How Birds Stay Warm in Winter - And How to Help Them

For the last few days it has been exceptionally cold here in Maine. Birds and squirrels keep showing up at our bird feeders despite the cold or perhaps because of the cold. While looking at the birds at our feeders yesterday my youngest daughter asked how the birds stay warm enough to not freeze their feet. It was a good question and I found the answer in this short BirdNerd video.  

By watching BirdNerd's How Birds Stay Warm in Winter video my daughter and I learned that some birds can regulate the temperature of their feet separately from the rest of their bodies. Watch the video to learn more about that and other ways that birds stay warm in the winter. 

There are other things you can do to help birds in the winter besides putting out bird feeders and keeping them full. Those things are explained to young students in the SciShow Kids video titled How to Help a Bird.

How to Use SVG Files in PowerPoint

Last week a reader reached out to me for advice about how to design slides and PDFs so that the images in them didn't get grainy-looking when they were enlarged. The solution that immediately came to my mind was to use SVG files whenever possible instead of JPG or PNG files. SVG stands for Scalable Vector Graphic. 

An SVG won't get grainy when it is enlarged for use on a slide or PDF. In the video that is embedded below I demonstrate how to use SVG files in PowerPoint and Canva. In the video I also show a couple of places to find SVG files.
