Back to the Beaver Pond

It was a truly lovely evening for the last week of summer: clear, cool, with a gentle breeze. So back to the nearest beaver pond I went hoping for a few photos of the resident beavers. The pond is about a quarter acre in size, but with connections to much larger wetlands.

These beavers are “bank beavers” that haven’t built a lodge of sticks and mud as do most beavers that inhabit ponds or lakes. Instead they dwell in a large, possibly intricate, burrow in the bank of the pond. Why these beavers, who have been here for a number of years, have never constructed a lodge is a mystery to me.

After I’d sat by the edge of the pond for about 45 minutes, a male wood duck in “eclipse plumage”, approached –

He saw me, realized something was amiss and swam away.

It wasn’t long before the first beaver appeared –

And then there were two –

They patrolled the pond before going through the oversized culvert that gives them access to a much larger pond/wetland complex –

They left, the sun was setting, and it was time for me to leave as well.

**********************************************

Twenty-two hours later, on a very similar evening, I was back at the beaver pond. Once again the first thing I saw were wood ducks, including a male standing on the branches of a fallen tree –

But I was after beavers and from the place I chose to sit the wood ducks were no longer within view. As I waited, a female common spreadwing damselfly was nearby laying eggs on a blade of grass –

The first beaver, an adult, appeared shortly after I arrived; 40 minutes earlier than the night before –

It went through the culvert and I sat waiting; wood ducks soon made an appearance. First a lone male and soon two females –

Then came another beaver, a yearling, followed by another adult –

A few minutes later the prize of the evening popped to the pond’s surface, this year’s beaver kit with frizzy hair similar to that often seen on human teenagers –

All the beavers apparently swam through the culvert to the larger wetland.

Beaver lodges or bank burrows are usually occupied by a pair of breeding adults that mate for life, the one-year old yearlings that will leave the colony in late winter, and the current year’s kits.

As a solid bank of clouds began obscuring the sun, the final beaver of the evening appeared, another yearling which also swam through the culvert to the larger wetland. The light had really dimmed, so it was time to pack up and head for home.

Small and Large

The day dawned cloudy and hazy and extremely humid but it wasn’t too hot and there was a pleasant breeze. And so I decided to take a longer walk than I’ve taken in over a year and headed to a state game land. Since the Pennsylvania Game Commission (PGC) is responsible for all birds and mammals in the state, I believe the name should be “Pennsylvania Wildlife Commission” – but it’s not and the land the PGC manages are called Game Lands. Those names make it appear that the PGC’s allegiance is only to hunters.

In any case, game lands harbor all sorts of wildlife from tiny insects to bear and elk. This day in mid-summer, when bird song has essentially ended, the only wildlife that’s really active are the hordes of insects of various sizes and lifestyles.

So it’s no wonder that butterflies were some of the first things I photographed that day, especially because many butterflies are quite photogenic, even the very small least skipper.

Some of those butterflies were feeding on nectar in the abundant teasel flowers. Teasels were introduced to North America for use in the textile industry to raise the nap on woolen cloth and make the cloth softer and warmer. While that use has been displaced by machinery, the species remains as an invasive plant in old fields and pastures where its flowers feed butterflies –

Even more abundant were the bright yellow flowers of thin-leaved sunflower –

I was walking a long loop that took me past several wetlands. One of those wetlands had a large assemblage of greater bladderwort in bloom. Greater bladderwort is a small carnivorous plant that lives in shallow water and captures tiny aquatic creatures in inflatable bladders on its roots and stems and has interesting yellow flowers –

Among the other small things to be seen that day were two species of damselflies; first the fragile forktail and later the eastern forktail –

And suddenly the largest critter of the day flushed from a tall white pine – an adult bald eagle –

With that it was but a short walk back to the car.

Hummer

Ruby-throated hummingbirds in the northeastern U.S. feed on the nectar produced by a fairly small suite of wildflowers: cardinal-flower, spotted jewelweed, wild bergamot, trumpet creeper, wild columbine, several milkweeds and a few others. Most of these plants grow in small colonies or as scattered individual plants.

Because their primary food sources are usually either limited or scattered or both, these hummingbirds aggressively defend “their” flowers from other hummingbirds. Those of us who have hummingbird feeders filled with a sugar/water mixture have created new “flowers” that bloom continuously and have an unending supply of “nectar”. But the hummingbirds don’t know that these “flowers” won’t stop blooming in a few days as wildflowers typically do, so they often defend them just as vigorously.

An adult male ruby-throated hummingbird has taken possession of the feeder hanging outside our kitchen window. The bird’s found that a dead branch mere feet from the feeder is an ideal spot from which to watch for interlopers. The branch is the place from which he launches attacks on any hummingbird that approaches the feeder.

It was a cloudy, drizzly, occasionally rainy day when the male hummingbird perched on the dead branch for quite a while. That gave me the opportunity to photograph him as he repeatedly turned his head, displaying the gorget on his throat as its feathers reflected various colors depending on the angle of the light –

The concept of sharing is obviously not part of this hummer's world. 

Soon all the hummingbirds, whether they use our feeders or not, will head south for the winter. Some making a non-stop flight across the Gulf of Mexico, until then the feeders will help them to store energy for the flight ahead. 

Butorflēoge

The word "butterfly" apparently comes from the Old English word butorflēoge, the butterfly; similar words in Old German and Old Dutch lead to the conclusion that the name dates to antiquity. Many believe that the name originated because butterflies were flying in pastures during the spring and summer when the grass was lush, cows gave a lot of milk and the winter’s supply of butter was produced from the abundance of milk.

There are competing theories about the origin of the word butterfly, but wherever and whenever the word originated, few would deny that butterflies are beautiful creatures.

As with many insects, butterflies have a somewhat complex life-cycle. Impregnated females lay their eggs on the food plants that the larvae prefer. When the eggs hatch the larvae feed and go through several stages (instars) as they grow, shedding each time. As the larvae finish their growth they pupate in what’s known as a chrysalis, they then metamorphose and emerge as butterflies.

Many butterfly species spend the winter in the egg stage, some as a chrysalis, some hibernate as adults and others actually migrate. The monarch is the best known, but not the only, species of butterfly that migrates.

Enjoy the beauty of butterflies –

Yes, enjoy the beauty of butterflies for as the weather cools and winter approaches butterflies will disappear from the meadows. Habitat loss from intensive agriculture, manicured lawns and industrial development means there are fewer butterflies each year – enjoy them while you can.
