Wildlife and Nature Photos from Delaney WMA

This blog showcases the wildlife and natural beauty of the Delaney WMA. Many of the photos were taken at night, using a motion-sensing camera.


Beaver cutting a tree at Delaney

For the past few weeks, a beaver has been diligently gnawing away at the base of this tree. A raccoon and a fisher stop by occasionally to check on the progress.


Buck marking his territory at Delaney WMA

This monster buck recently-scent marked a pine and scraped the ground, leaving his scent to mark his territory.

Delaney Beaver at Work

As winter approaches, Delaney’s beaver population is busy at work, adding mud to insulate their lodges against the cold. Active lodges will have a muddy path leading up one side, and if you’re lucky, you might see the beaver’s webbed footprint in the muck.

Active lodges will also have a food cache nearby – a half-submerged pile of recently cut saplings and branches. Once Delaney freezes over, the beavers will feed upon the underwater cache throughout the winter.

In contrast, an abandoned or inactive beaver lodge will have lost most of its mud, and will be topped with whitened logs that have weathered in the sun over the years. Purple loosestrife and other vegetation may have sprouted and grown up from the lodge. There won’t be a cache of food adjacent to the lodge.

The beaver captured in these photos was out working on his lodge every night. He’d make his first appearance an hour or so after sunset, and then make repeated trips up and down the side of the lodge, hauling mud, muck, and sticks. Notice how he walks on his two hind feet, pressing back on his flat tail for balance.

Surprisingly, this lodge doesn’t have a food cache yet. Unless this beaver gets busy, he may not make it through the winter.

Old North Bridge Hounds

On Tuesday, Nov 16, 2010, the Old North Bridge Hounds hunting club will have their final hunt of the year at the Delaney Complex. They’ll be starting out at 10AM from the dam at the south entrance off Harvard Rd. If you haven’t seen them in their fall finery, it’s quite a sight!

I came across the riders and hounds one day back in 2009, and they were more than happy to have me ride along in one of the support cars, asking questions and taking photos. My first question, and the question that gets asked most often, was “are you really hunting for foxes?” No, the “fox” in this case is a scent bag full of anise, which a volunteer drags along the course earlier in the morning. The hounds (don’t call them dogs!) follow the scent trail, and the riders follow the hounds.

The hounds wear radio collars so they can be tracked down if one runs astray, and there are checkpoints, head-counts, and water breaks for the animals (and riders) when they cross Finn Rd.

Come out and watch the hounds as they hunt on Tuesday, 10-12. Leave your dogs at home, or keep them on a short leash. For more information about the hunt club and their schedule of fixtures, visit http://oldnorthbridgehounds.org/


Treetops Ablaze! Another Spectacular Delaney Sunset

As I raced down to the boat launch at the Delaney Project to photograph last night’s amazing sunset, I was bowled over by this view. It looked like the woods had erupted in flame. These white pines along Harvard Road seemed ready to ignite at any minute.

Fiery Sunset at Delaney WMA


You may not ever see a beaver out and about at the Delaney Wildlife Management Area, but you can’t walk or paddle very far without seeing signs of their presence. Freshly-chewed poplar and alder branches wash up on the beach and the boat launch. Scent mounds serve as territorial boundary markers along the shore. Stick dams impound the waters in the wetlands above the Future Electronics spillway and clog the drainage culvert underneath Finn Road.

And of course there are the beaver lodges out in the ponds. How many lodges are there at Delaney? I know of seven, in various conditions, scattered throughout the property. Some are active lodges, with fresh mud and a submerged cache of recently-cut branches which will sustain the beavers under the ice until spring. Others have been abandoned for years, bleached white in the sun and sprouting purple loosestrife and other vegetation. How many have you seen?

Life and Death at Delaney

I spent much of Saturday exploring the Delaney Project, and came across two reminders of the cycle of life and death that plays out in the natural world.

As I walked through a stand of white pine along the edge of the wetlands, I glimpsed a red-tailed hawk being pursued through the trees by a single, angry crow. The hawk seemed reluctant to leave the area, flying to the next tall pine, only to be set off again by his attacker. Both finally flew off, and the forest returned to silence.

A minute later, I came across the still-warm body of a gray squirrel lying dead at the base of a pine. No doubt the hawk had caught the squirrel only moments before, but had been forced to abandon his meal when set upon by the crow.

Curious to see what would happen next, I took a two-hour detour to pick up a camera and left it monitoring the site. I half-expected the hawk to have returned for his dinner, but he had moved on.

Later that day I came across another kill site closer to the wetland edge. Here the weathered rib cage and vertebrae of a white-tailed deer lay half-buried in the oak leaves. Had this deer been killed by coyotes? Broken a leg crossing the ice? Or had it simply run out of food at the end of winter and collapsed in starvation?

I returned from my walk grateful for having witnessed these events of life and death unfold in the woods of Delaney.

Hard Frost

After all the pleasant, sunny autumn days of October, November has started off with an icy chill. A hard frost coated every surface this morning, transforming the meadow at Delaney into a field of white and gray.

Oak leaves wafted down from the treetops, not even needing a puff of wind to detach them after the cold night.

Rutting Deer Running Rampant!

This is the time of year when deer are on the move at Delaney. You may see them running through fields, crossing trails, or darting out into the road at this time of year, even in broad daylight. A doe bounded out of the woods in front of me on a recent walk at Delaney, and seemingly everywhere I look in the woods now, I see fresh signs of deer.

It’s deer mating season, and during the rut, the male bucks are spending all of their energy looking for females in estrus. They leave behind two easily-identifiable signs which you can look for when walking the trails at Delaney in the fall: rubs and scrapes.

Male deer rub their antlers on saplings, and the torn bark and shiny wood underneath is visible to does (and hikers) from a long distance off. If you can find one rub, turn around 360 degrees and try to locate another. A buck will often rub trees along his favorite deer trail, and you can follow his progress through the woods.

Scrapes are another sign that there’s a buck in the area. Look for a V-shaped scratch in the dirt, often underneath an overhanging branch that may have the tip broken off or hanging down. The male will scrape back with his front hoof, urinate into the scrape to leave his scent, and also rub the branch with glands on his head to deposit scent. Does will be attracted to the disturbed patch of earth and leave their scent as well.

I’ve been monitoring this buck scrape at Delaney for the past week, and each morning there are fresh tracks around it. In the video below, you can see the buck that made the scrape returning to freshen it up (at 7PM and midnight) and to check whether any receptive females have been in the area. Halfway through the video, the buck notices the red glow from the camera’s infra-red lighting, and stomps on the ground. Later, when the buck returns to the scrape, a second deer (a doe?) emerges from the woods, and the buck rushes off to investigate.

Delaney Sunset

I looked out the window at 6PM this evening and saw a pink wisp of clouds to the north, catching the light of the setting sun. I grabbed my camera and ran to Delaney, where a spectacular sunset display of reds and yellows was reflected in the water. A motorcyclist had his camera phone out, and as I took photos another neighbor drove up and jumped out with his camera.

We watched in awe for about 5 minutes, and then it was gone.
