Thank you! Beautiful ferns!
somebody says the dog footprint is oval compare to big cat. Is it right?
Great info! I recently stumbled across this plant growing in a mulch bed while visiting a plant nursery . I dug a few up with their roots and took them home. I wanted to know if these will survive and are they invasive?
Wow. Very concise. Hope you make more videos on tracking.
No. While this seems to make a lot of sense, this little babe is wrong in not recognizing that there is a great deal of difference between breeds in their feet. She is presuming that in dogs the nails and the feet are somewhat splayed. In some breeds, such as Pointers and Shelties, round well-knuckled "cat feet" are considered a fault, but in others they are mandatory. For example, Dobermans. Giant and Standard Schnauzers, Bull Terriers and Akitas are described as “Feet well arched, compact, and catlike, turning neither in nor out.” Brittany standard even says that “An ideal foot is halfway between the hare and the cat foot." Some breeds of course have webbed feet, and they will obviously be more open. It is an interesting video, but there is a wide variety of feet in purebred dog breeds.
Thanks For the advice❤❤❤❤❤
Nice info thanx from pakistan
:)
Hi, today I was on a trail, it is 13C with snow melting all through the woods. I heard what sounded like frog sounds under the snow and my dog started digging like mad at that spot. I pulled him away and the sounds continued. A few feet away another spot was making the same sounds. Could they have been frogs emerging??
Good explanation- would have been good to mention the modern day vacuum system nullifies the need for the freeze/thaw cycle. My question- that no one seems to want have an answer- If there is no hole in the tree or freshly broken branch, does the sap move at all during “sugaring season”? Seems if it does, it would be raining sap in the woods because there’s not leaves to transpire the moisture. My thinking is - no, it’s just sitting there in the tree until the leaves bud out. Then there’s movement of sap within the tree. Thoughts?
Hello, I was curious about the potential affects to the trees if we tap during a warm winter, what with low water availability and a short freezing season
Great video! So informational. Thank you :)
Great and interesting video. Thank you.
Very interesting. Thank you!
This is very helpful and interesting. With this warm weather we've been seeing skunks on our trail cams (Leelanau county). One we see is mostly black and the other mostly white. Thank you for taking time to do these types of videos.
Wow that is really interesting. Thanks for the explanation!
I just found your channel and already halfway through your videos I saw you haven’t posted in a while hope you come back ❤
Love hearing those ovenbirds singing. ☺
How to soften the roots of Boston ferns so they can be removed
Can't wait to show this video to my kids! I always wondered about this!
How is this channel not more popular? This is great. Great host, very educational. Well done. I'm on a binge of your channel.
i wonder if they taste sweet haha
Thanks for the info
Which loop/trail might be best to try to get a glimpse of one of theses beautiful critters?

Stop yelling at me
You did a great job explaining this
I love her energy…as a St.Louis Cardinals fan - I thoroughly enjoyed this. Be well
Why are waterfowl(geese, duck) whether in feathers or webbing in feet never mentioned as a method of these snails hitchhiking. Many times how bass and other fish transfer from body of water to body of water.
Why wouldn't female cardinals be red for the same reasons?
Never knew they ate wasps..ever
With fronds like these…. 😂

Thank you , very informative 😊
A very well done tutorial. I am saving it for field reference. Thank you for your knowledge. 9:55
This was excellent! Thank you!

Coyotes are tracking my dog. I know the prints. Hind paws are smaller. I stay with my dog at all times. They refuse to let me see them. I know my dog's paw prints. They are cleaner than Wiley Coyote .
Fabulous video! While I knew there were coyotes in a field and forest beyond my house, I wasn't sure if the tracks I've seen recently were dogs or the 'yotes. I thought they were the coyotes, and every bit of this video confirmed it. Thank you!!
Thank you for this explanation, I was looking into refreshing the basics. However, the 'air bubble theory' has been disproven. Although it has an influence, the major mechanism is called the osmotic theory. See Cirelli et al. (2008) - Toward an improved model of maple sap exudation: the location and role of osmotic barriers in sugar maple, butternut and white birch
This was so informative and easy to understand thank you for your explanation and giving understanding to a miracle process that gives us such delicious syrup
Excellent explanation! I have always wanted to know how to identify pines v spruce and so on. Now all I have to do is be able to identify the species! 😊👍
Awesome video...! Great info. I am in Ontario Canada and a lot of species you talk about are here too!
Thanks for a great video. I'm loving your informative videos! Could you do one on prairie willow salix humilis ?
So cool! I'll have to look out for that one.
