Bull Moose Starts Courting a Cow as the Moose Rut Begins
The moose rut, also known as the mating season or mating period, is a critical and fascinating time in the life cycle of moose (Alces alces), particularly in North America where moose are prevalent. The rut typically occurs in the fall, from late September to early October, varying slightly depending on the region and the specific population of moose. During the rut, male moose, known as bulls, become highly active and aggressive as they compete for the attention of female moose, or cows, for mating opportunities. The primary purpose is to reproduce and ensure the survival of their species.
Bulls become more territorial and establish dominance hierarchies among themselves. They use vocalizations, displays of aggression, and physical combat to establish their rank and gain access to receptive females. Bulls use various vocalizations during the rut to communicate and establish their dominance. These include grunts, bellows, and roars, which can carry over long distances and help in attracting females and deterring rival males.
Bulls exhibit physical displays of dominance to assert their position. This can involve posturing, such as standing tall and erect, as well as charging and clashing antlers with other males. The large and impressive antlers of the male moose play a vital role in their competition for mates. Bulls use their antlers for both display and actual combat, engaging in shoving matches to determine dominance and mating rights.
Moose Rut Courtship - Once a dominant bull establishes itself, it will attract and mate with receptive cows. The courtship and mating process typically involves pursuing and herding a cow or groups of cows.
Mating during the rut ensures that calves are born in the spring, providing them with the best chance for survival and growth due to the abundance of food during that time.
The rut can last several weeks, with peaks of activity occurring when females are in estrus and most receptive to mating. The exact timing of these peaks can vary based on geographic location and local environmental factors. Female moose play a crucial role during the rut by selecting mates based on the displays of dominance, antler size, and overall health demonstrated by the competing bulls. Their choices help ensure the passing on of strong genetic traits to their offspring.

Bull Moose Heads into the Lake for Sustenance on a Beautiful Evening
When Moose wade into lakes or other bodies of water, they primarily feed on aquatic vegetation. Moose may eat the leaves, stems, and flowers of water lilies, which are common in many freshwater lakes and ponds. Moose Bulls and Cows will eat Pondweeds that are submerged aquatic plants of which are partially submerged in lakes. Water Horsetail, also known as scouring rush plant grows in shallow water and is a part of a moose's diet. Various submerged grasses that grow in lakes can be consumed by moose when they forage in the water and other aquatic vegetation depends on the specific location and ecosystem. While Moose are not underwater grazers like some marine animals, they do often venture into the water to access the plants growing near the shore or partially submerge themselves to reach submerged vegetation. This feeding behavior allows Moose to meet their nutritional needs and put on weight before and during the Moose Rut and then Winter.

Moose Bulls with Fibromas Tumor Growths
Being the most common tumor reported among moose, these growths are likely benign fibromas, a wart like growth protruding from the skin. The fibromas can be smooth or appear cauliflower shaped, ranging in size from a few millimeters to over 10 centimeters in diameter. They can be hairy or bald in nature. These growths can be in multiples and can become infected with bacteria if cut and do look quite gross, but they apparently do the Moose no harm. Eventually these sores will regress and disappear. Bulls are typically fine and Moose Cows with these growths will continue to have healthy offspring.
