Owls in the Hand: A Night at a Saw-whet Owl Banding Station

11/10/2019

RESULTS from Princeton banding station
late October-November 10, 2019

Total owls: 41 (40 not previously banded and
one foreign recovery from an unknown location)
Hatch-year: 6
Second-year: 26
After-second-year: 9

Our smallest owl, the Northern Saw-whet Owl, is a striking bird with its brown and white plumage and yellow irises. This species nests in low densities in western Massachusetts but migrate through Massachusetts in relatively high numbers during late fall. Despite being one of the most common species of owls in our northern forests, they are seldom seen.
Federally -licensed bird bander and state ornithologist Andrew Vitz (MassWildlife) hosted Club members at a banding station in Princeton on November 2nd, and he managed to capture and band several owls that were passing through the area. Once captured, the birds were banded, and data was collected on their age, sex, and condition before they were released. The data gathered will be submitted to the U.S. geological Survey Bird Banding Laboratory, an integrated scientific program supporting research and conservation of North American birds. Information gathered during banding helps researchers to learn about the owls’ movements and survival rates.
Drew writes: "Although it was the best year that I have had [banding owls in central MA], it was a poor year for most owl banders in the northeast. I am not really sure why we had such good luck, but, similar to other stations, we had very few hatch year (HY) owls [young of this year]. This pattern is indicative of poor nesting success for the owls this year. I expect with a good acorn crop this year that the small mammals will be abundant in 2020, and the owls will respond accordingly. "

Drew Vitz and friend.

THANK YOU to Ted Purcell and Drew Vitz for the photographs.

A Medley of Late Season Insects

11/1/2019

0 Comments

An Oil Beetle (Meloe impressus) in the blister beetle family. Lacking wings, these beetles are flightless. Their name derives from the phenomenon wherein they emit an oily substance, cantharidin, from their leg joints when disturbed. Petersham, 8 September 2019 by Alan Rawle.

A nice find was this Milbert's Tortoiseshell (Aglais milberti) on 19 October in New Braintree. According to butterfliesofmassachusetts.net, although this species has been seen at many locations over the years, there is a lack of known colonies which persist from year to year. This suggests that most Massachusetts sightings are the result of periodic dispersions from further north, which establish temporary breeding populations but probably do not persist for very many years. Photo by Alan Rawle.

Male Northern Walkingstick ( Diapheromera femorata) found in Rutland 24 August by Doug Wipf. Adults are present in August and September in the northern part of the range, but because of their tendency to feed high in the canopy, the insects are seldom seen.

Female Fork-tailed Bush Katydid (Scudderia furcata) 23 September 2019 Princeton, by Doug Wipf

Common Looper (Autographa precationis) observed on 29 September. Larvae feed on a variety of forbs (non-grass herbs) such as aster, cabbage, plantain, and clover.

Usually heard singing from the underside of branches or broad leaves, Snowy Tree Crickets (Oecanthus fultoni) can be found close to the ground--a warmer microenvironment--during cold spells. That was the likely scenario on 30 October in Rutland. Photo by Ted Purcell.

This male Autumn or Yellow-legged Meadowhawk (Sympetrum vicinum) was in Paxton on 26 October and could well have lingered through November. Distinguished from other late-flying small, red dragonflies by leg color and red face. Photo by Bill Platenik.

A caterpillar that will metamorphose into a moth that resembles a dry, curled leaf--Angus' Datana (Datana angusii). Found feeding on oak, 14 September, Hardwick, by Alan Rawle.

A female Differential Grasshopper (Melanoplus differentialis). Females are identified by their larger size--this one was almost 3" long-- and ovipositor extending beyond wings and showing two triangle-shaped cerci. Photographed in Rutland 4 October by Ted Purcell.

A late Pecks' Skipper (Polites peckius) on 18 October in Hardwick.

Photographed by Pam Banach on 2 October 2017 in Worcester, this Greater Angle-wing (Microcentrum rhombifolium) Katydid is an excellent example of a leaf mimic. This appearance serves as a better protective strategy when the katydid is amongst greenery as opposed to being exposed on pavement, but it's still a good disguise.

Autumn or Yellow-legged Meadowhawk (Sympetrum vicinum) is the last odonate of the season to be seen on the wing. They're often found far from water, foraging over fields, even into November. This female was in Hardwick 22 September. Photo by Alan Rawle.

On 26 October this Green Stick Bug (Chinavia hilaris) was probably looking for something green to eat. The species feeds on many plants, including native and ornamental trees, shrubs, vines, weeds, and some crops. The preferred hosts are generally wild plants, but as these plants mature the bugs may make pests of themselves by switching to cultivated crops. Photo taken in Paxton by Bill Platenik,

Another Northern Walkingstick, this time found 28 September, also in Rutland, by Ted Purcell. The growing insects prefer the leaves of American hazelnut (Corylus americana) and black cherry (Prunus serotina), but where these are scarce, they are likely to be on white oak (Quercus alba).

Two-spotted Tree Cricket (Neoxabea bipunctata) is one of the common late-season songsters in our region. They're seen more than they're heard! Go to: http://songsofinsects.com/crickets/two-spotted-tree-cricket to listen. Rutland, 24 September by Doug Wipf.

Male Differential Grasshopper (Melanoplus differentialis). The abdomen of the male is rounded and dips into a subtle curve before tapering at a slightly raised angle. 22 September 2019, Hardwick, by Alan Rawle.

This female Giant Ichneumon (Megarhyssa atrata) was found ovipositing on 14 September in Hardwick. She detected a type of horntail larvae, probably Pigeon Horntail (Tremex columba), deep inside a dying maple tree with her antennae, sensing a fungus associated with the larvae. The eggs were deposited on the larvae and will consume the larvae upon hatching. Insertion of her 5.5 inch ovipositor was accomplished with the help of a chemical that breaks down wood fibers.

The more familiar form of the Isabella Tiger Moth (Pyrrharctia isabella) is the larval stage, the Woolly Bear caterpillar. This one was photographed on 21 September in Hardwick by Wendy Howes. Do they really predict winter weather? For a discussion of this notion, go to: https://www.almanac.com/content/woolly-bear-caterpillars-and-weather-prediction

Eastern Comma (Polygonia comma) on 29 September 2019. This butterfly has two broods, and the ‘winter form’ flies from early September to mid-November, then hibernates over the winter as an adult, sometimes emerging during warm spells. It then flies again early March through May.

Pine-tree Spur Throat Grasshopper (Melanoplus punctulatus) is not commonly seen, partly due to its cryptic coloration and pattern. Photo by Doug Wipf, 23 September in Rutland.

The Not-So-Lazy Days of Summer

8/30/2019

0 Comments

Central Massachusetts naturalists are far from lazy when summer arrives! Club members have been busy monitoring grassland birds, tracking down Lepidoptera species, watching and counting birds, setting up backyard wildlife cameras, hiking in our wonderful protected open spaces, photographing flora and fauna. . . in general, putting a lot of time and effort into enjoying and appreciating our local natural history.

On 19 July, Anne Greene captured this Bobolink in full song at Rutland's Glenwood School fields.

Two hikers shared the Quabbin Gate 45 trail with this black bear for a minute on 22 June before it looked around and saw them. Within seconds the bear vanished into the woods. Photo by Alan Rawle.

Canada Lily (Lilium canadense) was one of many species of wildflowers that were abundant as a result of the wet spring. New Braintree, 6 July. Photo by Alan Rawle.

A Great Egret at Eagle Lake in Holden posed for Ted Purcell on 26 July.

The spider species Argiope aurantia is commonly known as the yellow garden spider, black and yellow garden spider, golden garden spider, writing spider, zigzag spider, corn spider, or McKinley spider. This attractive, well-fed female was at Moore State Park in Paxton on 27 August and photographed by Bill Platenik.

A Wild Turkey ( Meleagris gallopavo) made its way to a favorite roost 40 feet up in a white pine in Hardwick in July. Photo by Alan Rawle.

A bright Cottonwood Dagger Moth (Acronicta lepusculina) caterpillar was hard to miss on 21 July in Hubbardston.

Identifying a Large Maple Spanworm moth (Prochoerodes lineola) photographed by Doug Wipf in Rutland was tricky because the colors and markings of the species can be quite variable.

The underwing view of the Eastern Comma butterfly (Polygonia comma) explains its common name. Photographed on 10 August by Alan Rawle.

The distinctive leaves of Large Whorled Pogonia (Isotria verticillata) peek out from other shaded woodland plants on protected land in Hardwick. This member of the orchid family occurs on the Massachusetts NHESP "watch" list as it is uncommon in many locations. Its status in other New England states ranges from rare to uncommon to potentially extirpated.

After the Glenwood School fields in Rutland were mowed, these two immature or female Bobolinks were taking shelter in a sumac stand at the field's edge. Photo taken on 26 July by Ted Purcell.

Both Yellow-billed (Coccyzus americanus)--above by Alan Rawle--and Black-billed (Coccyzus erythropthalmus) Cuckoos--on left by Anne Greene--were seen on most birding trips around the region for the third year in a row, a result of the gypsy moth infestation.

A bull moose on 27 August on a trail out of Quabbin Gate 45 has already grown an impressive set of antlers as autumn approaches.

Anne Greene spotted this immature male Rose-breasted Grosbeak (Pheucticus ludovicianus) in August. Over the winter in Central or South America, he'll molt his juvenile feathers and take on the striking black, white, and red plumage we see in the spring.

Bill Platenik of Brimfield sent us the two images below that were captured by the wildlife camera in his yard on 29 August at 4:42 p.m.
The fate of the gray squirrel is unknown.

More typical of the kind of wildlife photographs taken by trail cameras is this Eastern Coyote marking his territory in Doug Wipf's Rutland yard on 30 August. The coyote was likely inspired by the scent of the dog that lives there.

A Long-tailed Weasel (Mustela frenata) that was tending a nest of mewing young in Deerfield on 4 July has "weaseled" its way into the wildlife sightings of central Massachusetts.

A mosaic of bladderwort (Utricularia sp) and reflected pond water communicates serenity in this photograph by Anne Greene.

MORE WINGS!

Celebrating the 4th of July holiday were these Red-eyed Vireos (Vireo olivaceus) caught in mid-flight by Alan Rawle.

Snowberry Clearwing moth (Hemaris diffinis) on Verbena bonariensis, a non-native tropical plant of South America which is annual in our region. The flower is a strong butterfly attractant and wonderful to have in the home garden, but it may re-seed vigorously, so try to keep this non-native under control if you decide to grow it. This was a "good" year for our hummingbird moth species. Photo by Anne Greene in Rutland.

A fresh American Lady (Vanessa virginiensis) was found by Bill Platenik at Moore State Park in Paxton on 27 August.

Brilliant red Royal Catchfly (Silene regia), a rare and declining midwestern wildflower grown here in cultivation, attracts an immature Ruby-throated Hummingbird. Photographed in Hardwick on 30 August by Alan Rawle.

The striking pattern on this Clymene Moth (Clymene haploa) caught the attention of Doug Wipf in Rutland on 28 July.

Cedar Waxwing (Bombycilla cedrorum) on 27 August in Paxton. Photo by Bill Platenik.

Take a second look! This is a Viceroy (Limenitis archippus) observed at Moore State Park by Bill Platenik on 25 July. Viceroys sometimes get overlooked, especially in years with numerous Monarchs about, such as summer 2019.

Northern Pearly-Eye (Enodia anthedon) found on a partly-shaded woodland path in Hardwick on 4 August. Photo by Alan Rawle.

Rather disconcerting is this excellent photograph by Anne Greene portraying the result of brood parasitism by a Brown-headed Cowbird ( Molothrus ater). As Cornell's allaboutbirds,org website explains, "Female cowbirds forgo building nests and instead put all their energy into producing eggs, sometimes more than three dozen a summer. These they lay in the nests of other birds, abandoning their young to foster parents, usually at the expense of at least some of the host’s own chicks." Despite our distaste for this survival strategy, we have noticed that, in our region, cowbirds select the nests of some of our most abundant species in which to lay their eggs. The population of American Redstart (Setophaga ruticilla)--the adult male is seen here--is fairly stable world-wide, so this incident of parasitism can be put in perspective. Warbler losses due to man-made hazards and causes are much more of threat.

Ephemeral spring wildflowers and wildlife sightings

5/12/2019

0 Comments

In the world of natural history, the term "ephemeral" is generally used in reference to spring wildflowers that bloom briefly. Although wild birds and animals have longer lifespans than the short-lived blossoms on many of our early-season plants, actual sightings of wildlife are often equally fleeting and transitory. The critters shown here appeared for an ephemeral moment to some quick and alert photographers.

One of our favorite early spring ephemerals: Bloodroot (Sanguinaria canadensis) in New Braintree 8 May 2019. Wesuspect it's a favorite because it blooms around the time we start to wonder if spring will ever come.

Yellow-throated Vireos (Vireo flavifrons) started arriving from their wintering grounds in Central & South America and some Caribbean Islands the second week in May. Vireos are not as ephemeral as some of the fast-moving warblers. Photo by Alan Rawle, Hardwick, 11 May 2019.

On 5 April, Doug Wipf had to get his camera focused quickly in order to capture a picture of this American Mink (Neovison vison). This semiaquatic mustelid is described as restless, curious, and bold.

This Eastern Bluebird (Sialia sialis) pair, oblivious to the Red-bellied Woodpecker lurking in the background, engaged in courtship feeding of dried mealworms in Rutland on 3 May 2019. Photo by Ted Purcell.

The Eastern Pine Elfin (Callophrys niphon) will lay its eggs on buds of White Pine and other species of pine, one of the few butterflies to use conifers as host plants. Not a particularly rapid flier, this butterfly was less ephemeral than some. New Braintree 8 May 2019

Ted Purcell found this Broad-winged Hawk (Buteo platypterus) perching longer than expected in Rutland on 12 May 2019.

The colorful Jack-in-the Pulpit (Arisaema triphyllum) is pollinated by flies. Watch for the bright red berries later in the fall. But for now enjoy the spring appearance! Photo by Joanie Gentian 8 May 2109.

A Spring Peeper (Pseudacris crucifer) spent a short time on a glassdoor pane in Hardwick on the night of 7 May. This was an ephemeral sighting, but the evening chorus of peepers will continue for many more weeks.

Even if you just catch a flash of orange and black out of the corner of your eye, you'll know that Baltimore Orioles( Icterus galbula) are back in central Massachusetts. Photo by Alan Rawle, 15 May, Hardwick.

Trout Lily (Erythronium americanum) was just beginning to bloom on south-facing slopes alongside wooded wet areas in New Braintree 8 May 2019.

Sporting bright breeding plumage as he heads into the nesting season, this White-throated Sparrow in Rutland on 3 May was on the verge of departure for more optimal territory. Photo by Ted Purcell.

Despite weighing from five to twelve pounds on average, with some large individuals getting up to as much as fifteen pounds, the Groundhog (Marmota monax) can disappear from view at astonishing speed when it senses danger. This one made an ephemeral appearance lasting only a handful of seconds. Inspired by the photographer's presence, it retreated to the safety of its burrow. Photo 20 May 2019 by Alan Rawle, Hardwick.

A Closer Look at Those Dead Trees. . .

3/27/2019

0 Comments

From Atlas of Polish Mushrooms https://www.grzyby.pl.pl/gatunki

. . .that from afar look like they've had their bark pecked away so that the pale cambium layer is exposed. While walking in the woods this winter, we occasionally observed, from a distance, trees that appeared to have been severely ravaged by Pileated Woodpeckers. Usually these were small (<12 inches in diameter) and clearly dead trees, and our recollection is that they were pines. The bark removal, which is what it looked like to us, extended up and down almost the entire length of the trunk. Having rarely come upon trees with such extensive excavation, we walked over to see more clearly. What we saw--and it's embarrassing to admit how many times in subsequent hikes we continued to be lured by the illusion--was a massive fungal layer, pale in color, engulfing the tree. "What IS this stuff?!?" a few of us wondered.
Finally samples were obtained and sent off to two fungi enthusiasts who have provided mushroom/fungi education at Club functions, Joe at Mass Audubon, and David Hibbett at Clark University. Fungi expert Larry Millman also weighed in after he examined a specimen we sent. Larry wrote: "Its hyphal system, basidia, spores, and substrate indicates that it’s Perenniporia subacida." The color is somewhat darker than most specimens I’ve seen of this species, but age can change colors. . . and, as Leif Ryvarden says of P. subacida, “A very variable species.”
We seem to have had a bumper crop of Perreniporia subacida this winter, likely due to the extreme humidity and high rainfall of summer/fall 2018.
Perenniporia is a genus that includes bracket-forming or crust-like polypores. Polypores are a group of fungi that form fruiting bodies with pores or tubes on the underside; most inhabit tree trunks or branches, consuming the wood. We're more accustomed to seeing polypores in the form of "shelf mushrooms" or brackets growing perpendicular to the trunk. The crust formations sure had us fooled until we took a closer look. Glad we did!

Winter 2018-2019: Keeping Us On Our Toes

3/2/2019

0 Comments

One thing we can say about winter in central Massachusetts is that there are always surprises--amount of snowfall; freeze-and-thaw cycles; bird visitors from the north; breeding birds that didn't migrate south; resident bird populations seeming to be "up" or "down"; mammal movements. Temperature-wise it was a real roller-coaster ride affecting semi-hibernation patterns of raccoons, opossums, and other animals. Snow fleas, or springtails, (Hypogastrura nivicola) put in an appearance in Petersham on 3 February, between bouts of single-digit night-time temperatures.
There was constant refrain of "No birds are coming to my feeders!" especially during the first half of the season. Was this due to the lack of snow cover and the dispersal of our usual feeder visitors? On the other hand, some uncommon species were noted, and high numbers of Cooper's and Sharp-shinned hawks and Barred Owls seemed to be popping up everywhere. This was probably partially linked to the heavy mast year (acorns and other seeds) that provided so much food for rodents in fall 2017. Raptors and owls raising young in 2018 should have had abundant food and thus more successful broods. Voila! More owls and hawks in the landscape. According to some biologists, some of these hawks and owls likely were from regions north of Massachusetts.
Small local irruptions of a few other northern breeding birds, including Evening Grosbeaks and Pine Grosbeaks, occurred throughout the area. And, although feeder activity was low in some places, feeder-watchers who persisted and occasionally fed high-quality items such as mealworms eventually attracted a variety of visitors.

When it comes to preference by birds, not all crabapple trees are created equal. The fruit of some cultivars remain untouched in even the coldest weather. Obviously the trees at MWCC are the "right" species of crabapple. We would welcome information from botanist(s) about which crabapple species to plant if we want to attract fruit-eating birds to our properties. Photo 26 January 2019 by Doug Wipf.

The Open Half of Winter 2018-2019

1/23/2019

0 Comments

Winter remained open throughout December and into January, so we scheduled an exploratory hike on January 19th to Rum Rock and Osgood Swamp, a section of Mass Audubon's Rutland Brook Sanctuary near the Barre/Petersham town line. Temperatures were in the brisk 20s F, and the woods were still and quiet. Nevertheless, signs of ongoing animal and bird activity were everywhere--fresh woodchips and exposed rotted tree cavities produced by woodpeckers, the pungent odor of a porcupine shelter in a small den under a rocky outcropping, coyote and deer scat, and--most dramatic--extensive evidence of high beaver activity. Beavers continued to practice their superior engineering skills as long as they could still move through the water. Remember that very wet fall? Plenty of pretty high water--becoming ice-- everywhere!
Besides the truly impressive glacial erratic known as Rum Rock, scenic interest was provided by granite ledges, caves, ice formations, lichens, and ferns, as well as views of the expansive wetland.
Many thanks to tracker-naturalist Nate Rosebrook for the photos.

Bobolink Summer

9/15/2018

0 Comments

Courtship display by male Bobolink at Moore State Park, Paxton, June 2018 by Bill Platenik.

Our Grassland Bird Initiative volunteer teams monitored several central MA locations this summer. Bill & Carol Platenik made dedicated weekly visits to Moore State Park in Paxton, where a bird-friendly mowing regime has been established. Todd& Alice Livdahl and Wendy Howes observed at Mt. Jefferson Conservation Area in Hubbardston which used to (and may still) designate one field for mowing after July 4th. At DCR Ware River Watershed Prison Camp fields in Rutland, with a current mowing contract stipulating mowing after August 1st, Doug Wipf and Linda Mueller made regular visits throughout the nesting season. We are still looking for volunteers to monitor High Ridge WMA in Gardner/Westminster. Bobolinks nested there successfully this year, but no one was able to formally monitor. The WMA has established late mowing--after August 1st--regimes for all the fields, so prospects for grassland bird species are very good there.
Volunteer Ted Purcell observed a town-owned field at Glenwood School in Rutland and found many Bobolinks early in the season, but the fields are part of the Town's mowing contract and are not currently being managed for wildlife and grassland birds.
Photographer Anne Greene of Rutland found Bobolinks at fields owned by Alta Vista Farm in Rutland and gave the owners information about grassland birds available through Mass Audubon: https://www.massaudubon.org/our-conservation-work/wildlife-research-conservation/grassland-bird-program
Overall it was a good year for Bobolinks in both protected and non-protected areas. High amount of rainfall caused some haying delays which benefited birds. Heat and humidity helped insect populations and therefore boosted Bobolinks' food supply. The highest number of Bobolinks were encountered at Moore State Park, where a huge flock of over 130 birds--including adults and this season's fledglings--was seen in mid-August.
Thanks to all who pitched in on behalf of grassland birds!

DCR's Moore State Park in Paxton has adopted field management guidelines that allow mowing of pathways of the perimeters of all fields along the walls and a single mower width path through the center of the largest fields. Agricultural mowing of the hay/tall grass will take place after the nesting season, in August or September.
One of the center paths, which is maintained starting in April and therefore not attractive to Bobolinks, is shown here. It also provides good access for bird monitoring.
