On a bird walk during the first week of summer I was able to see American redstarts, red-eyed vireos, yellow-throated vireos, pileated woodpecker, Eastern peewee, hermit thrush, ovenbird, veery, great crested flycatcher, and scarlet tanagers singing on Crusher Rd. near the old quarry, where I hear them every summer at that same spot. Wood thrushes were also heard near the trailhead. Though I can hear hermit thrushes throughout the park for most of the summer, wood thrushes tend to be heard sparsely, and mostly near the trailhead area.

On July 1st, I planted milkweed seedlings, as I do every year, in the area where the old beach used to be during the early 1950s at Rocky Pond. The area has been designated a Monarch butterfly Waystation and provides migrating Monarch butterflies with food, and a place to lay their eggs as they migrate southward.

On that same day, I planted some two dozen Buttonbush seedlings along the shores of Rocky Pond as part of a project to attract more waterfowl to that pond. Buttonbush is an impressive-looking flower that produces a prodigious amount of seeds that waterfowl feed upon.

Also on this day, I noticed that an extraordinary number of young Eastern chipmunks were scurrying about the forest floor. I’m guessing that it was the second litter I was seeing.

During a July 4th walk, I was able to see crows, hermit thrushes, red-eyed vireos, veery, Eastern peewee, American goldfinch, broadwing hawks, ovenbird, blue jay, hairy woodpecker, yellow-bellied sapsucker, osprey sitting on their nest at Muddy Pond, and Eastern phoebe. The infestation of gypsy moths had tapered off, red efts and mushrooms were seen in big numbers due to recent rains, and many plants were in flower including forget-me-not, common mullein, ox-eye daisy, common fleabane, cow vetch, yarrow, common St. John’s-wort, hop clover, common milkweed, red clover, tick trefoil, heal-all, poke milkweed, whorled loosestrife, black-eyed Susan, rough-fruited cinquefoil, and ladies tresses. White admiral and Great Spangled Fritillary butterflies were also seen.

During a mid-July walk, I observed an Eastern chipmunk being chased off a tree by an Eastern kingbird. Though I did not see a kingbird nest, I have no doubt there was one nearby. Purple loosestrife was in bloom at Rocky Pond, and the American chestnut tree on Svelte Tiger had male catkins in flower. Female gypsy moths were found on many trees laying eggs, with many males flying about looking for females to mate with. I was happy to see Eastern phoebes and Eastern kingbirds catching male gypsy moths “on the fly” then devouring them.

Using my bird call “app”, I was able to call in a scarlet tanager and have it land on a branch just a few feet away from me. What a magical moment. Along the south shore of Rocky Pond, I was able to see a cedar waxwing and ruby-throated hummingbird fly in and out of their nests. It’s amazing how small the hummingbird nest is in size. Also saw a hummingbird clearwing moth feeding on the nectar of milkweed flowers. Its size and flying behavior cause it to sometimes be mistaken for a hummingbird.

On July 16th, I was treated to the sight of two young barred owls perching on the limbs of a  white pine tree, near trail marker #16. One of the birds allowed me to approach within just a few feet. I kept looking for the mother nearby, but she was nowhere in sight. Another magical moment.

On the way back to the trailhead, I came across a most beautiful white-tailed deer doe. White sweet clover, Queen Anne’s Lace, cow-wheat and common agrimony all in flower. The Common Wood nymph and northern crescent butterflies were flying about.

A week later, I came across young barred owls once again in the same area. But this time, there were 3 young owls! For years, I’ve been hearing barred owls “hooting” in that area, but have never found their nest. Maybe next year?

During the last week of July, I took a hike up to Muddy Pond to take a closer look at the Osprey nest. One adult was on the nest, at least one young was in the nest, and another osprey adult perched in a nearby tree. It would be the first and last time I saw any signs of the young osprey, though I heard reports from others that 3 ospreys could occasionally be seen at Muddy Pond in late summer. On the walk back, I saw an Eastern garter snake and young pickerel frog near Rocky Pond.

On an evening hike during the first week of August, I noticed a couple of interesting things. First of all, the forest was relatively quiet, and secondly, I didn’t see a single male gypsy moth flying about. Our local birds were having a feast there for a few weeks. The ruby-throated hummingbird was no longer sitting on its nest, and both bullfrogs and green frogs could be heard “croaking” at Rocky Pond.

By mid-August, chipmunks and squirrels were busy collecting acorns, blackberry shrubs were in fruit, and Eastern towhees were singing in the same area they are always found underneath the power lines on the Carriage Trail as you head up to Rocky Pond.

On Aug. 21st, I, and members of the Rutland Co. Audubon Society, had the privilege of going on a fern walk with Emeritus Professor of Biology at St. Michael’s College, Peter Hope. We saw lady fern, ostrich fern, sensitive fern, intermediate wood fern, cinnamon fern, Christmas fern, hay-scented fern, New York fern, maidenhair fern, marginal wood fern, bracken fern, and interrupted fern. VT has a little over 60 fern species, and many can be found at Pine Hill Park.

During the last week of August, I saw white lettuce, whorled wood aster and the beautiful dark-blue colored bottle gentian, all in flower.

The forest during the first week of September was very quiet. Just a few birds were seen on an evening walk, including the white-breasted nuthatch, hairy woodpecker, and a great blue heron at Muddy Pond.

On a Sept. 6th walk, I was treated to the sight of a majestic Bald Eagle flying over Muddy Pond, a few wood ducks, one osprey, and a great blue heron. Cones were maturing on Eastern Hemlocks, acorns were falling(one fell on my head!), Jack-in-the-pulpit had mature bright red fruits, and silverrod, New England aster, and goldenrod were all in flower.

On Sept. 11th, the forest was once again very quiet. Acorns were still falling, chestnut-sided and black-and-white warblers were migrating through the forest, hooded mergansers were seen at Rocky Pond, and a great blue heron, a few Canada geese, and wood ducks, and three active beaver dens were seen at Muddy Pond. A few trees were starting to show fall colors.

On Sept. 16th, many robins were seen migrating through the forest, chipmunks and squirrels were busy collecting acorns, and a Northern flicker was seen.

That’s it for this issue, please enjoy your walks at Pine Hill Park, and remember to stay on the trails.

Wild Times at Pine Hill Park
Spring, 2021 Summary

By Tom Estill

I always make a point of going on hikes throughout the forest during the first day of each season. On the first day of this spring I saw my first robin. They always seem to arrive at Pine Hill Park on, or very close to, the first day of spring. What I’m wondering is if this will be the case years from now. Also on this first day of spring, mourning doves were “cooing”, turkey vultures were flying overhead, and crows, tufted titmouse, black-capped chickadees, white-breasted nuthatches, hairy woodpeckers and cardinals were all flying about.

The lower Giorgetti trails were mostly bare ground with icy and snowy patches in protected spots, while the upper trails had much more snow covering the ground.

Both Rocky and Muddy ponds were mostly still frozen over, with a few small perimeter areas starting to show open water. The haunting sound of under ice rumblings could be heard at both ponds, as the ice was beginning to break up.

Gray squirrels and Eastern chipmunks were scurrying around, looking for acorns left over from the previous fall. Wintergreen was covering bare ground areas.

The next day(March 21st) I went back to the park and saw a few Canada geese at Muddy Pond in a small area of open water, along with northern juncos, and a pileated woodpecker. The first butterfly of the season, a Compton tortoiseshell, was also seen.

On March 27th, both ponds were now almost completely open, with only a few small areas on the west sides of both ponds showing the presence of ice. Wood frogs could be heard calling for the first time in areas where they’ve always been heard at the beginning of the season, and that is the Rocky Pond outlet area, and a wetland area in the woods at the south side of Rocky Pond. Also, a mourning cloak butterfly was seen on Trail 16A, near one of the American Chestnut planting plots, just where I see them at this same time every year.

On April 5th, the first wildflower, Coltsfoot, made its appearance. It’s always the first plant to flower. This was also the day I saw my first yellow-bellied sapsucker and Eastern Newt at Rocky Pond.

A few days later, trout lily leaves were starting to emerge from the forest floor, and oak trees were beginning to flower. One osprey was seen sitting on last years’ nest. Spring peepers were also heard for the first time. And I noticed many small insects flying about. Painted turtles were sunning themselves at Muddy Pond. For the most part, the forest was still very quiet.

During the middle of April, temperatures were cold on a very quiet evening walk through the forest. Wild lily-of-the-Valley leaves were emerging from the forest floor and a hermit thrush was singing its beautiful evening flute-like song. Beavers were active on the west side of Muddy Pond, and a single osprey was on its nest.

On May 1st, I went for a quiet evening walk and saw black-capped chickadees, tufted titmouse, hairy and pileated woodpeckers, robins, hermit thrush, yellow-throated vireo, and belted kingfishers and 3 osprey at Muddy Pond. In the pond were seen a large snapping turtle, painted turtles, and a river otter. Trout lily and wood anemone were in flower.

On May 9th while on an early morning bird walk, not only did I see the usual contingent of early spring birds, but also saw the relatively uncommon red-breasted nuthatch, the first time I had ever seen that bird at Pine Hill Park. A house wren could be heard singing near the trailhead.

On May 22nd, I saw my first firefly of the season, MUCH earlier than usual. A large black northern water snake was seen at Rocky Pond, and Moccasin flower, Jack-in-the-pulpit, and foam flower were all flowering. Many birds were seen, including South American migrants.

Birds seen included Hairy woodpecker, yellow-bellied sapsucker, Eastern pewee, least flycatcher, tufted titmouse, black-capped chickadee, white-breasted nuthatch, hermit thrush, veery, ovenbird, red-eyed vireo, yellow-throated vireo, black and white warbler, chestnut-sided warbler, American redstart, indigo bunting, and rufous-sided towhee.

On May 31st, the Wild American Chestnut tree was finally located on Svelte Tiger trail. Tree leaves had finally emerged, and the specific tree was easily identified.

During a walk the first week of June, I noticed large numbers of partially eaten tree leaves covering just about every trail in the park, and soon realized that the park is undergoing an infestation of gypsy moth caterpillars. By June 10th, the infestation was so bad that if you stood quietly on a secluded trail, you could hear the droppings of the caterpillars falling on the ground and upon other leaves. It sounded like a gentle rain. I’ve been hiking Pine Hill Park since 2013, and never saw as bad an infestation as this year.

I measured the height of the Wild American Chestnut tree on June 10th, and found the tree to be 66’ tall. Unfortunately, though healthy looking, it did show signs of the blight infection. On my hike back to the trailhead, I came across a recently born fawn. It calmly walked right in front of me and off into the forest.

On a walk in mid-June, I was surprised to see a Cedar Waxwing in the forest. I usually don’t see them until the end of summer, and always up around Rocky Pond. An Eastern tiger swallowtail butterfly was seen feeding on red clover, bullfrogs were croaking at Rocky Pond, and American redstart warblers and tufted titmouse birds were seen feeding on gypsy moth caterpillars. Hopefully, these, and other, predatory birds will keep the gypsy moth caterpillar numbers in check.

That’s it for this issue. Please stay on the trails, and enjoy the Wild Times of Pine Hill Park.
