Wisconsin Warblers

Recently, I just took a trip to Washburn County, Wisconsin, with my family.  We stayed just outside of the Spooner and Shell Lake area in the town of Bashaw.  The trip was mainly a trip for working on a project with my family, so I didn't have much time for birding.  But the birding that I did have, turned out to have some very epic sightings and enjoyment of eastern North America.  With as much of my life that I have lived in Arizona, it's always good to get out of the southwest and to see and learn more about eastern North America.  Washburn County, which is situated in northwestern Wisconsin, is a great place to learn about and see a variety of eastern birds.  When visiting this region, eastern warblers often catch my attention more than other birds.  Why?  Because they are awesome.  Before the trip, I jotted down a total of 9 potential lifers that I could land in the Washburn County section of Wisconsin.  With as much work as my family and I had to do, I knew that I would be lucky to make it to more than several Washburn County spots of my choice, yet alone leave the small county to bird Wisconsin elsewhere.  The 9 lifers I had a chance at were Blackburnian, Canada, Mourning, and Connecticut Warblers; Black-billed Cuckoo, Alder and Yellow-bellied Flycatchers, Blue-headed Vireo, and American Woodcock.   Before the trip, I said that 4 to 5 lifers would be solid out of the 9 possibilities.  We departed Phoenix on a Southwest Airlines flight on June 24th, and would be in Wisconsin for working until July 1st.  Before we would work, I had a few hours for birding every morning.  And sometimes, I would have times to go at different times of the day after we finished sections of work.

From the get go, the start of the trip had warblers written all over it.  Appropriately so, the epic warblers deserve their own blog post.  Right away, I heard an Ovenbird, a warbler that is fun to watch, observe, and listen too.  It took me awhile to see an Ovenbird, but I did have a spectacular view of the Yellow River from my Aunt Gretchen and Uncle Larry's cabin.

At one of our first stops to do the house work, I got to see a few "Myrtle" Yellow-rumped Warblers.  I don't see enough of these birds, and seeing them on territory for the first time revealed a neat bird.  This bird was in talks to finally be split from "Audubon's" Yellow-rumped Warbler, but the split apparently didn't go through this year.

When the mornings started, I would wake up and go birding.  Birds were everywhere around the cabin in mixed woodlands that were dominantly deciduous with some stands of pine.  After some patience, I did get some visuals on that Ovenbird.  Ovenbirds can be hard to phish in as opposed to other warblers, and sit deep in the forest.  But when one is seen, it will often stand still and sing before walking across the limb to repeat the singing process.  It is a behavior that is enjoyable to watch and despite the fact of how common Ovenbirds are in eastern North America, I don't think I could grow tired of this bird.

As I walked along the roads near the cabin, I quickly saw that there was a lot of second growth forest in front of the taller and more mature forests behind it.  Most of the second growth forest would be right along the roads in the area, which were called Hector Dam, Loop, and Greenfield Roads.  These three roads saw me almost daily during the course of our stay, and they held perfect habitat for the next warbler I'll feature, which is the Chestnut-sided Warbler.  Prior to this trip, I had never seen this species in it's breeding plumage, and Arizona has given me a handful of non-breeding CSWA's.  But for the first time, I got to see the true Chestnut-sided Warbler.  It was very common near the cabin and throughout Washburn County on the trip, and I stopped to look almost everyone of them I saw.

Golden-winged Warblers are a declining species throughout their range, largely due to hybridization with Blue-winged Warbler and having their habitat also taken away by Blue-winged Warbler.  On my trip to Wisconsin, Golden-winged Warblers were extremely common.  They prefer second-growth forests as their habitat, especially when there are small stands of aspen in the area.  I couldn't go anywhere on my trip without seeing or hearing them.  At one point, I heard their closely related Blue-winged Warbler cousin also singing nearby.  After seeing this bird in central Wisconsin last year for my life bird and then discovering a vagrant in Gila County, Arizona this year, it was great to add this one in abundance and really get a fill of them.  Wisconsin is probably the premier state to see this species in North America.

A high pitched trilling song up at the summit of pine trees reveals the rather plain-colored Pine Warbler.  This species is well named, as it is almost always tied to pine trees.  Vagrants and wintering birds are the same way, as they seek out parks or cemeteries with such planted evergreens.  In Wisconsin, I constantly had a few Pine Warblers around the family cabin.  And a few times on the trip, I got to see them despite their life high up in pines.

On June 25th, 2017, it was our first full day of the trip.  I had a few hours to walk around the cabin and bird before our workload began for the day.  A harsh chipping callnote that I was wanting to hear came from the dense habitat nearby, and it was that of a Mourning Warbler.  After some phishing, it didn't take very long for a female Mourning Warbler to pop up.  She was shortly joined by the male, who then burst into song shortly after.  Mourning Warblers are set apart from very similar MacGillivray's and Connecticut Warblers by their lack of eyerings and black-breasted males.  Female Mournings do show white eye arcs above the eye, while any sort of white around the males eye is rare.  Well, my lifer Mourning Warblers here both seemed to have an above average amount of white around their eyes, which was interesting.

Mourning Warbler was my first life bird of the trip, and it was great to get them early.  They prefer dense undergrowth within forests and like their MacGillivray's Warbler cousin, they are quite skulky and can require patience in order to get great views.  I will say though, throughout the rest of the trip, the Mourning Warbler continued to be good to me.  There were many more of them who I crossed paths with.

Black-and-white Warblers have an obviously appropriate name.  They also are distinctive for a warbler, not only for their color, but for their nuthatch-like foraging behavior.  Big tree trunks in mixed forests in the east are what these warblers need, as they pursue prey in nuthatch fashion.  As I walked through the woods throughout Washburn County, Wisconsin, the high pitched song of the male Black-and-white Warbler was everywhere.  It was the first time I got to see this warbler on it's territories, and it often came into view for me.

Redstarts are crowd pleasers with their acrobatic foraging motions and their constant behavior of fanning their tails.  Last year in Minnesota, I got to see many American Redstarts on territory for the first time after seeing a handful of birds in Arizona, most of which were dull-colored females or first year males.  This year in Wisconsin, I got to enjoy many American Redstarts to follow up Minnesota.  Almost all of the American Redstarts I found on this trip were adult males with the exception of one female, who were all most likely away nest tending.  American Redstarts often forage at mid to low-levels beneath tall forest canopies.  While the observers of these epic birds often think they fan their tails for show, it is really used to flush insects.

Warblers were commonly carrying food in their mouths during the course of many of my observations.  They had young ones and mates to feed.  Another common warbler around was the Nashville Warbler.  This is another first time I've seen of a warbler on territory.  This is one that I often see in fall migration in Arizona.  Nashville Warblers were very common during my birding in Wisconsin, but were difficult to photograph.  However, one of them gave me a decent shot.

The Yellow Warbler is a common warbler in a variety of habitats throughout North America, and is one that is commonly an eye catcher by those who aren't into birding.  After all, they commonly show up in backyards and gardens.  Because I see this warbler a lot, I didn't try to photograph it very much.  And then something interesting happened.  While I was near the Yellow River, I noticed two Yellow Warblers feeding in the road, and one of them wouldn't move and was seemingly tied to the ground.  Even when I tapped it, it still wouldn't move.  I decided to pick the warbler up and search for a safe place to put it where it wouldn't get flattened by traffic.  As I was searching for a spot, my family came down the road.  Intrigued by the warbler, they took many pictures of the bird in my hand.  After the family fun, I tossed the warbler in the air and it flew to a nearby perch.  It seemed healthy but a bit stunned by something, hopefully it continued to live.  The picture of the bird in my hands was taken by my cousin Dylan.

Other warblers seen or heard that I couldn't and didn't photograph were Common Yellowthroat, Blue-winged Warbler, and Northern Waterthrush.  The Common Yellowthroat was the most common warbler in Wisconsin during my time here.  It's common here too, which is why I didn't spend time trying to get photographs with all the sexy eastern warblers around that I rarely see.  Blue-winged Warbler was heard once on private property and Northern Waterthrush was heard singing three times on different spots along the Yellow River.  Blue-winged Warbler and Northern Waterthrush I would have loved photographs of.

And wait, we aren't done yet.  I saved the best for last!

On June 27th, it was more of a laid back day at Gretchen and Larry's cabin.  At a point where much wasn't going on in the afternoon, I was around the cabin and I said to my Aunt Tracy how much I wished there was a vehicle for me to rent so I could run around where I wanted to.  She told Gretchen and Larry about it, and with their generosity, they lent me their vehicle for the remainder of the day.  I headed straight for the northeastern part of Washburn County, just north of a small town called Stanberry.  There were many birds I was targeting here.  Three of them were life warblers:  Connecticut, Canada, and Blackburnian Warblers.  This side of Washburn had more solid coniferous forest than the rest of where I had birded on the trip.  I started searching for Blackburnian Warbler at a bog area where a guy had them last year.  Due to wind and time of day, there weren't very many birds that were active.  I stepped a few feet into the spruce bog, and I will say I won't do that again without rubber boots.  While I didn't have luck at this bog, I went back to a bog that was roadside on County Road M just north on Stanberry.  I still didn't officially enter this bog, but I was sure glad it was so close to the road.  And birds were everywhere, warblers included.

Once walking along the bog, it wasn't long before I succeeded and landed one of my highly wanted targets, my lifer Canada Warbler!!  It was a female Canada Warbler, and they aren't as awesome as the males, but are still awesome.  Canada Warbler is extremely rare as a vagrant in Arizona, and is one I've always had in mind as a warbler favorite.  They are quite a skulky species, and they like low and thick understory within mature forests.  This female gave me a few great looks, as well as photo opportunities.  She remained skulky much of the time though.  After wanting to see this species for so long, it felt great to finally land it as a lifer, and my second lifer of the trip.

After the fun with the female Canada Warbler, I felt a little greedy and wanted to see a male Canada Warbler, who is striking with a bold black necklace in comparison to the females faint necklace.  More than that male Canada Warbler, the warbler I wanted to see most, the Blackburnian Warbler, was now dominating my mind.  I walked further south along the road at the edge of the bog along County Road M.  When I came upon the end of the bog, there were some wetland areas that held many dragonflies.  I photographed some of the odes until I heard the freaking awesome song of the Blackburnian Warbler himself.  It was back in the bog a bit.  The song is a trill that gets higher and higher in pitch with a very high pitched notes to close out the song, very distinctive.  Excitement was at it's high.  And after a few minutes, the male Blackburnian Warbler emerged from the conifer-filled bog!

The Blackburnian Warbler may just be my favorite warbler.  It reminds me somewhat of our Red-faced Warblers here in Arizona, except is has a fiery orange head and throat.  The striking features are similar with those two birds.  I looked up and the bright orange stood out like no other.  A fire had been lit!  Blackburnian Warblers are much of a northeastern warbler, and prefer mature coniferous forests as their main habitat choice.  A spruce bog, such as where I was birding, is perfect habitat for them.  As I drove down County Road M, I immediately thought it looked good for my targets.  And an hour after I first drove through it, I was sure glad I returned and had locked up Canada and Blackburnian Warblers.  The Blackburnian is one that is often thought of as a tree topping warbler.  Thankfully, this one was much lower than the tree top and it put on a show for me!

After the male Blackburnian flew back off into the bog after a few minutes of my cloud nine observation, I went birding for a short distance on Sugar Bush Road, which branched off from County Road M.  When I came upon a turn on the road, I could see and hear a lot of warblers.  It was freaking awesome.  I started pishing away and I quickly attracted 9 different warbler species.  It was simply incredible.  Warblers that flew in were Ovenbird, Golden-winged Warbler, Black-and-white Warbler, Nashville Warbler, Mourning Warbler, Chestnut-sided Warbler, Pine Warbler, Yellow-rumped Warbler, and that adult male Canada Warbler that I was greedily wanting to see, and photograph....

My North American warbler list is at 44 species now.  These birds are one of my favorite families and commonly steal the show.  The warbler target I missed on this trip was Connecticut Warbler.  I hope to return soon to Wisconsin or Minnesota to try for that and also, Cape May Warbler too.  But Blackburnian Warbler and Canada Warbler seen in the same hour as life birds, that feat may be very hard to beat.  Thanks to Uncle Larry and Aunt Gretchen for making this happen, and thanks to Aunt Tracy for telling them how much I wanted a vehicle to drive.

Stay tuned for more Wisconsin birding posts.  There were other birds outside of warblers, lots of them actually..

  1. The Blackburnian is a true prize--I'm glad you got it! I never tire of them and I think I photograph everyone I see.

    The first CSWA shot is my favorite because, even though the bird is a small part of the pic, you can see all the striking field marks plus you can see it in its ideal habitat of young Aspens.

    Congrats on the Warbler lifers, Tommy!
