Barred Owl
Here's a sound file. Barred Owls and Great Horned Owls apparently don't mix very well, so their territories tend not to overlap much. That would explain why I don't hear the Great Horned Owls this summer now that I'm hearing the Barred Owl.

Water Quality Sampling

The type of macroinvertebrates you find says a lot about the water quality. Certain types, like stoneflies, must have very high oxygen levels at all times. Other types, like blackfly and midge larvae, can live with very little oxygen and high numbers may be found in polluted waters (including my goldfish pond).
Because we volunteers are no experts, we pick one of every type of bug we find and place it in a jar of alcohol. HVA submits the jars to the DEP, who re-identifies everything in the jar and publishes a report. Here's the 2006 report.
The good news is that both streams are oxygenated enough to support a small number of sensitive species such as common stonefly larvae. The many waterfalls and riffles of both rivers is a big factor there. The bad news is that we are not usually finding many of the most sensitive species. Most of the bugs we do find -- netspinner caddisfly, fingernet caddisfly, midge and blackfly larvae -- are indicative of unnaturally high organic loads. Think lawn fertilizer and lawn clippings getting washed into the storm sewer.
For example, near Mill Street (Gristmill Trail), we collected 5 stoneflies (good), and also about 200 netspinners, 35 fingernet caddisflies, 1 fishfly, 2 snails, 3 riffle beatles and one small minnow mayfly. These are the bugs in the ice cube trays in the picture up above (click it to enlarge). Other Far Mill River samples were taken near Route 110 and off of Roaring Brook Lane. The sample near Route 110 looked better this year than the samples we usually get.
Here's a video from last year showing how we sample the river. Sometimes we get unexpected animals. The first year we caught a baby eel. This year we caught a baby salamander and a couple of fish (blacknose dace and tesselated darter).
Update 10/9/2007: A sample collected from Means Brook at Lane Street had none of the "most wanted" species, which suggests that oxygen levels are too low to support sensitive species.

Cannibal Frog
Yesterday I assumed the ruckus in my pond was another frog fight until I discovered our largest pond frog, "Bubba", with a pair of frog legs jutting from his mouth. According to Wikipedia, Green Frogs will "consume anything that can fit in its mouth, such as: crickets, flies, fish, crayfish, shrimp, grasshoppers, smaller frogs, tadpoles, small snakes, birds, mollusks, moths, and their own cast skin." I managed to grab my camera and get him on film just as he swallowed the feet (see below). Update August 14: Bubba was recently seen eating one of my goldfish, the tail hanging out of his mouth. This frog will eat anything that moves. Update October 2007, I've been told this one is a Bull Frog because it doesn't have ridges (see comments). If she's eating the Green Frogs, does that mean she's not a cannibal?
Green Frogs (Rana clamitans) are the classic pond frog in Shelton. Build a pond in your yard, and they will come in no time at all, adding a rather silly sort of charm to the pond. The males will puff out their yellow throats and starting singing only a few feet away from you, and they'll get into crazy frog fights. If you startle them, they yelp while making a comical leap.
Because most animals find their taste repulsive and do not eat them, the frogs are incredibly tame (my children have even managed to pet them on occasion). Dogs vomit after picking them up. Even the tadpoles taste bad. A few years ago I drained the level of my pond overnight to 6", with catastrophic consequences. By the next morning, the raccoons had reduced my goldfish and koi to nothing but a few scales. But the ground was littered with dead Green Frog tadpoles, each one having been tasted and then tossed aside.
They get so big that people often mistake them for bullfrogs. I frequently see them in our lakes, rivers, and puddles. The tadpole are also huge - several inches long, and they take over a year to mature.

Housatonic Coyotes



Giant Leopard Moth

A few years ago I ran across the larvae of this species - a huge wooly caterpillar off of Dominick Trail with distinctive red spots. It was so unusual I took it home to identify it.

Shelton Family Farm

The farm is located along the south side of Leavenworth Road (Rt 110) between the Monroe town line and Walnut Tree Hill Road, next to Jones Family Farm.
A couple of trout hang out in the brook


There is also a speedway, but that area isn't covered under the easement.

Shelton Beaver Mystery

Silent Waters Mystery Piers

For years many volunteers have pondered the row of paired stone & concrete supports located along the base of the Silent Waters dam (see photo). What were they? The dam was built in the late 1800's and burst in 1903, never to be repaired, so the supports were probably from the late 1800's as well. Mike Picone of Aquarion took a look at the pillars for me and stated what should have been obvious to us all: The piers held up a really big pipe associated with the reservoir. Of course! Reservoirs were (and still are) used for drinking water and there is an entire infrastructure related to transferring the water from the reservoir to the public.
I also took some photos today of yellow rocket and white baneberry in bloom at the base of the dam, and some views of Silent Waters on the new path at the top of the dam (see photos).

Gristmill Trail After Flood

I took photos of several types of our most impressive ferns: Cinnamon, interrupted and royal ferns; also spring wildflowers including wild geranium (my favorite), Jack-in-the-pulpit, and Canada Mayflower. No turtle nest, however! Snapping turtle eggs normally hatch in the fall, but may over-winter and hatch in the spring, and females may lay eggs up to 10 miles away, which sounds a tad ridiculous to me.

Letterboxing at Wolfe park

En route, we saw plenty of spring wildflowers, including red trillium, spring beauties (photo), and woodland anemones. And as we sat on one of the many benches along our hike we also got a good look at a pair of spotted sandpipers hunting along the shores of the stream that flows out of the lake. See photos.

Newts Stalking Their Prey
.jpg)
Oddly, red-spotted newts have two forms, the aquatic one (shown) and the bright red terrestrial form called the red eft. They start out as the aquatic form as babies, then switch to the red terrestrial form for a few years as adolescents, so to speak, then revert to the original form as full adults. I was watching the adults.
I once hatched salamander eggs and the baby salamanders voraciously ate mosquito larvae, which we had to raise in a little pool out back. The salamanders creep up very slowly, and as soon as one of the mosquito larvae wiggle in their face WACK - no more mosquito. A salamander can probably eat hundreds of larvae each day. While you're sitting there, tadpoles or maybe salamanders will suddenly lunge to the surface to gulp some air. You never get to actually see them, just the disruption they make at the surface.
I also got a photo of a rufous-sided towhee, which are common along the powerlines.
