of presents from the Earth. Even though I am often just doing errands and not really birding, my mother taught me that it is rude to ignore an offered gift. So, this morning while I stood waiting for Shine the Whippet mix girl to finish her business, I got goosebumps watching a group of three Red-tailed Hawks soar over head, followed shortly by a Sandhill Crane. Then I was roaring down 38th Avenue on my way to Kalamazoo, when out of the corner of my eye, I glimpsed something white out in the corn stubble. Some quick action on the brakes and the letter R on the gear shift got me into position to see these guys. You can't really see the yellow spot on the bill in the photo, but it was obvious through binocs.

I did make it to Kalamazoo eventually, and on the way home decided to make a quick stop at Briggs' Pond in Paw Paw. Lucky for me, it is on the way! : ) In addition to a few coots, I saw a few of these guys - this one looked like he was just climbing out of his winter bed in the bottom of the pond.

Earlier in the week conditions were definitely more winter like. We saw this Sandhill Crane at Wolf Lake Fish Hatchery on Monday. You can barely see our first Green-winged Teal of the season facing away from the camera a little to the right of the crane.

And these Northern Shovelers standing on the ice at Three Oaks Ponds on Saturday were wondering what happened to the water.

Come to think of it, it feels like this week I had a front-row seat to the show I have been looking forward to all winter - The Coming of Spring. Don't change the channel now, folks. The show is just getting started!

Wolf Lake Fish Hatchery and Briggs' Pond March 18, 2013

     Four intrepid birders braved freezing temperatures, brisk winds and freezing rain today to bird Wolf Lake Fish Hatchery, Maple Lake and Briggs' Pond. At Wolf Lake Fish Hatchery, the usual suspects were joined by Horned Grebes. Only a single immature Trumpeter Swan was seen, but we didn't get to all the ponds. Our first three Tree Swallows of the year were cruising the ponds hopefully. A large mixed flock including American Tree Sparrows, American Goldfinches, Northern Cardinals and Song Sparrows was working the area around the maintenance garage, and while we were trying to get on a couple of Eastern Bluebirds, a small flock of waxwings landed in the top of a little tree only a short distance from us. We were thrilled to get scope views of the Cedars, as well as two Bohemian Waxwings.
     After this, we moved on to Maple Lake in Paw Paw. Once again, we found many Horned Grebes and all three Mergansers, as well as the other expected diving ducks. The lake is completely ice free now, so the birds have dispersed and views are much more distant than they have been.
    To wrap up our day we checked out Briggs' Pond at the end of Commercial Street in Paw Paw. Just as we decided there wasn't a whole lot going on, a Merlin zipped across the pond and landed on the tippy top of a dead tree, and waited while we all got great scope looks, and a so so picture.

       We parted ways agreeing that we had been well rewarded for our efforts, and eager to do it again soon. Yay, Spring! Bird on!

Signs of Spring

One of the local sign of impending spring is the appearance of the blue barrels on 45th Street. The old maples here have been harvested for their sap for many years.

Diving Duck Bonanza at Maple Lake

Oodles of diving ducks were concentrated at the north end of Maple Lake in Paw Paw today. This is the area where the boat launch ramp is located. The ice situation presently steers the birds close enough to shore for some excellent viewing opportunities. Common Mergansers, Hooded Mergansers, Lesser Scaup, and Redhead are all present, numbering in the dozens for each species. Common Goldeneye are also numerous, although less so than the others. There is still a single Ring-necked Duck hanging out here, as well as the ever present semi-domesticated Mallards, etc. I'd suggest that if you want to see these birds, you go soon. The next few days are forecasted to be warm, and the ice that is concentrating the birds will soon be gone.
