Eastern Chipmunk

Here's an Eastern Chipmunk I met last autumn. The little guy was near a hollow log though it's unlikely the chipmunk lives there. Despite being skilled tree climbers, chipmunks like to live in burrows in the ground consisting of several tunnels. (It's possible there's a tunnel entrance under the log, I suppose.)

Chipmunks are omnivores that primarily eat vegetation but will eat some invertebrates and even bird eggs and small bird hatchlings.

It's a little difficult to describe how they spend the winter. Some sources have said they're too small to store enough body fat to hibernate through a winter, while others say they are hibernators. Maybe the key is that sometimes the term hibernation means essentially sleeping through the winter and sometimes means hunkering down in a den with food and periodically eating a meal. My guess is that Eastern Chipmunks hibernate in the sense that they mostly sleep but occasionally snack during the winter.

Tussock Moth Herd

Image
Some caterpillars are usually seen in large numbers (like Armyworm Moth caterpillars and Eastern Tent Caterpillars ), while most are more solitary. The Milkweed Tussock Moth caterpillars (more about them are here ) seem to be slightly social. I'll sometimes see them alone, but more often I'll see them in groups of 2-9 members. In the 1st picture below, you can see there is a clear size difference in some of these individuals. I'm almost certain the little one in the middle is in an earlier instar than the others (though they lack the colorful tufts of fuzz in their earliest instars).

Eastern Pondhawks

I'm going to try something different today with my Eastern Pondhawk pictures. I'm going to let ChatGPT do my blog today. (ChatGPT is an AI program that you can converse with in a pretty human way; an explanation of it is here .) Me:  Can you tell me something interesting about the Eastern Pondhawk? ChatGPT:  The Eastern Pondhawk (Erythemis simplicicollis) is a dragonfly species that is native to North America. It is a medium-sized dragonfly, with a wingspan of about 3 inches, and can be found in a variety of habitats, including wetlands, marshes, and ponds. One interesting characteristic of the Eastern Pondhawk is its mating behavior. Male Eastern Pondhawks are known for their territorial behavior and will defend their territory from other males. They will patrol their territory and will try to mate with any females that fly into their territory. Another interesting fact about the Eastern Pondhawk is that it is a fast flyer and is able to hover in midair. It is also an impor...

American Bullfrog

Image
Though I got some pictures of Wood Frogs earlier in the season and had been hearing the small/elusive Spring Peepers about that time, it was only about 5 weeks ago that I started seeing one of our most visible frogs, the American Bullfrogs . I've talked before about how to differentiate them from their Green Frog cousins (hint: it's all about the dorsolateral ridges), a fairly similar frog that starts appearing about the same time of year. This wasn't my first bullfrog picture of the season but was one of the most handsome. I think they tend to look a little discolored and emaciated very early in the spring. A few weeks later they seem to regain their plumper and greener appearance.
