The past few days while camping at the National Forest Service Pfeiffer Lake Campground, I 

heard a buzzy warbler song that stumped me.  I knew it wasn't the Black-throated Green 

Warbler or Black-throated Blue Warbler as I had a lot of recent exposure to those at 

Temperance River State Park and Oberg Mountain in the last week.  The song is 4-5 faster 

buzzy notes ending in a higher singular buzzy note.  It wasn't until Roger Schroeder's post 

about the Cerulean in Lyon Co. that I started to study that song.  It seems to my wife and 

me to be a match to what we heard.  



 I hesitate to post this as I'm not 100% certain and have not got a good look at the bird 

despite much effort. I have seen enough to know it's a warbler-shaped bird. This bird sings 

from the very tops of 30-40 ft tall aspens and birch trees.  Its territory is an open stand of 

birch and aspen immediately to the north of the campground host. It can also be found 

along the east-west road to the north of the host near the area mentioned earlier.



I'm posting this in case someone local wants to check it out and confirm or deny the 

presence of a cerulean before people make the trek.  I am running out of time to check it out 

as I leave tomorrow.  Pfeiffer is on MN Hwy 1 at mile marker 254.  It's about 5 miles west of 

the Y store in Tower. 



While hunting this mystery bird I observed a nesting pair of Blackburnian Warblers, singing 

Northern Parulas, Gray Jays, and an Eastern Kingbird.  I also heard a Black-throated Green 

Warbler.  It should be good birding even if this bird isn't a cerulean.



If you have other possible species it could be, let me know.
