The birds were hanging out in good numbers at Sapsucker Woods this morning, and were decorating the trees like Christmas lights when seen via the Therm-App.

| Mourning Doves in the left, Cedar Waxwings in the right. Not that I expect to be able to tell species apart with a thermal imager. |
Meanwhile, I found this interesting warm spot in the woods:
The thermal image shows a slice of the tree back being warmer than the rest of the tree. Is this from rot? A cavity? Something else? I did not pry to find out. (Experience has also shown that tree cavities usually register
colder rather than warmer than the surrounding wood, unless, of course, there is some warm inhabitant within.)
Interesting...what is the temp diff? a few degrees?
ReplyDeleteThe tree trunk read around 0.3C, the warm slice around 0.9C. Not a big difference.
