The day prior to the huge blizzard last week I finished up my work building BirdNET-Pi birdsong listening stations for three nature centers located in northeast Minnesota’s Boreal forest wilderness. All three stations are now live and listening, and you may check out and listen to the birds each station heard over the past 24 hours (or pick your own preferred time period). Each nature center is located within microphone listening distance of unique Boreal forest, lake and pond habitat

Select any one of these links to hear what birds are singing: (using a desktop or laptop computer for listening works MUCH better than a mobile device … learn more from a prior post of mine which also links the other listening stations)

• Boulder Lake Environmental Learning Center (a bit north of Duluth)
• Chik-Wauk Nature Center (end of the Gunflint Trail)
• Sax-Zim Bog Welcome Center (on Owl Avenue on Sax-Zim Bog)
• No account is required to listen

I look forward to a continuing relationship as a volunteer for each of these organizations. As the snows melt this spring these stations, including some other stations located right on the North Shore of Lake Superior will provide a unique perspective of the northward bird migration status. I donated my time, knowledge and the entire cost of these Raspberry Pi Computers.

Some of this year’s research includes:

• Bird Song academic curriculum development for children & teachers
• Nesting sounds of the Common Loon parents and chicks
• Identification of Connecticut Warbler habitat
• ReUse or Not of Great Gray Owl Territory

This work also involves off the grid listening stations.

This is the second in a series of posts about the my new Rix Pocket K3 with a native resolution of 384 x 288 thermal sensor.  This resolution is one step up from the more basic 256 x 192 thermal sensors. All posts will be linked to my initial post. Like all equipment reviews features on my website, I purchase everything with my own money and NEVER accept or seek paid endorsements. (browse to the first post in series/review with subsequent linked posts).

It is too early for me to form an opinion yet about my new thermal monocular. My sole purpose with this post is to provide my first efforts with the monocular taken by a beginner who really has no idea what he is doing.

First Day’s Outing With Thermal … Up at the Greenwood Creek Birdfeeders in northern Minnesota …. habitat is deep wilderness where I maintain trailcams, listening stations and birdfeeders deep in the Boreal Forest. I was using “Red Hot” for this initial test.

Image (the “red blobs” are chickadees and blue jays. Video was taken from a distance of about 50 yards right before sunrise)

Second Day’s Outing With Thermal … Near my home in northern Minnesota …. habitat is deep white pine forest with a stream that flows down to Lake Superior which is about 1,000 yards distant. I was using “White Hot” for this test. The image and  video were taken 60 minutes before sunrise. It was pitch dark out, and I could not see the owls on my own. The temperature outside was 28F.

Image (The owl was behind the white pine’s trunk, and I could not pick it up with my new thermal. The only reason I figured out the owl was behind the trunk was because moments later it hopped out onto the branch … the movement was extremely obvious. See the video.)

Video (link for blog email subscribers)(The Great Horned Owl may be seen towards the middle bottom of the video. I believe it is the female who I named Amy many years ago. I have the monocular on its lowest, basic magnification (2x optical). I rarely zoom while scanning for two reasons: 1) I want as wide a field of view as possible for trying to locate birds. 2) Digital zoom on any device degrades the optical quality in my opinion)
