Please respect the privacy of the bears and the landowners, to whom we are extremely grateful for their enthusiastic cooperation in allowing us to share this peek into the lives of black bears. This is a top-notch camera with audio and infrared illumination night vision provided and powered by HDOnTap. It can be controlled remotely and has the ability to pan, tilt and, zoom.
Being under a residential deck is not an unusual denning situation for this region of the state. The sow and cubs are generally not a threat to the residents, nor are the bears affected by the normal human activity around this home.
When she leaves with the cubs, she will most likely head out to the large wooded area behind the home where she'll find a place to teach the cubs to climb and search for food.
The sound of a nursing cub sounds like a purring car that just won't turn over. You might hear a cub bawling. Sows communicate to their cubs with low grunts, huffs and mumbles. You may hear water dripping from snow melt, birds chirping, and the occasional passing of the human residents. Litter sizes range from one to five, with three most frequent in Pennsylvania. Females give birth in the January while in the winter den. Newborns are covered with fine dark hair, through which their pink skin shows.
At birth, they are about nine inches long and weigh 10 to 16 ounces. Their eyes open after about six weeks. A female black bear generally raises one litter every two years. In most cases cubs den with their mothers for their first winter.
This adult female has ear tags, which indicates she previously was handled by Game Commission staff. We believe this is not the same sow that denned here in Viewers have captured some nice images of the numbers on the right ear tag. Our best analysis leads us to believe this sow is now 7 years old.
She is estimated to weigh about pounds. She had three cubs with her when she was captured in Sows typically have cubs every other year, which puts her on the right cycle for cubs this year. If you get a clear shot of one of the ear tags, continue to let us know.
While this female black bear found this space under the deck of a residential home a suitable den, winter dens could also be a hollow tree, an excavation resembling a bear-sized groundhog hole, a rock crevice, cavity under large rocks, or in a nest beneath the roots of fallen trees.
Bears line their dens with bark, grasses and leaves. Females tend to select more sheltered sites than males. Males den alone, as do pregnant females they give birth in the den. Females with first-year cubs den with their young. Adult females will, on rare occasion, reunite with their 2-year-old offspring and have cubs at the same time in the den, but never an adult male. There is limited room under the deck and the sow must lay on her side to nurse. In winter, bears den up and become dormant.
They lapse into and out of a deep sleep, from which they may be roused. Body temperature decreases by 10 to 12 degrees Fahrenheit from a normal degrees to about 88 degrees , and metabolism slows significantly. Heart rate and respiration slow down. This helps the bear keep its fat reserves as long as possible. Movement is limited, so as not to expend much energy while in the den.
Sows will move and adjust with the cubs now and then. Males and lone young adults will occasionally rouse from sleeping and wander on the landscape. Bears are alert and active during hibernation; but don't leave the den or take in any food or water. They do not urinate or defecate while dormant. It is not uncommon for female bears to use dens with less overheard shelter than they have under this deck.
Although females with cubs tend to use more sheltered dens, many frequently den in the open with only a few twigs overheard. Cub survival is high in both situations. If a den gets too wet during the spring thaw, the sow may move the cubs to a dryer location nearby. The Game Commission monitors bear populations statewide by tagging approximately bears each summer, and then watching for the recovery of those tags in the fall harvest.
Each county in the primary bear range is assigned a tagging quota so that tags are well-distributed across the state, and Game Commission staff in those counties work toward that quota each summer.
Some bears are captured in nuisance situations. Some bears are captured for research purposes and to meet the tagging quota, without any history of being a nuisance. It is impossible to tell the reason for capture without looking up the tag number. Tags are made of stainless steel and look silver when first put on a bear, but dull to a brownish tin color as they weather.
The tags crimp over the top leading edge of the ear, close to where the ear attaches to the head. Powered by Tyler Technology's OneOutdoor.
